IT8000 ( CNR≥53.5dB, SBS:13~20 adjustable) FTTP Multi-port output 1550nm external modulation 47~862MHz
Description
Idealphotonics IT8000
series, Multi-optical port output externally modulated transmitter, a research
product which is designed for FTTx PON large area and multi-user access.
IT8000 series, use high-power , low noise, narrow linewidth, continuous
broadcast, DFB lasers. It can provide 4~10 way high linearity standard optical
power output. It can connect 4~10 units high-power FTTB EDFA( Like Huatai
HA5837-32). AS this product without EDFA, so each optical port can out put up
to :CNR≥53.5dB、CTB≥-65dB、CTB≤-65dB,
the high technical index.
IT8000 Series, based on the series of unique and innovative chassis, SBS can
reach 13 ~ 20dBm adjustable, suitable for high-power EDFA applications..
IT8000 Series, Consummate RS232 communication interface. use 1+1 powers supply
back , up hot-plug function available, avoid power damaged lead system
collapse. Machine equipped RS232 communication interface and SNMP network
management. Installation of all optical port can be on the front panel, and
also can be specified on the rear panel.
Idealphotonics IT8000
series, Multi-optical port output FTTP externally modulated transmitter, Its
highindex, high reliability andexcellent cost performance,for largeand medium
cities CATV network, to achievelocallarge area, multi-user coverage,providing
high performance,high-index access.

Feathure
Using high-power,
continuous wave DFB laser, which provides 4-way, 6 way, 8 way,10 way high linearity
standardoptical poweroutput,can be linked more FTTP EDFA.
Innovation SBS: 13 ~ 20dBm adjustable.Telecom class high reliability and
network management.
High system indicators: CNR≥53.5dB、CTB≥-65dB, CTB≤-65dB (
Without EDFA ).
Externally modulated technical no laser chirp, low dispersion distortion, large
extinction ratio, 40 ~ 862MHz band have good features.narrow
linewidth(Typ.=0.65MHz),low noise, DFB continuous wavelaser,helps to reduce the
dispersion.
ITU standard wavelength, in the ± 200GHz (± 1.6nm) range can be adjusted.
AGC / MGC mode is optional at spot; OMI can be optimized at spot.
1+1 powers supply back , up hot-plug function available
Advanced SNMP network management function, perfect RS232 communicate
interface..
Casing temperature auto-control.
