• An additional grounding is possible by the use of a Faston plug (left side of the IDU). Use a 6 mm2 section cable (minimum length required).
NOTE: When more than one IDU are to be mounted in the rack, it is recommended to keep a gap of 1 unit between two IDUs.
1.4 - Antenna Installation
Three types of antenna with several diameters are available for SAGEM LINK F radios.
• Integrated antenna with Sagem Link F ODU interface (0.3m, 0.6m, 0.9m, 1.2m or 1.8m
diameter). With these antennas, the ODU is directly attached on the antenna. In some protected configuration using a coupler, the coupler is attached to the antenna, and the ODU are attached on the coupler.
• External antenna with standard rectangular waveguide flange, which is connected to the
SAGEM LINK F ODU with a flex guide.
• External antenna with two access (dual polarized antenna) connected by two flex guides to the
ODUs.
Antennas models depend on the frequency bands :
• 7 GHz → 7.1 - 7.7 GHz
• 8 GHz → 8.025 - 8.5 GHz
• 13 GHz → 12.75 - 13.25 GHz
Page 9/142 Issue 04 : July 2005
Reproduction and communication prohibited without the written permission of Sagem Communication
• 15 GHz → 14.4 - 15.35 GHz
• 18 GHz → 17.7 - 19.7 GHz
• 23 GHz → 21.2 - 23.6 GHz
• 26 GHz → 24.5 - 26.5 GHz
• 38 GHz → 37 - 39.5 GHz
Alternative antennas to those specified by Sagem may be used, but they must meet the following requirements
• Minimum gain to achieve adequate link margin,
• Radiation Pattern Envelope compliant to the network and country regulations
• Mechanical characteristics to meet specific site requirements (wind and frost resistance)
NOTE: With some antennas, the manufacturer’s guarantee applies only if the antenna feed is
pressurized. Therefore, it is essential to observe the recommendations relative to the selected antenna type. Provision must therefore be made for:
y
installation and connection of a pressurizing system if the antenna is connected to the ODU with a waveguide;
y
use pressurization windows and seals to protect waveguide connections.
1.4.1- Antenna Mount
In most cases, the antenna mounts provided by antenna manufacturers fit on tubular poles (diameter 88.9 to 114 mm).
If the antenna is installed on towers using another type of structure (e.g., square-section tower), special mounting kits must be used for this support.
The following precautions must always be taken :
- Allow enough clearance (± 10°) about the alignment axis. Leave also adequate space around the ODU to allow easy mounting.
- make sure that nothing may obstruct the link, even partially, especially in the near field of view,
- keep enough room for access to the antenna and ODU (for set-up and maintenance measurements),
- install proper lightning rod and earthing,
Note: If there is an existing lightning rod, make sure that the ODU installation site is covered by
the lightning protection cone.
- misalignment under extreme weather conditions must not exceed ± 20 min angle in elevation and azimuth.
The antenna mount may be secured in different ways depending on the antenna installation site type and environment :
- mounting pole secured to the HEA section with a back-plate or clips,
- mounting pole secured to a square-shaped base plate with threaded rods. The base plate is set on top of a resilient plate which may be installed on the terrace of a building without affecting water-tightness,
- wall-mounted staff on the building front,
Page 10/142 Issue 04 : July 2005
Reproduction and communication prohibited without the written permission of Sagem Communication
- antenna mount secured directly to a tower tube (diameter 88.9 or 114 mm),
- antenna support secured to a square-section tower tube with adapters.
1.4.2 - Typical Antenna Installation
Refer to the antenna manufacturer procedures.
1.5 - Installing the ODU(s)
Depending on the configuration, and on the antenna type, there are several ODU mounting possibilities :
• 1+0 Configuration with integrated antenna : (or 1+1 configuration with two antennas) The ODU is directly attached on an integrated antenna with four latches. It is connected to the IDU by a single coaxial cable terminated with N male connectors.
Figure 1.2 - SAGEM LINK F ODU with an Integrated Antenna
Setting the Polarization :
If antenna has a circular waveguide interface (7 GHz, 8 GHz or 38 GHz), polarization depends only on the ODU position. For vertical polarization, make sure that the arrow on the ODU cover is vertical, for horizontal polarization, turn the ODU from 90 degrees.

