Optic Relay Station 1310nm

ORS-13-P-23D

Catvision’s ORS Series Optic Relay Station is used, when the optic signal at 1310nm wavelength drops to low level, where it can not be further transmitted. A power-doubler amplifier with built-in AGC circuit is incorporated providing a stable RF signal with excellent C/N, CSO & CTB performance for long haul transmission. These are suitable for both analog and digital Cable TV networks.

Catvision optic relay station incorporate a thermo-electric cooler and auto control for laser power & bias current to ensure stable optic output power and longer life of laser module.

These transmitters can be interfaced with a network management system via a RS232 or RS485 port for status monitoring.
