1. Externally modulated technology for HT8500T optic transmitter, no laser chirp, low dispersion distortion, high extinction ratio, with excellent characteristic within 40~862MHz, used in the over-long trunk of large and medium sized cable television head-end.
2. 1+1 powers supply back , up hot-plug function available.
3. Narrow line width (Typ=0.35 MHz), low noise, and DFB continuous wave laser, be propitious to reduce dispersion effect.
4. The operating bandwidth is up to 47~1000MHz.
5. CNR ≥ 53.5dB and excellent CTB, CSO index.
6. SBS: 13~19dBm, continuous adjustable.
7. ITU standard wavelength adjustable , users can adjust and set the wavelength on the front panel with ±0.05nm stepping in the range of ±200GHz (±1.6nm), used in the network upgrading and expansion of WDM system.
8. AGC/MGC mode is optional at spot; OMI can be optimized at spot.
9. Perfect RS232 communicate interface.
10. Advanced SNMP network management function.
11. Casing temperature auto-control.
1. Applied in over-long trunk of central station, transmit RFTV, IF/SAT.Analog digital mixture transmission >200Km (with dispersioncompensation).
2. Pure digital transmission (without dispersion compensation) >400Km(with dispersion compensation) >700Km.
3. Applied in second transmission of sub-station, it can supply somappreciation service of high quality, high reliable RFTV, IF/SAT and IPTVOD for the user in the second-grade service area. Avoid adopting1550nm External Modulation Optical Transmitter to cause the CSOdeterioration and limit the transmission distance of laser chirp.
