Product Description

FTTH CATV Optical Transmitter 1310nm

Product Description

Transmitter series is a practical, high index, multifunctional and short distance transmission products, is the construction of CATV HFC network equipment.

This machine adopts the high linearity, low chirp DFB laser as light source, RF drive part adopts advanced predistortion compensation and closed loop AGC,APC, ATC control, to ensure that the excellent performance, and make the optical receiver output level is constant, various working parameters by the micro processing control, optional SNMP network management software and 1+1 power supply backup, chassis temperature can achieve the automatic control, can be applied to high-end users.

Main Features

Having high-performance DFB laser, this device has narrow spectrum, high linearity as well as high output power stability.
Advanced pre-distortion technique, which effectively improves whole device’s non-linearity performance
Cutting-edge microcomputer auto-monitoring-and-control circuitry, which is able to precisely monitor and control the output power and operating status of the laser, thereby to stabilize output power and improve the life span of the laser.
LCD or VFD display installed on front panel, each real-time operating status parameter can be shown.
Having high-performance switch mode power supplier unit which has perfect over-voltage and over-load protection functions, device’s safe operation over long run is secured.
Standard 19” 1U rack, plus RS485 or Ethernet element management port, remote management is easily realized.
