4-Band SAT-IF & CATV Overlay
Direct Modulated Optical Transmitter

Product description
AITC HDS-55A series 1550nm wide band micro-wave internal modulation optical transmitter, HDS-55A's 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.
HDS-55A working wavelength can be chosed 1310nm and 1550nm. 1550nm can choose ITU-T standard wavelength to fit for DWDM system application. 1550nm working wavelength can choose EDFA. It can compatible with FTTX PON technology. Realize satellite TV, cable television, internet integration of three networks.

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

Main application
1. CATV and 4-Band Satellite-TV FTTH
2. CATV, satellite-TV, Internet, Triple-play
3. Other 47~862 & 950~5500 MHz microwave wideband application
