Hangzhou Daytai ,over 10 years manufacturer on fiber optic field
,offering one-stop solutions products and service ,not just items
showed in this listing ,please send inquiry with your demands and
requirements.★Description 1310nm Direct Modulation Optical
Transmitter With AGC (DT-DMOT-1310-xx dbm) series directly
modulated optical transmitter adopts high-performance DFB laser,
operating in 1310nm frequency range, optical transmitter modulates
headend RF signal into 1310nm wavelength optical signal, and
combines the modulated optical signal to fiber cable, and completes
far distance, large area cover transmission for image, audio and
data. Output optical power:4~31mW is optional,Optical
wavelength:1310±20nm,Optical connector:SC/APC,Optical return
loss:45dB,Frequency range:47~862MHz,RF input
level:80±5dBuV,C/N:51dB,C/CTB:65dB,C/CSO,60dB,dimension:440×370×44(mm),American
standard power supply or European standard power supply is
optional.★Features⊙Push-pull double power supply design, input
voltage range is up to AC110V~265V.⊙Adopts pre-distortion circuit
to improve optical transmitter performance parameters in
further.⊙Adopts high linearity, low noise distributed reaction type
DFB laser with optical isolator as source. ⊙Adopts DFB components
back light monitor and control circuit, to realize optical power
high stability.⊙47~862MHz operation bandwidth, with AGC function,
to realize amplification and automatic optical modulation depth
control.⊙High effective temperature control circuit, to ensure
laser chip temperature in 25±0.5ºC constantly in various
temperature environment.⊙1U standard rack, equipped-in high-bright
displayer in front panel, to display equipment's each operation
status parameters exactly.⊙Installation complies to sort-II network
management transponder, through network management system to
monitor and control equipment's operation status, performance
remotely, to improve network reliability.★SpecificationItems Units
