HHTR-1310-LDXX  Return Path Optical Transmitter Series

 Introduction

HHTR-1310-LDXX is a high performance modular product which is meet for the HFC network develop the serial function value added service. excellent performance HFC headend platform and the transmitter can be widely used in Metro HFC Network system. With aid of the techniques of microprocessor and inner bus structure, HHTR-1310-LDXX 1310nm optical transmitter adepts DFB laser diode and provide high performance, wide working bandwidth, high capacity for transmission and low non-linear distortion. The embedded processor monitors the status of DFB laser diode and feedback the data of the diode to the controller of HH03 platform. The intelligent controller makes HH03 module work in a stable and reliable environment. HH03 module has the Predstrotion Circuit to improve CSO and CTB performance. Two types of module are available, Automatic Gain Control(AGC) and Manual Gain Control(MGC). And All of the parameter can be configed by front panel.

 it also requests to have the return feedback image, the data, the voice equisignal as well as the system itself network management equisignal function,

 Characteristics
