1 Introduction
The sat-nms LFTXRX fibre optical link is a high performance transmission system which transmits
a complete frequency band, with all its separate carriers, over a single mode fibre with length up
to 5km. The big advantages of fibre optical links are:
Lightning protection
Fully isolated between the two destinations
No ground loops
bug proof
Two types of optical converters are available
sat-nms LFTX --- optical transmitter which converts from IF input spectrum to optical output
at 1310nm
sat-nms LFRX --- optical receiver which regenerates the optical signal back to an IF
spectrum
SatService offer the LFTXRX modules for different frequency bands.
sat-nms LFRX-L and LFTX-L --- 950 to 2150MHz
sat-nms LFRX-B and LFTX-B --- 50 to 2150MHz
sat-nms LFRX-10 and LFTX-10 --- 950 to 2150MHz and 10MHz reference frequency for
BUC
sat-nms LFRXO10 and LFTXO10 --- 10MHz only
Additional there are optional modules available which will be supported by the software and the
backplane
sat-nms LFSW --- RF-Transfer Switsch which allowes to build redundancy paths with the
optical link
sat-nms TBD --- More modules are possible, please define your request

2 Installation
This chapter describes how to install the sat-nms LFTXRX Fibre Optical Link. You find a guide
how to connect, configure and mechanically mount the equipment below.
Before you start, please first read the Safety Instructions chapter below. It contains some
important recommendations to prevent damage from the equipment.
Then, we strongly recommend to do a first setup of the unit on a lab desk before installing it at it's
final location. This is mainly for the following reason:
1. To setup the IP parameters, the PC used for configuring and the chassis must either be
connected to the same Ethernet hub / switch or must be connected directly with a crossover
cable. The initialization program does not work through routers intelligent or network
switches.
Hence, the typical sequence of tasks when putting an sat-nms LFTXRX into operation is as
follows:
1. Read the chapter Safety Instructions
2. Set the unit's IP address
3. Mechanically installation of the chassis
4. Connecting the LFTXRX
5. Configuring the LFTXRX
2.1 Safety Instructions
Failure to observe all Warnings and Cautions may result in personnel injury and/or equipment
damage not covered by the warranty.
The equipment described in this manual is designed to be installed and used by
properly trained personnel only!
ATTENTION inv isible Optical Radiation! If connected to a
power supply, the unit provides invisible Laser-radiation. The source is class 3R Laser diode
as defined in DIN EN 60825-1:2001-11. P0=2mW, Lambda=1310nm.
Never look into fibre-optical components like connectors or fibres. Use an infrared
viewer, optical power meter or fluorescent screen for optical output verification.
Do not allow any dirt or foreign material to get into the optical connector bulkheads. This
(C) 2021, SatService GmbH www.satnms.com LF20-UM-2107 Page 6/43

may cause damage to the polished optical connector end faces
Follow standard Electrostatic Discharge (ESD) procedures when handling a the chassis and
the modules of the LFTXRX.
The ground terminal of the device has to be permanently connected to a grounding point for
save operation. Otherwise, the device could be damaged.
The power supplies are EMI filtered. The chassis is connected to earth ground in compliance
with safety requirements. Always use the 3-prong AC plug with earth ground to avoid
possibility of electrical shock hazard to personnel.
Select and apply the appropriate 100-240AC voltage according to the data sheet and
documentation before connecting power.
Install suitable overvoltage protection to ensure that no overvoltage (such as that caused by
a bolt of lightning) or overcurrent can reach the product. Otherwise, the person operating
the product will be exposed to the danger of an electric shock.
Depending on configuration, the chassis is equipped with user-changeable power supplies.
Always disconnect the mains of the power supply that has to be changed. Wait at least 10s
after disconnecting the mains (for internal discharge of the power supply) before removing
the power supplyATTENTION: To avoid the possibility of an electrical shock, never handle
with a power supply that is connected to mains!
Before you connect the LFTXRX to an L-Band distributor or LNC , please make sure that the
unit to which you connect can handle 15V D/C voltage on its RF L-Band input. Some L-Band
IF distribution equipment does not have D/C blocks included and the unit could be damaged.
If you are not sure how the interfacing equipment will behave, switch off the LNC supply
voltage in the Setup menu or in case of local controlling by hardware switch before you
connect the cable.
The LFTXRX can be damaged if the total RF input power is higher than +10dBm specified
maximum value. Do not connect equipment where the total output power is higher than the
specified value of the data sheet or indicated on the LFTXRX unit.
In case of a failure do not open the sat-nms LFTXRX, you will loose warranty, call SatService
GmbH for a RMA number.
Observe normal safety precautions when operating, servicing, and troubleshooting this
equipment.
Take standard safety precautions with hand and/or power tools.
When connecting the units fault relay circuits, observe the maximum ratings: 48V D/C
300mA, 48V A/C 500mA.
2.2 Handling instructions for optical connectors
Do not allow any kind of dust or dirt on the fibre.
Do not touch the fibre! Otherwise you will get optical attenuation and the opposite fibre in the
corresponding connector will be contaminated as well.
When installing or changing optical connections, ensure that the environment of the room
where the unit is installed is as dust-free as possible.
If you install the unit on-site, make sure that the complete work that causes dust (e.g.
plastering or concreting) is already finished and the resulted dust is cleaned up properly.
Remove the fibre protection cap of the E2000 or FC/APC connectors just before you
connect the optical connector.
Store the protection caps in a closable box that is absolutely dirt- and dust-free.
After disconnecting a fibre, put a dirt- and dust-free protection cap into the connector in
order to avoid dust contamination.
Before connecting, we strongly recommend to clean the fibre. We recommend to use clean
(C) 2021, SatService GmbH www.satnms.com LF20-UM-2107 Page 7/43

