Product Description

HES-55A (47~862 & 950~5500MHz )
4-Band SAT-IF & CATV Overlay
Externally Modulated Optical Transmitter

Product description
AITC HES-55A series 1550nm wide band micro-wave external modulation 4-Band satellite CATV optical transmitter, working bandwidth covering range is 47~862 & 950~5500MHz. It can transmit multi (stacker) 4-way SAT-IF signal and CATV signal by a fiber, to realize one satellite-four polarization-4 way SAT-IF signal of 950~5500MHz (or different satellite 4 way SAT-IF signal), and 47~862 MHz CATV signal, all replacement a fiber to transmit. Users can simultaneously receive all full TV contents of satellite video carried and CATV's analog digital TV. It can provide high quality satellite TV and CATV service up to 3000 SDTV or 600 HDTV channel.
HES-55A can compatible with any FTTX PON technology to realize satellite TV, cable TV, internet integration of three networks. It can choose ITU-T standard wavelength to fit for DWDM system application.

Product feature
1. RF operating bandwidth: 47~862 & 950~5500MHz
2. Can use the EDFA, YEDFA, is compatible with any FTTX PON.
3. Reach up to 3000 SDTV or 600 HDTV channels and CATV to use in subscriber end.
4. It adopts frequency-division multiplexing (FDM), and can simultaneously transmit CATV signal and 4-way SAT-IF composite signal 4× (950~2150MHz) through one fiber
