If unit was initially licensed in SAF factory premises, licenses can be managed using ‘License management' section in Web GUI.
We are installing a link and we are not able to achieve calculated Rx level. Our signal is for 30 dBm lower then expected. What is the procedure to solve this issue?
Checklist for solving such issue is as follows:
1) Was the link tested in lab before? It is highly recommended to verify equipment operation in lab before installation on sites.
2) Is there clear line of sight between antennas? It is not enough just to „see” the remote antenna. Fresnel zone clearance also should be considered. An obstruction within the Fresnel zone can cause signal attenuation due to diffraction.
3) Is Tx power configured on maximum allowable value? It is recommended to set maximum allowable Tx output power on both radios during link installation and antenna alignment.
4) Is polarization of antennas and radios the same on both ends of link? Be sure that both antennas and ODUs are installed in position of the same polarization on both sites.
5) Is the same frequency channel set on both ends of the link? It is mandatory that on both radios is set the same frequency channel.
6) Are ATPC and ACM features disabled? All additional features which can change parameters, such as Tx power and modulation must be disabled during link installation. Only after successful link installation those features can be enabled.
7) Do antennas support the same frequency as radios? Be sure that antennas support the same frequency range as radios.
If all mentioned points above are verified and diagnosed as correct then repeat antenna alignment procedure from the beginning.
What kind of connector do 6GHz CFIP radios have for antenna interface?
6GHz CFIP radios have N-Type female connector.
What should be considered when installing 24GHz radios?
SAF Tehnika's 24GHz radios utilize both polarizations for duplex transmission, therefore radio should be installed with 90 degrees offset regarding remote side of the link.
Is it possible to use engineering order wire using your equipment?
EOW (Engineering Order Wire) in CFIP PhoeniX, PhoeniX M and CFIP Marathon is realized using 3.5mm headset.
In case of CFIP-106/108 FODU and CFIP Lumina FODU you can use an IP phone for EOW purposes.
Is it possible to use coaxial cable other than RG213 and LMR400 to connect IDU to ODU?
It is possible to choose any other coaxial cable, but main thing is to ensure that this cable has 50 Ohm impedance and total attenuation per the necessary cable length does not exceed 20dB at 350 MHz frequency. SAF does not guarantee proper operation of the link in case cable attenuation exceeds 20 dB.
Is Ethernet in the first mile OAM (operations, administration, and maintenance) (802.2ag, 802.3ah) supported throughout SAF products.
At the moment SAF products do not support Ethernet in the first mile OAM.
What are Cisco router traffic shaper settings for Ethernet interface?
Cisco router traffic shaper settings for Ethernet interface going to microwave link shall be as follows:
traffic-shape rate bit-rate [burst-size [excess-burst-size ]]
traffic-shape group access-list bit-rate [burst-size [excess-burst-size]]
The former command traffic shapes all traffic on an interface. The latter uses an access-list to specify which traffic is to be traffic shaped.
bit-rate: Bit rate that traffic is shaped to in bits per second.
burst-size: Sustained number of bits that can be transmitted per interval. The default is the bit-rate divided by 8.
Burst size cannot exceed half of switch/bridge buffer size.
excess-burst-size: Maximum number of bits that can exceed the burst size in the first interval in a congestion event. The default is equal to the burst-size.
The measurement interval is calculated by dividing the burst-size (if non-zero) by the bit rate. If the burst-size is zero, the excess-burst-size is used (if non-zero).
Here is command example for 34 Mbit link:
-------------------
traffic-shape rate 31000000 124000 0 1000
What is the network planning tool you recommend to deploy SAF products?
Generally, you need SAF provided Path calculation tool, but in case of verifying Fresnel zone clearance, when inspecting path profile, you should use "Pathloss".
We have tested 313 Mbps link, but result is much lower than 313Mbps. What is the reason?
There could be many reasons why you do not see expected bitrate with your tools:
- Wrong tools used - dedicated hardware Ethernet tester should be used to test actual performance of test subject.
- Misunderstanding of Ethernet speed - declared speed is Ethernet Layer2 payload speed (1518byte packets).
