Product Description
Quattro/Quad LNB Satellite TV Fiber Link GLB3500-4
Direct Broadcasting Satellite (DBS) and Direct to Home (DTH) are the most popular way to enjoy satellite TV worldwide. To do it, a satellite dish with LNB, coaxial cable, splitter or multi-switch and satellite receiver are necessary. However, satellite TV might be difficult to the subscribers living in the apartments due to bad antenna location or high coaxial cable signal loss. Fiber cable has more bandwidth and much less loss than coaxial cable. With fiber cable, satellite master antenna TV RF signal can be delivered to 30Km far away or distributed to 32 apartments directly, to 320 or 3200 or 32000 apartments via GWA3530 fiber optic amplifier.
GLB3500-4 satellite RF fiber link includes GLB3500-4T optical transmitter and GLB3500-4R optical receiver. GLB3500-4T converts Quattro LNB (VL, HL, VH and HH) four 950~2150MHz bands and one Terrestrial Digital TV RF into 1550nm laser to fiber, while GLB3500-4R converts optical signal back to four 950~2150MHz bands and one terrestrial TV RF. The optical receiver acts as a virtual Quattro LNB, offering satellite and terrestrial signals to sat multi-switch and sat receivers.
