GRS-6805, a kind of high performance 4-band SAT -IF O/E converter which is compatible with CATV (include DAB, DTT, FM). It adopts the technology of frequency division multiplexing, can receive the 950~5450MHz (4 SAT-IF overlay) and 47~862MHz (CATV) optical signal that transmitted by one fiber.
GRS-6805/WD, GRS-6805/WF, can be compatible with any FTTx PON, to realize internet, Full-Band SAT-TV & CATV Triple-ply network and FTTH
GRS-6805 the forepart of the satellite antenna adopt satellite full-channel overlay LNB, such as TOL32, TWL01 and HDS-55A optical transmitter
1. Adopt one fiber to transmit Full-channels direct-broadcast satellite TV and CATV signal with high quality
1. GRS-6805 (Can connect 5*N multi-way satellite switch, and serve for multi-users)
1. FTTH for DBS
2. Triple-play Overlay DVB-S
3. 4 SAT - IF overlay/ cleavage overlay optical fiber links
