Optic Transmitter 1310nm (Butterfly Laser)

1310nm Transmitters

Catvision OTU-13 Series Optic Transmitters use directly modulated DFB technology for transmission of optic signal at 1310nm wavelength. 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 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.

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