Product description: External technology laser working with direct
current, has no laser chirp. It has advantage of no chromatic
dispersion distortion, large extinction ratio, high speed and
disanvantage of high cost, high difficulty in producing. Direct
modulate will lead to high laser chirp (laser's bias current will
be modulated by signal, opercal effect will occur high distortion
in ***0nm. This kind of distortion will become more serious
companied with the increase of transmission distance, bandwidth and
chnnel number. At present, internationally, high feature ***0nm
direct modulate has no obvions feature inferior, when transmit a
analog and digital moltiplex full channel signal, transmission
distance≤*0Km or digital load with transmission distance≤*0Km.
Huatai HT***0B is a kind of ***0nm direct modulate optical
transmitter, standard and without 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 (≤*0Km), 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 <*0Km. Pure digital load <*0Km.
DWDM narrow band multiplex >*0Km.
