GLB3500E-2T Terr TV thiab Wideband LNB Optical Transmitter
Product Description
GLB3500E-2T fiber ntau optic transmitter yog tsim los xa cov ntaub ntawv siab transponder (xws li Hot Bird 13E) fiber ntau rau hauv tsev nrog lossis tsis muaj kev pabcuam GPON Ethernet. Ua hauj lwm nrog wideband LNB xws li Greatway GWB104G, GLB3500E-2T optical transmitter converts satellite wideband Kab rov tav 300MHz ~ 2350MHz, wideband Vertical 300MHz ~ 2350MHz RF los ntawm ib tug ntxaib LNB (tag nrho cov ntsiab lus ntawm ib txwm Quattro LNB fiber ntau TV) mus rau hauv ib tug terrestrial outputs thaum thim rov qab lub zog ntxaib LNB nrog 14V DC.
Direct Broadcasting Satellite (DBS) thiab Direct to Home (DTH) yog txoj kev nyiam tshaj plaws rau kev txaus siab rau satellite TV thoob ntiaj teb. Satellite kav hlau txais xov, coaxial cable, splitter los yog multi-switcher thiab satellite receiver yog tsim nyog. Txawm li cas los xij, kev teeb tsa satellite kav hlau txais xov yuav nyuaj rau cov neeg siv khoom nyob hauv cov tsev. SMATV (satellite mater kav hlau txais xov TV) yog ib qho kev daws teeb meem zoo rau cov neeg nyob hauv lub tsev lossis cov zej zog sib koom ib lub phaj satellite thiab cov kav hlau txais xov hauv av. Nrog fiber ntau cable, SMATV RF teeb liab tuaj yeem xa mus rau 30Km nyob deb lossis faib rau 32 chav ncaj qha, mus rau 320 lossis 3200 lossis 32000 chav tsev ntawm GWA3530 fiber optic amplifier.
GLB3500E-2T optical transmitter muaj +6dBm optical tso zis, +17dBm tso zis los yog +20dBm tso zis, txhawb 1x32 los yog 1x128 los yog 1x256 fiber ntau rau lub tsev kho qhov muag receiver (FTTH LNB) ncaj qha.
