sat-nms LFTX/RX L-Band Fiber Optical Links
The sat-nms LFRX Optical Receiver and sat-nms LFTX 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 2RU 19" drawers, but are also designed to allow N:1 redundant L-Band Fiber Optical Links.
All modules include RF gain adjustment and extensive monitoring. The chassis also contains 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-nms products.
If you order a redundant configuration, the optical transmitter and receiver chassis communicates via LAN or serial connection with each other.
Applications
- VSAT-Remote, VSAT inclined orbit, VSAT-HUB
- SNG Central Station
- TV-Uplink
- Teleport
Configuration
A common configuration is a 4:1 sub-system for an antenna with 4 LNC's, 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 |
