FECS/FRCS 30-1000 MHz and 350-2500 MHz series
VHF, UHF signal transmission over optical fibre
Description
These modules allow TV signal transmission in UHF bands over single mode fibre. They can be integrated into the racks ref. FCCS152120 or ref. FCCSx5912S-4TX1FX series (consult us for this last reference)
Specifically designed for remote TV signals, the modules are equipped with F-75Ω access connectors (BNC in option).
The equipment has been specifically designed for:
- Production studios
- Mobile installations
- Antennas connection
- ….
The module operation can be monitored by the chassis equipped with the appropriate firmware.
The chassis supervision access allows through the Ethernet network to:
- Check the operating parameters of the modules.
- Adjust the gains of the input or output stages modules.
- Enable an automatic optical loss correction mode on the receiver.
- ….
Other combinations of gain transmission, optical power, RF performance can be studied on request. CWDM conversion on request.