Horizontal PolarizationVertical Polarization
Figure 1.3 – Polarization Setting for the ODU
If antenna has a rectangular waveguide interface (13 GHz, 15 GHz, 18 GHz, 23 GHz and 26 GHz), then polarization depends on the antenna source position. Note that ODU waveguide output must always be in the same position compared to antenna waveguide input. For vertical polarization, turn antenna source in order to have the large side of the waveguide in horizontal position according to antenna manufacturer procedure. Install the ODU accordingly For horizontal polarization turn antenna source to have the large side of the waveguide in vertical position. Turn also the ODU in order to have coincidence between ODU and antenna waveguides.
• 1+0 Configuration with remote mount and standard antenna : In case of the use of a standard antenna (i.e. large antenna without SAGEM LINK F ODU interface), the ODU is mounted on a pole with a remote mount and connected to the antenna with a standard rectangular flex guide.
Polarization depends on the antenna source position (vertical polarization is obtained when the big side of the antenna waveguide flange is horizontal).

• 1+1 Configuration with a Coupler and an Integrated Antenna : The coupler is attached on the integrated antenna with four bolts. Two ODUs are mounted vertically on the coupler with four latches. Each ODU is connected to its modem by a coaxial cable. As in most cases the coupler is not symmetrical, it is important to identify which ODU is connected to the main position, and which ODU is connected to protection (standby) position. The main and standby ODU positions are indicated on the coupler.
Whatever the polarization is, 1+1 the coupler is always mounted in the same position. There are two types of coupler :
- Andrew coupler : for this type of coupler the arrow on the ODU cover must be vertical
- Filtel coupler : for this type of coupler, the arrow on the ODU cover must be horizontal.

Polarization setting :
- Coupler : ODUs are mounted vertically on the coupler. Depending on the coupler type the arrow on the ODU cover must be horizontal (Filtel) or vertical (Andrew).
- The polarization can be adjusted from turning the coupler polarizer from 90 degrees (Andrew) or by replacing polarizer (Filtel). Refer to coupler supplier instructions.
- Antenna : If the antenna has a rectangular waveguide interface, rotate antenna source to have the wanted polarization. Make sure that polarizations are the same for the antenna and for the coupler.

• 1+1 Configuration with a Coupler Remote Mounted and a Standard Antenna : The coupler is attached on the remote mount and connected to the standard antenna by a flex guide. The two ODUs are vertically mounted on the coupler, with the arrows in vertical (Andrew) or horizontal position (Filtel). Each ODU is connected to the IDU with a coaxial cable.
Page 16/142 Issue 04 : July 2005
Reproduction and communication prohibited without the written permission of Sagem Communication
Polarization setting is done by turning antenna source.
As coupler is not symmetrical in most cases, it is important to identify main position (lowest insertion loss) and standby position.
It is also necessary to identify ODU cables (main or standby) with a label.
• 1+1 Frequency Diversity Configuration with Remote Mounts and a Dual Polarized Antenna : In this configuration each ODU is remote mounted on a pole, and is connected to an antenna access with a flex guide. It is important to identify ODU cables for the one which is on vertical polarization (main), and the one which is horizontal polarization (standby).
1.6 - Installing the IDU to ODU Coaxial Cable(s)
Recommended cables coaxial cables are Belden 9914 and Andrew LDF4-50A. If an other type of cable is used, make sure it is compatible with outdoor use. This cable should be double or triple shielded. Cable impedance is 50 Ohm, and is terminated by two N male connectors.
N connectors must be compatible with the cable, and connector mounting procedure must follow connector manufacturer recommendations.
Install one cable in a 1+0 system or two cables in a 1+1 system.
It is very important to protect N connectors against water : wrap Isolation tape (15 cm) over the coax cover. Start winding from coax cover with one half overlap with each winding in order to protect completely connection from rain action. Press with fingers the tape and make sure the protection is correct.
NOTE: Cables must be installed in compliance with national and local regulations and meet the
specific requirements of the installation site. Some precautions are necessary when installing the equipment on unprotected places (e.g., antenna towers, building terraces, etc.) to prevent equipment from damage by lightning.
In a 1+1 system when two cables are installed, it is very important to identify main cable and standby cable. If the cables are not labeled, it is necessary to perform a resistance check to identify each cable. Disconnect N connectors from IDU, and short circuit one of the N connector on the ODU side (while the other one is open), and measure cable resistance on the IDU side. The lowest resistance corresponds to the short circuited cable. Put labels on both sides of the cables. Remove the short circuit, make sure connectors are clean and dry, and connect proper cable to each ODU.
Cable Grounding
It is necessary to ground properly ODU to IDU cable for a good lightning protection. For this purpose, a cable grounding kit is provided as an option.
Page 17/142 Issue 04 : July 2005

Figure 1.9 : SAGEM-LINK F Grounding Kit
The number of necessary grounding points depends on the site, and on the cable length. Normally, a good protection is achieved with :
• A grounding kit on the cable close to the ODU
• A grounding kit on the cable at the building entrance
• A grounding kit on the cable at the bottom of the pylon
• A grounding kit each 50 meters for long cables.

