Satellite TV & Analog TV 1550nm Optical Transmitter (HES-26A)

Product Description

HES-26A
47~862MHz & 950~2600MHz
Satellite TV & Analog TV 1550nm Optical Transmitter

Product Description
AITC HES-26A series external modulation 1550nm optical transmitter can transmit 47~862MHz and 950~2600MHz analogue signal and digital signal via one single fiber by frequency division multiplexing. It is compatible with any FTTX PON technology, and provides a complete set of high quality low cost fiber trunk transmission and fiber to the building (FTTB), fiber to the house (FTTH) solution for the direct broadcast satellite TV (DBS) and cable analogue TV (CATV) fusion.

Product features
1. Narrow linewidth (<1MHz), low noise, DFB continuous wave laser, be propitious to reduce dispersion.
2. High index: Unique innovative technology, provide excellent CNR, CTB, CSO, SBS.
3. High bandwidth: Contemporary transmit Analog TV, DVB-C and DVB-S.
4. Chassis temperature auto control.
5. Perfect RS232 communicate interface and SNMP network management.
6.1+1 power back-up.

Main application
1. Apply to the extra-long trunk of the central office to transmit analogue and digital TV signal and IF/SAT.
Analogue / digital mixed transmission > 200Km (with dispersion compensation).
Pure digital transmission (without dispersion compensation) > 400Km, (dispersion compensation) > 700Km.

2. Apply to sub-office (sub-head end), providing value-added service like high quality analogue and digital TV, satellite direct TV, also the IPTV and VOD to the users in secondary service area, avoid CSO deterioration and distance limitation caused by the laser chirp when adopting 1550nm direct modulation optical transmitter
