GRS-5544|Zhejiang GT Lasers Tech. Co., Ltd.

GRS-5544, 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), and then pass by the built-in 4*4 satellite switch to output 4 way full-channel direct broadcasting satellite TV, and then serve for users.
GRS-5544/WD, GRS-5544/WF, can be compatible with any FTTx PON, to realize internet, Full-Band SAT-TV & CATV Triple-ply network and FTTH
GRS-5544 the forepart of the satellite antenna adopt satellite channel overlay LNB, such as TOL32, TWL01.

◉ Adopt one fiber to transmit 4 ways polarization SAT-IF signal well

◉ HRS5544 (built-in 4*4 satellite switch)

◉ FTTH for DBS

◉ Triple-ply Overlay DVB-S

◉ 4 SAT - IF overlay/ cleavage overlay optical fiber links