1.7 - Powering Up the System
Before powering up the Sagem Link F terminal, check that :
IDU and ODU and cables are properly grounded
IDU and ODU are connected together with right coaxial cable(s). in 1+1 operation, main and
standby cables have been previously identified and connected to the main and standby IDU cable interfaces

Plug DC connector into IDU connector. If the terminal is a 1+0 system, switch on the terminal
with the switch in front panel. If the terminal is a 1+1 system, switch on both switches.
The green LED(s) labeled "Power" should be lit.
Connect a PC on IDU front panel DB9 connector Labeled "PC" and run the Sagem Link F Pilot
software
Verify and change if necessary, terminal local parameters (refer to Sagem Link Pilot
description in chapter 4) :
- Transmit frequency,
- capacity,
- modulation,
- transmit power
- Link ID Code
- ATPC must be in the "Off" position at that time
Unless the link is already operating (remote parameters are displayed on the right side of the
main screen of the Pilot software), make sure local terminal parameters are in accordance with far end terminal parameters. (Frequency, capacity, modulation, and Link ID Code must match)
If remote terminal parameters are good and if the main screen displays a "No Remote Radio"
message, it means antennas are not properly aligned.

1.8 - Aligning the Antennas
Antenna alignment is performed with both terminals operating, in normal weather conditions. The receive signal level (RSL) voltage is available on the ODU BNC connector.
A typical RSL curve at ODU access is given on Figure 1.12 The highest the RSL voltage is, the highest is the receive signal level.

Figure 1.12 : Typical SAGEM LINK F Receive Signal Level Voltage
Note : RSL is measured at ODU antenna port. In some 1+1 systems involving a coupler or a remote mount antenna, it is necessary to take in account branching losses to know the actual power at antenna access.
Optimal performance is done when main antenna lobe is aligned with the center of the remote end antenna. It is important to identify main lobe antenna, by rotating the antenna to have the maximum RSL voltage. Note there is around 25 dB difference between side lobes and main lobes (1.5 V).
Good Alignment

Bad Alignment
Figure 1.13 : Antenna Alignment
The expected receive signal level has previously being determined and depends on frequency, remote transmit power, local and remote antenna gains, and length hop. Use the following procedure successively on both ends of the link to align the antenna :
1- Make sure remote transmit power is set in order to avoid overload at receive input (i.e. RSL
less than –20 dBm).
2- Verify that remote terminal is operational
3- Remove the cap on the local ODU BNC connector and connect a voltmeter.
4- Rotate slowly the antenna in the azimuth direction (horizontal) and find the maximum voltage.
If the voltage is around 4.5V (-20 dBm), then diminish the remote transmit power in order to be in a more linear region.
5- Rotate slowly the antenna in the elevation direction (vertical) until the voltage is maximum.
Record the measured voltage.
6- When maximum voltage has been found, tighten all fasteners, verify that the voltage has not
changed. Replace protective cap on the BNC connector.
7- Compare expected receive level with current receive level. If the difference between expected
and actual receive is more than 5 dB, then it should be necessary to optimize again antenna alignment, or to check again if polarization is the same on both ends of the link.
Connect a laptop computer to the PC connector and run the Sagem Link F Pilot software. Normally, the link should be established (no "NO REMOTE RADIO" message displayed). The main screen should be like that :
Page 22/142 Issue 04 : July 2005
Reproduction and communication prohibited without the written permission of Sagem Communication
Receive Signal Levels should be similar on both ends If there is more than 5 dB difference (with the same transmit output power), check antenna alignment, ODUs, IDUs, and antennas.

E1 Tributaries Connections
The four DB25 connectors in IDU front panel correspond to four x 4 Input/output 2 Mbit/s access (E1).
When Ethernet option is installed, additional E1 tributaries can be used along with Ethernet interface. Refer to chapter 6 for more information. Depending on configuration, up to 8 E1 tributaries can be combined with Ethernet transmission. If the configuration with Ethernet option corresponds to a 28 MHz channel in QPSK mode, or to a 14 MHz in 16QAM mode, then an extra E1 tributary is available. Note that this particular tributary is not available for all other cases.
Tributary access are available in 120 Ω balanced mode, or in 75 Ω unbalanced mode. Impedance mode is controlled by the Pilot software. It is possible to have one connector configured in balanced mode, while the others are configured in unbalanced mode. It is not possible to have on the same DB25 connector two tributaries in a different mode.
Tributary connector pinout corresponding to tributaries 1 to 4 is given in Figure 1.20. The other tributary connectors have the same pinout.
When Ethernet option is present and when the data rate corresponds to a 28 MHz channel in QPSK mode, or to a 14 MHz in 16QAM mode, the extra tributary is available on the third connector (Pinout equivalent as trib #1, the other pins are not connected)
