Product description
Huatai HT1500A is a kind of 1550nm direct modulation optical transmitter, standard and AGC function. It adopts high lineaity, low chirp DFB laser, bulid-in pre-distortion compensation and closed loop AGC, APC, ATC control, obviously improve the system index. It can be used in full channel singal FTTx (¡Ü10Km), also can be used in DWDM narrow band multiplex as well as IP/QAM.
Product feature
· Low chirp, high linearity DFB laser, chirp compensation.
· 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.
Analog digital mixed transmit <15Km.
Pure digital load <40Km.
· DWDM narrow band multiplex >70Km.
