Product description
Huatai HT8500T, top type externally modulated optic transmitter with it's high index, high reliability and excellent cost performance, is applicable for the over-long trunk of large and middle CATV station head-end, WDM system and CFG dispersion compensation system.Product features
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.1+1 powers supply back , up hot-plug function available.Narrow line width (Typ=0.3 MHz), low noise, and DFB continuous wave laser, be propitious to reduce dispersion effect.The work bandwidth for HT8500T optic transmitter is up to 47~862MHz.CNR ≥ 54dB and excellent CTB, CSO index.SBS: 13~19dBm, continuous adjustable.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.AGC/MGC mode is optional at spot; OMI can be optimized at spot.Perfect RS232 communicate interface.Advanced SNMP network management function.Casing temperature auto-control. Main application Used in the over-long trunk and distribution net in the large and middle cable television central station head-end.Analogue digital hybrid transmission > 200Km (with dispersion compensation).
Pure digital transmission (Without dispersion compensation) > 400Km, (With dispersion compensation) >700Km.
