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

(47~862 & 950~5500MHz)

Model: HES-55A

Product description:

HES-55A 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.

HES-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.
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.

HES-55A adopts low noise, narrow band, continuous wave laser as optical source, it adopts high bandwidth LiNbo3 external modulator as signal to eliminate 1550 nmlaser to control the chirp. Excellent laser APC, ATC control and external modulation bias control，perfect SNMP, RS232 interface, 1+1 power supply backup. High performance, high reliability and excellent performance price ratio. It is the best choice for subscribers.
