Product Description

HT8000
External Modulated Multi-Port Output 1550 Optic CATV Transmitter

Product description

1.1550nm Optical CATV transmitter
2. With externally modulated
3. SNMP management function option
4. CTB, CSO<=-65, SBS: 13~20dBm

Product features

1. Usinghigh-power, continuous waveDFBlaser, which provides 4-way, 6 way, 8 way, 10way High linearity standard optical power output, can be linked more FTTP EDFA.
2. InnovationSBS: 13 ~ 20dBmadjustable.
3. Telecom class high reliability and network management.
4. High system indicators: CNR≥ 53.5dB\CTB≥ -65dB\CTB≤ -65dB ( Without EDFA ).
5. Externally modulated technical no laser chirp, low dispersiondistortion, large extinction Ratio, 40 ~ 862MHz bandhave good features.
6. Narrow linewidth(Typ. = 0.65MHz), low noise, DFB continuous wavelaser, helps to reduce the dispersion.
7. ITU standard wavelength, in the ± 200GHz (± 1.6nm) range can be adjusted.
8. AGC / MGC mode is optional at spot; OMI can be optimized at spot.
9.1+1 powers supply back, up hot-plug function available
10. Advanced SNMP network management function, perfect RS232 communicate interface...
11. Casing temperature auto-control. ]

Main application