- Measurement integration period and test traffic bursts are not taken in account - Let's think about different ways of transmitting information at 313 Mbps.
a. transmit one bit each 1/313000000 second (as radio link does)
b. transmit 39125 bytes, then pause one millisecond
c. transmit 39125000 bytes, then pause one second
So you see that option a and maybe b is more or less real, but option c is unlikely even on Gigabit Ethernet. That is - all mentioned transfer methods give the same average bitrate of 313 Mbps. Option c is impossible on SAF products because of switch buffer limitations. This is a well-known side-effect of Ethernet bottlenecks. You shall either make your traffic not so bursting or, if possible, use traffic shaping services of your Cisco Switches to limit traffic flow at exactly 313 Mbps - then it is upon your switch what to drop and how.

How is it possible to upgrade CFIP/CFQ/CFM link capacity?
Capacity of equipment operating at full capacity cannot be increased with software upgrade, though every system can have capacity initially limited by means of licensing (CFIP, CFQ) or software (CFM).
What is the difference between FODU and ODU?
Full Outdoor Unit (FODU) comprises management controller, modem, multiplexer and radio in one unit, whereas Outdoor Unit (ODU) comprises only radio part and requires Indoor Unit (IDU) for operation.
Where should lightning arrestors be installed? Are lightning arrestors obligatory?
Lightning arrestors are highly recommended for system stability.
The following lightning arrestors are required:
- CFIP 106/108 FODU - power/Ethernet/E1 at user equipment side;
- CFIP Lumina FODU optical - power at user equipment side;
- CFIP Lumina FODU electrical - power at user equipment side, Gigabit Ethernet at FODU and user equipment sides;

In a single link only SAF equipment is interoperable, while outgoing interfaces are compatible with any equipment with appropriate interface support.
What accessories are required for the link apart from antenna and ODU-IDU/FODU?
Accessories may vary depending on a link configuration planned. Common accessories for any configuration are mounting tools, lightning arrestors, power supplies, appropriate interface cables and connectors.
For any further details please contact sales department sales@saftehnika.com
What is the maximum link distance with SAF equipment?
Normally links are installed and used on distances over 5-50 km, though every individual case requires discrete calculation because there are plenty of aspects to take into consideration (required capacity, fade margin, rain/multipath availability, available bandwidth, topography of the region, annual temperature, rain zone, height over sea level, antenna size, etc.). Under favorable conditions distance may be increased up to 150 km, but under unfavorable conditions distance may decrease to 1 km. Please refer to case study examples to assess real world practice
What is the maximum link capacity with SAF equipment?
- CFIP Marathon FIDU - 70Mbps (4+0 with protection switching)
- CFIP-106 FODU - 106Mbps (1+0, 100Eth+4T1)
- CFIP-108 FODU - 108Mbps (1+0, 100Eth+4E1)
- CFIP Lumina FODU - 732Mbps (2+0 with protection switching)
- CFIP PhoeniX split mount - 1160Mbps (4+0 with protection switching, 1000Eth+80E1/T1)
- CFIP PhoeniX M split mount - 1392Mbps (4+0, mixed payload of Ethernet, STM-1, E1)
I think I’ve received damaged/DOA antenna, what should I do?
First of all it is necessary to spot all of the things that could cause the damages and take the pictures of them. The pictures should contain:
- the view of received package, especially the dented or smashed places;
- the view of opened package with an antenna inside;
- the overall view of the antenna with damages;
- the view of the damaged places on the antenna;
- the view of S/N of antenna and the package.
Secondly, need to prepare a list of the damages and their short descriptions. All this data should be summarized and sent to the technical support of SAF Tehnika.
When should I choose single/dual polarized antennas?
In common cases for 1+0 configuration single polarized antennas should be considered. Dual polarized antenna allows to connect 2 ODUs to a single antenna so it can be used for such applications as 2+0 and 1+1 protected frequency diversity as well as for employing XPIC (for instance in CFIP Phoenix M 2+0 XPIC aggregation setup) or MIMO features (for instance Freemile 5 GE MIMO product might be used with external dual-polarized antenna interconnected via 2 coaxial cables).
What antennas do I need to transmit data with SAF radio?
The choice of antenna type/vendor depends on frequency, SAF product type and planned link configuration. Most of SAF products (in frequency range 4 up to 42GHz) require solid parabolic antennas, while CFIP Marathon II product requires grid antennas in 1.4GHz and Yagi antennas in 300MHz application. Depending on planned configuration single or dual polarized parabolic antennas might be used for point-to-point microwave data transmission applications. It is important to consider the flanges on the antenna and SAF radios. The type of flanges should match otherwise adapter or waveguide between the radio and antenna is required. Most of the SAF radios (CFIP/Integra series) starting from 7GHz band have UBR type flanges. Specifically 4/6GHz band radios (CFIP series) and 1.4GHz CFIP Marathon II have N-type connectors, while 17/24GHz band radios (CFIP Lumina and Integra series) have circular 13/10mm flange.
