sat-nms L-Band Fibre Optical Links LFRX / LFTX
The sat-nms LFRX Optical Receiver and
sat-nms LFRX Optical Transmitter together form a high
performance optical link for analog multi-carrier RF transportation on fibre optical media. They are
available as stand alone modules, integrated in 2HU 19” drawers, but are also designed to allow N:1
redundant L-Band optical
links.
Configurations
A common configuration is a 4:1 sub-system for an antenna with 4 LNCs, with an additional redundant chain.
But the modules can be delivered also in other configurations:
| Column 1 | Column 2 |
|---|---|
| 1:1 | 1:1 |
| 2:1 | 2:1 |
| 3:1 | 3:1 |
| 4:1 | 4:1 |
| up to 10 non-redundant optical links | |
All modules include RF gain adjustment and extensive monitoring. The optical receiver 19" drawer also provides a LCD display and keyboard for local M&C. The remote M&C interface is via web browser, HTTP GET functions and RS232 interface as in all other sat-nmsproducts. If you order a redundant configuration the optical transmitter and receiver chassis communicates via LAN with each other.
The sat-nms optical link receive and transmit modules fit also seamless into the sat-nms LSM switch matrix and add there optical interfaces instead of coaxial interfaces.
