Product Description
HES-55S
4-Band SAT-IF Overlay
Externally Modulated Optical Satellite Transmitter
Product description
4-Band Sat-If Overlay Optical Satellite Transmitter HES-55S series 1550nm wide band micro-wave external modulation optical transmitter, adopts external modulation technology, without laser chirp, extremely low dispersion distortion, large extinction ratio. It fits for high ratio, high broadband, long distance telecommunication network application.
Product feature
1. Laser APC, ATC, AWC
2. It adopts frequency-division multiplexing (FDM), and can simultaneously transmit 4-way SAT-IF composite signal 4× (950~2150MHz) through one fiber.
3. Can choose ITU-T standard wavelength, adopt DWDM system application.
4. SNMP support remote management and control
Main application
1. Satellite-TV long-distance transmission
2. Satellite-TV FTTH
3. CATV, satellite-TV, Internet, Triple-play
4. Other microwave wideband application.
