Specifications

WT1310AGC is a 1310nm direct modulation optical transmitter with high index and AGC function. It adopts high linearity and low chirp DFB laser, builtin predistortion compensation and AGC, APC, ATC closed loop control, which improves the system index obviously. This transmitter enables cost effective optical transmission in the original HFC network and is ideal for any cable system that need to build the Green Field Service.
Summary
1. WT1310 Series field 1310nm laser transmitter is the featured product that we exploited on many years' project practice experience, thoroughly solve the engineering problems that some remote areas can not build indoor machinery room
2. WT-1310 Series field 1310nm laser transmitter adopt high performance water- proof cast Aluminum housing, high reliable switch supply, strict anti-thunder system and build in large power electronic refrigerator , which enable equipment to fit the field environment temperature between -40℃~ to 60℃ and ensure it can work long-time and stably in the field sever environment.
 
Performance Characteristic
◇ Adopt high performance DFB laser with international famous band, narrow Spectrum, good linear and high output power.
◇ Adopts RF power digital automatic process technology designed by ourselves at RF driving part. It can auto-adjust RF driving power according to the input RF signal level and channel number(15~84) to make the C/CSO, C/CTB and C/N in the best condition , which ensure performance of the whole equipment and make the output level of optical receiver keep the same.
Advanced multi-frequency point pre-distortion technology with GaAs devices optimize
◇ C/CTB and C/CSO value, which are the most important index in CATV system, meanwhile maximize the C/N.
◇ The built-in micro-computer automatic monitor circuit can real-timely and precisely monitor various working condition of optical output power and laser to ensure the stable optical output power and prolong the working life of laser effectively.
◇ Builtin large power semiconductor refrigerator, which can enable the equipment to fit the field environment temperature between -40℃ to +60℃..
Adopt high performance water-proof cast Aluminum housing, high reliable switch supply, strict anti-thunder system, which ensure the equipment work long-time and stably under the field severe environment.