Some vendors provide SAF adapted antennas, so they can be connected directly to SAF radios. Another opportunity is to use waveguide (e.g. UBR-PBR) in between or a coaxial cable (for 4/6GHz CFIP series and 1.4GHz CFIP Marathon II). Before choosing the vendor of antennas it is recommended to get in contact with SAF engineers in order to find out if particular antenna will be compatible with SAF product. Moreover it is recommended to use antennas that have adaptation to SAF products in order to avoid the use of adapters or waveguides.
Can I paint the MW antenna?
There is no restrictions painting the dish of antenna. It is painted with powder coating paint, so it is possible to do all you wish on top of that. For radome - film will be the best (such as Oracal, 3M, etc.), as radome is made of fairly slippery plastic and it is tricky to get good adhesion for paint over plastic. These films are available in any color and some of them guarantees outdoor performance. No penalty in radio signal propagation is expected. For 1.2m antennas and larger the same film probably is the best option, but it's trickier from mechanical perspective, as 1.2m and larger sized antennas radomes are flexible textile with rubbery plastic finish.
Please explain the reasons why one would choose a specific 1+1 diversity configuration over another – that is Frequency over Hot Standby, etc? Is one type of redundancy config “better” than another?
1+1 hot standby is considered as hardware protection only. One ODU transmits per site, the other is in standby mode. If main ODU operation is disturbed, the system will automatically switch over to alternate ODU and remain in operation.
1+1 protected frequency diversity protects hardware and also improves reliability against so called multipath fading phenomena. All ODUs operate at the same time but each ODU pair use separate frequencies. Hence having two frequency pairs, both frequencies are most likely NOT to simultaneously experience the same amount of destructive multipath from reflective atmospheric layers.
1+1 protected space diversity protects hardware and also gains improvement against multipath fading from reflective atmospheric layers AND ground reflections due to vertical spacing between receiving antennas. Space diversity typically is a "must" for very long and over-water paths where water covers significant part of the profile.
Of course, each link should be separately studied to identify the most appropriate configuration to apply.
What is the optimal vertical separation between antennas in 1+1 space diversity configuration for gaining availability improvement?
The recommended vertical spacing between the antennas is 7-14m. An optimal spacing is achieved if the antennas are spaced with at least 200 wavelengths. For example, the wavelength of 7GHz is 0.043m *200=8.6m. Microwave link case studies suggest a considerable diversity improvement is achievable even with 4m spacing.
I need to establish a reliable microwave link over water. Should I be worried about reflections disturbing radio link and do I need to install SAF equipment in 1+1 space diversity configuration?
Whether a SAF link will operate with good reliability over water mainly depends on particular link profile and reflection geometry, which can be analyzed with the help of link planning software. In case the reflective point is located on the water and the surface is large enough to reflect a significant part of first Fresnel zone hitting the receiving antenna, the link will periodically suffer from destructive interference. To counter performance degradation caused by reflections, 1+1 space diversity configuration can be used. Improvement is achieved due to two diversity paths not correlating with each other, which means when one antenna experiences outage, in the same time diversity antenna should receive maximum signal level.
It is possible some links will not experience reflection problems due to profile properties. Also, reflections can be minimized with such techniques as “shielding”, “Hi-Lo” or using high performance antennas. This is to say, some over water links can provide reliable operation without 1+1 diversity schemes. NOTE! Always use vertical polarization for over water links.
What is the correct way of aligning antennas between A and B sites in 1+1 Space Diversity configuration?
1. Set transmitter power ON for the main link (A1 to B1), while the diversity link (A2 to B2) is OFF. Perform the alignment of the main link till you get the maximum Rx level or RSSI reading, then fasten the antennas.
2. Set transmitter power ON for A2 and B1, while B2 is OFF. Align A2 antenna towards B1 to achieve the maximum Rx level and fasten A2 antenna.
3. Set transmitter power ON for A1 and B2, while A2 is OFF. Align B2 antenna towards A1 to achieve the maximum Rx level and fasten B2 antenna.
4. Perform the 1+1 link protection configuration according to the technical documentation.
How close SAF radios can be mounted on the same tower? I have a tower that has very limited space, so is necessary to know what is the minimum suggested mounting distance between radio units?
