Catv Cable Optical transmitter For HFC Network

Usage:

This series of optical transmitters are applied for digital signal transmission of image and date in the field of catv and communications industry.

Function characteristics:

1. Adopting original inported DFB laser with excellent high linearity, optical isolation, thermoelectric cooler

2. two RF input interface to input signal: meeting the simulation, figures input separately and local input requirement.

3. RS-232 computer interface and two RS 485 industrial standard interface are available for managing

and monitoring local and long distance network.

4. Adopting 1U19” standard dimensions.

5.Work temperature ATC and power APC adopt microprocessor auto control, which makes DFB laser have excellent working performance, accuately controling output optical power, prolonging service life

6. Excellent switch power to suit for voltage in AC110-260V.

7.4 function modules: RF processing unit, laser DBF, control and warning protection circuit and power module.
