HT80001550nm external modulationExternal modulated FTTP Multi-port Output 1550nm optical CATV transmitter( CNR≥53.5dB, SBS:13~20 adjustable,7~862MHz) Product description Huatai HT8000 series, Multi-optical port output externally modulated 1550nm optical CATV transmitter, a research product which is designed for FTTx PON large area and multi-user access. HT8000 Series CATV transmitter, based on the series of unique and innovative chassis, SBS can reach 13 ~ 20dBm adjustable, suitable for high-power EDFA applications. Its highindex, high reliability and excellent cost performance,for largeand medium cities CATV network, to achievelocallarge area, multi-user coverage,providing high performance,high-index access. HT8047 : 4 fiber outputHT8067 : 6 fiber outputHT8085 : 8 fiber outputHT8105 : 10 fiber output Product featuresUsing high-power, continuous wave DFB laser, which provides 4-way, 6 way, 8 way, 10wayhigh linearity standardoptical poweroutput,can belinked more FTTP EDFA.Innovation SBS: 13 ~ 20dBmadjustable.Telecom class high reliability and network management.Externally modulated technical no laser chirp,low dispersiondistortion, large extinction ratio, 40 ~ 862MHz bandhave goodfeatures.Narrow linewidth(Typ. = 0.65MHz),low noise, DFB continuous wavelaser,helps to reduce thedispersion.ITU standard wavelength, in the ± 200GHz (± 1.6nm) range can be adjusted.CNR ≥ 53.5dB,SBS: 13~20dBm continuously adjustable.AGC / MGC mode is optional at spot; OMI can be optimized at spot.1+1 powers supply back , up hot-plug function availableAdvanced SNMP network management function, perfect RS232 communicate interface. ApplicationFTTx PON(FTTH,FTTP)DWDM OpticalCATV systemsvalue-added services. Technical index
