Product Description

HT8500AC (CATV wavelength)
HT8500AU (ITU wavelength adjustable)
Standard type Externally Modulated Optical Transmitter
(47~862MHz, CNR1≥ 53dB, SBS: 13, 16, 18dBm adj. )

Product Description
HT8500A, an economical 1550nm Externally Modulated Optical Transmitter, is produced specially for middle and small CATV station. Optical transmitter adopts narrow bandwidth (Typ. =1MHz). With 47~862MHz bandwidth, CNR ≥ 53dB, CTB ≤ -65dB, CSO ≤ -65dB, SBS: 13, 16, 18adjustable, Optical transmitter can make CATV network transmit video, audio and data with high performance. HT8500AC optical transmitter: Standard type, dual fiber output CATV work wavelength, 1MHz laser line width, SBS 13, 16dBm adjustable, SNMP network management optional.
HT8500AU optical transmitter: Standard type, dual fiber output ITU wavelength adjustable, 1MHz laser line width, SBS 13, 16dBm adjustable, SNMP network management optional.

Product feature
1. High performance: Externally modulated technology for optical transmitter, no laser chirp, low dispersion distortion, high extinction ratio, with excellent characteristic within 40~862MHz in-band.
2. Narrow bandwidth (Typ. =1MHz), lower noise, DFB continuous wave laser.
3. ITU standard wavelength adjustable, the user can adjust and set the laser 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.
4. AGC/MGC mode is optional at spot.
5. Perfect RS232 communication interface.
6. SNMP network management function optional.
7.1+1 backup power supply optional.
8. Casing temperature auto-control.
9. Excellent P/P ratio.

Main application
1. Used in middle and small CATV center head end
2. Used in second-grade service area of sub-station. Provide second-grade users with high quality and high reliability value added service such as RFTV, IPTV, VOD and so on.