There are no special requirements or distance restrictions between SAF radios and if necessary they can be installed side by side. However the operating radio frequency interference should be avoided between the units (frequency planning).
What should I consider when designating frequencies for my microwave links and can I re-use the same frequency for two co-located SAF links?
It is strongly recommended to install only same band radios in the same site ("L" with "L" band or "H" with "H" band) to avoid interference in between same site ODUs from the back of the antennas and to avoid overshoot interference at the remote sites. The best scenario is where links have a wide angle in between (close to 180°). In this case you can reuse the same frequency even in the same polarization. Usually antenna front-to-back ratio is sufficient enough to attenuate the interferer signal to a level at which it will not cause interference. In case where you have narrow angle between the "legs" (less than 60°) you can consider these links as very close or even parallel and the frequencies used for these links need to be different (adjacent channel). Also, different polarization implementation can be used to counter interference in such conditions. Enable ATPC (Automatic transmit power control) to decrease overshoot interference transmission during non-faded periods.
How to interconnect outdoor units for a initial link bench test, if I don’t have a special ODU interconnection test suite?
SAF Tehnika always recommends using special ODU test suite consisting of waveguide to coaxial adapters (differing by frequency), attenuators and coaxial cable. However, it is possible to interconnect ODUs installing 4-5 thick books between ODU waveguides to create additional attenuation, but this setup cannot be used for performance measurements such as BER test. NOTE! Do not face powered-on ODUs towards each other without attenuation. You can irreversibly damage ODU internal components.
Is Tx power the main parameter for link budget, distance and link performance quality?
Link budget and performance quality does not depend only on Tx power. It depends also on other parameters like Rx sensitivity (received signal level threshold), antenna sizes etc. Link budget calculation software (e.g. SAF Path Calculator, Pathloss etc.) uses the following parameters for link budget and performance quality calculation: Tx power and Rx threshold values (forming System gain), transmitting frequency, antenna gains, additional losses (couplers, coax cables between ODUs and antennas etc.), atmosphere/path profile characteristics and rain rate. In result we can calculate link availability and link performance quality for planned link. Those results depend on all above mentioned parameters. Note that IF cable (connecting IDU and ODU) attenuation is not used for link budget and availability calculations as it does not carry RF signal.
What is OBU and IBU?
OBU (Outdoor Branching Unit) and IBU (Indoor Branching Unit) can be used to connect multiple radios (ODUs and IRFUs) to a single antenna. OBUs and IBUs contain Tx/Rx filters, circulators and duplexers. So, ODUs and IRFUs which are connected to OBU or IBU do not have their own duplexers. In results such connection scheme offers following advantages:
1) Lower attenuation (longer link distance)
2) Up to 8 ODUs/IRFUs to single antenna
Why is it not possible to achieve the predicted RSL while performing the antenna alignment?
Typically, the target receive signal level in the field is within +/- 3dB of the theoretical value; however, there might be different reasons of not achieving desired RSL during the alignment procedure:
1. Missing the main lobe of the antenna radiation pattern. It is possible that the alignment is performed towards the side lobe of the antenna, and thus reaches about 20dB lower RSL. Both side lobes should be found to make sure the main lobe is finally selected.
2. Alignment is performed towards strong reflected signal. This is the case mainly on the links over the water surface. It is recommended to perform antenna sweep in both: vertical and horizontal planes in order to distinguish useful signal from the reflection.
3. Alignment procedure is complicated due to slow RSL indication refresh times in Web GUI. It is recommended to use a good quality voltmeter in order to read the RSSI values immediately while performing sweeps.
4. Alignment procedure is complicated due to enabled ACM/ATPC functionality. It is recommended to disable ACM/ATPC and to set the lowest modulation to facilitate the alignment process.
More detailed recommendations on alignment are available in Support -> Downloads section of the Website under the Whitepapers subsection.
What are the “shielding” and “Hi-Lo” techniques?
Both techniques are used to mitigate signal degradation caused by multipath.
Shielding implies positioning antenna at a certain distance from the roof edge. This way the natural shield blocking the ground reflections is obtained. Mast’s height vs. distance from the roof edge relation can be selected as 1:2 as a basic rule (or 1:1 when both polarizations are used, e.g. 17/24GHz), meaning that antenna should not be placed further from roof’s edge as its height doubled
A Hi-Lo technique implies increasing antenna mounting height AGL on one side of the link while decreasing on the other. If significant heights difference is obtained between the sides, the reflections miss the receiving antenna propagating above or below it. This is the way how to alter path geometry to decrease the multipath effect.

