Product Description
Guangtai HT9500, just in order to apply to this network technology, due to our own technology develop a new broadband type 1550nm External Modulation Optical Transmitter, through multiplexing the frequency, can enlarge the broadcast CATV available band width from 47~862MHz to 47~2700MHz. Not only it can be used into 47~862MHz of analogue digital video transmission, but also transmit in the IF/SAT of 950~2700MHz. Itprovide a whole set of high quality, low cost of optical trunk transition and FTTB, FTTH solution for mixed of DBS and CATV.
HT9500 adopts low noise, narrow bandwidth, continuous wave laser as light source and American JDS-U LiNbO3 external modulator as signal modulation, due to adopting owned system optimized control technology & using top class parts. All equipment has complete RS232 communication interface, SNMP network management and 1+1 power back up optional, machine temperature control automatically, and it ensures high reliability and cost performance of the whole unit.
HT9520C: dual fiber output, CATV operating wavelength, CNR≥53.5dB, SBS: 13~19dBm adjustable.
HT9520U: dual fiber output, ITU wavelength adjustable, CNR≥53.5dB, SBS, 13~19dBm adjustable.
HT9510C: single fiber output, CATV operating wavelength, CNR≥52dB, SBS: 13dBm.
HT9510U: single fiber output, ITU wavelength adjustable, CNR≥52dB, SBS: 13dBm.
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.
