Product Description

GLB3500E-4R satellite TV FTTH Optical LNB yog ob-core fiber ntau input optic receiver, converting plaub wideband RFs los ntawm ob satellites (xws li, Nilesat thiab Arabsat) tshaj fiber signals rau hauv ib tug RF tso zis rau txog li 4 satellite receivers nyob rau hauv ib lub tsev. Ua hauj lwm nrog 2pcs Greatway GLB3500E-2T satellite TV optical transmitters los ntawm ob fiber ntau inputs, GLB3500E-4R muaj built-in SatCR module hloov lub wideband RF los ntawm ob satellites, outputs 4 satellite neeg siv bands ntawm ib tug SatCR RF chaw nres nkoj rau 4 unicable satellite receivers.

SMATV (Satellite Master Antenna TV) yog qhov nrov tshaj plaws los muab satellite TV thiab terrestrial TV rau cov neeg nyob hauv cov tsev lossis cov zej zog. Ib txwm SMATV tuaj yeem faib cov ntsiab lus ntawm tus kav hlau txais xov los ntawm kev hloov mus rau satellite receivers hla coaxial cable. Vim tias qhov poob siab dua ntawm ntau dua satellite zaus, SMATV cable nrug tsawg dua 150 meter txawm tias IF online amplifier. Hom ob satellites SMATV system xav tau 9 RF cables los ntawm lub tsev ru tsev mus rau cascading multiswitchs, pab tsawg dua 100 cov neeg siv khoom hauv ib lub tsev. Rau ob lub satellites SMATV tshaj fiber ntau, Greatway Technology muaj GLB3500M-8 li FTTB tov thiab GLB3500E-4R li FTTH tov. FTTB kev daws teeb meem yuav tsum muaj satellite STB tsis tu ncua, thaum FTTH kev daws yuav tsum muaj satellite STB txhawb nqa tsis tau.

GLB3500E-4R muaj 1310nm / 1490nm / 1550nm WDM xaiv chaw nres nkoj rau kev ua haujlwm nrog GPON ONU hauv txhua daim ntawv thov FTTH, uas ua rau tag nrho satellite LNB cov ntsiab lus tau muab tso rau hauv GPON system.