How is Spectrum Compact used for antenna alignment?
One of the applications where Spectrum Compact can be used is antenna alignment. Spectrum Compact can be connected to the antenna directly and used as the receiver. On the other side of the link, microwave radio will work as the transmitter. Another option is to use Spectrum Generator device as the transmitter on the remote side of the link. During antenna alignment, it is recommended to enable "Maxhold" function to find the main lobe of the signal. When the signal is found and tuned to the highest possible level, Power In Band function can be enabled to observe exact signal Rx level in order to fine-tune the antennas and to reach the calculated Rx level. For more details refer to SAF technical support team at techsupport@saftehnika.com
Can Spectrum Compact be used with any radio system?
Yes, Spectrum Compact can detect signals from any microwave radios in frequencies from 0.3-43 GHz, V-band frequencies and E-band frequencies.
What difference is acceptable between the measured Rx level and the calculated Rx level in order to consider the signal clear?
Common practice is that difference between measured Rx level and calculated RX level shouldn't be more than 1 to 3dB, however, you have to take into account accuracy of Spectrum Compact - for Continuous Wave (CW) signal at temperature 21oC, it is +/-1dB, for all temperature range it is +/-3dB.
For which frequency bands is the Spectrum Compact available?
Spectrum Compact supports following frequency ranges: 0.3-43 GHz, 56-67 GHz (V-band) and 70-87 GHz (E-band). Frequency range 0.3-43 GHz is covered by six Spectrum Compact devices in following frequencies ranges accordingly: 0.3-3 GHz, 2-8 GHz, 6-12 GHz, 10-18 GHz, 17-24.3 GHz, 24-43 GHz.
What is the battery life of Spectrum Compact device?
Battery life of Spectrum Compact device is up to 4 hours (depends on device type). But it is possible to extend it by using power banks.
What is the difference between integrated Integra-G vs. Integra-GS?

What is Power over Ethernet voltage input range? What voltage is going to Integra-G/GS FODU from an injector?
Input voltage range for Integra-G/-GS is 36 to 57V DC. While input voltage range for SAF PoE injector I0ATPI24 (older model - I0ATPI22) is 22..65V DC. In default DC/DC converter mode PoE injector stabilizes output voltage to 54VDC.
Can I use SAF CFIP FODU PoE injectors for Integra-G/GS FODU?
Integra-G/GS requires Gigabit Ethernet PoE injectors. GE injector from CFIP Lumina could be used with Integra, while Fast Ethernet injector from CFIP-106/108 wouldn’t be suitable.
Can we use our own PoE injectors or power directly from a PoE switch?
Integra-G/-GS uses proprietary PoE++ standard, but third-party PoE switch can be used if it complies with IEEE defined PoE specifications and can provide at least 60W load power for 15…42GHz Integra-G/-GS FODUs and 90W load power for 6-13GHz Integra-G/-GS FODUs.
What is the limitation on the cable length for PoE? Can I power-up Integra-G/-GS FODU from 802.3af/at switch?
The maximum Cat 5e or better cable length is 100m including PoE injector (cable length from a user equipment to Integra-G/-GS Ethernet interface). Integra-G/-GS is not 802.3af/at compliant. Integra-G/-GS power consumption is over 30W, and thus 802.3af/at switches wouldn’t be able to provide sufficient amount of power.
What is the power consumption of the Integra-G/-GS radio units?
Integra-G/-GS FODU power consumption is from 31 W to 74W depending on the frequency band, SFP modules connected and Injector type. For more detailed information please refer to the technical specifications in Integra series datasheet.
Can we use any SFPs? Will they be compatible? Are the radios delivered with SFP sockets by default?
Integra-G/-GS radios are equipped with 2 SFP sockets by default.

I have noticed poor overall performance with Integra-WS and bursty traffic. What could be the problem?
Integra-W/WS has limited Ethernet buffer capacity and is very sensitive to the increased Ethernet traffic bursts. Bursty nature of traffic may result in frame discards on the Integra-W/WS radio and, consequently, in decreased throughput. To ensure good performance with bursty Ethernet traffic, it is highly recommended to use Integra-W/WS radio with the external network equipment which implies decent frame buffer size, flow control function with the ability to work only in Rx mode, as well as traffic shaper with configurable egress burst limitation.