compressed air spray like e.g. 'Kontakt 334' or a special cleaning device like e.g. 'CLETOP'
or 'one click cleaner'. Do not use compressed air produced by a standard air compressor,
this air is not clean enough! If a dirty fibre (e.g. contaminated with dust) is connected to a
LFRX or LFTX card, the internal fibre of the LFTX or LFRX card will be contaminated as well
and you will get optical attenuation. In the worst case, the fibre-end might be irreparably
damaged and has to be replaced.You always have to consider: optical attenuation
causes a twice RF-signal attenuation! So e.g. an optical attenuation of 2dB causes 4dB
RF signal attenuation.
2.3 Setting the IP Address
Before you can operate the sat-nms LFTXRX Optical Link, you need to set the unit's IP address.
There is a special configuration program on the documentation CD shipping with the unit for this
purpose. We recommend to configure LFTXRX' TCP/IP settings before you install chassis at it's
final place. To configure LFTXRX, the following equipment is required:
The sat-nms LFTXRX L-Band Optical Link itself
110-240V A/C power
A Computer running a Microsoft Windows operating system equipped with CD-ROM drive
and Ethernet network card.
A CAT5 crossover network cable or a Ethernet hub/switch and standard network cables to
connect the LFTXRX and the computer.
The CD-ROM shipping with the sat-nms LFTXRX.
Setting the chassis' IP parameters now is easily done within a few minutes.
1. First install a network cable between the LFTXRX chassis and your computer. If you have a
crossover cable available, this is very easy: simply put the cable into the network connectors
of computer and LFTXRX chassis. Without a crossover cable, you need to connect both, the
computer and LFTXRX chassis to the same network hub or switch using two standard
network cables. It is essential, that the computer and the LFTXRX chassis are connected to
the same network segment, the configuration program is not able to find the LFTXRX chassis
through routers or network switches.
2. Now power on your computer and connect LFTXRX chassis to the 110-240V A/C supply.
3. Insert the CD-ROM into the computer's drive and inspect it's contents through the 'My
Computer' icon on your desktop. Double-click to the 'ChipTool.exe' program in the 'ChipTool'
directory.
4. When the ChipTool program is running, type CTRL+F to make the program search the
LFTXRX. The program shows a list containing at least one entry describing the actual
network parameters of the LFTXRX.
(C) 2021, SatService GmbH www.satnms.com LF20-UM-2107 Page 8/43

5. The serial number shown in the first column of the list, must match the serial number printed
on the processor's enclosure. If the list stays empty, the LFTXRX chassis is not connected
properly. If there are more entries in the list, the configuration program has found other
devices in this network segment which use the same technology.
6. Now type CTRL+I to open the IP configuration window of the program. In this form enter the
processor's serial number, it's new IP address and network mask. If the LFTXRX later shall
be operated through a router, enter the address of the router on the gateway field, otherwise
leave this field blanc. Be sure, that the 'DHCP' mark is unchecked. Finally click to the 'Yes'
button to set the new parameters at the LFTXRX chassis.
Now the IP configuration of the chassis is completed. You may finally want to test if the LFTXRX
chassis is reachable now. Start your web browser and type the chassis' IP address into the URL
field of the browser. The LFTXRX should reply with it's main page, provided that the chassis and
your computer are configured for the same subnet.
2.4 Mechanical installation
The sat-nms LFTXRX enclosure is a standard 3HU 19" rack-mountable enclosure. Use slide bars
to install the chassis, because the mounting angles will not be able to hold the chassis in the
horizontal position. Fix the enclosure with 4 according screws to a 19" Rack. Don't forget to
connect the "GND"-screw to the Rack.
To ensure sufficient airflow for cooling the unit, we recommend to keep 1RU free space below and
