GRS-5504, a kind of 4-band SAT -IF O/E converter, which makes the superposed 4 ways SAT-IF signals in the band 950~5450MHz that transmitted by optic signal cleavage overlay and revert to standard VH,VL, HH, HL 4 ways SAT IF signal (SAT-IF) to output. It can connect 4*N satellite multi-channel switch, and then serve for multi-users.

GRS-5504/WD, GRS-5504/WF, can be compatible with any FTTx PON, to realize internet, Full-Band SAT-TV & CATV Triple-ply network and FTTH

GRS-5504 the forepart of the satellite antenna adopt satellite channel overlay LNB, such as TOL32, TWL01.

◉ FTTH for DBS
