Detailed Product Description


HT1500B (Without AGC)
1550nm Direct Modulation Optic Transmitter

 

Product description

Huatai HT1500B is a kind of 1550nm direct modulation optical transmitter, standard and without AGC function. It adopts high linearity, low chirp DFB laser, bulid-in pre-distortion compensation and closed loop APC, ATC control, obviously improve the system index. It can be used in full channel singal FTTx (≤10Km), also can be used in DWDM narrow band multiplex as well as IP/QAM.
 
Product feature
*Low chirp, high linearity DFB laser
*Dual module therefore drive, high efficient laser pre-distortion regulate
*Full automatical laser modulation index control, AGC & MGC
*Intuitionistic modulater situation display
*Build-in dual power supply back-up, automatically switch
*Automatically casing temperature control, ensure laser's long life of working
 
Main application
*Sub-headend provide IPTV, VOD value-added service
