Optic Transmitter
- Catvision OTU-13 D Series Optic Transmitters use directly modulated DFB
technology for transmission of optic signal at 1310nm wavelength. A powerdoubler
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 transmitters 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.Specification
