Product Description
HT8500A
Standard Type CATV 1550nm Optical External Transmitter
(47~862MHz, CNR1≥ 53dB, SBS: 13, 16, 18dBm adj. )
Product description
AITC is the well-known manufacture in analog externally modulated optical transmitter in the world. HT8500A, an economical 11550nm Optical External Transmitter is produced specially for middle and small CATV station. Optical transmitter adopts narrow bandwidth (Typ. =1MHz), low noise and continuous wave DFB laser as the light source, adopts CATV special LiNbO3 external modulator to modulate signal, and adopts a series of unique innovation technique to reach the excellent system control. 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. The machine is equipped with perfect RS232 communication interface, SNMP network management and 1+1 backup power supply.
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.
