GLB3500MT Terr TV da Sat Fiber Optic Transmitter
Bayanin Samfura
GLB3500M shine 45 ~ 2600MHz RF na zamani akan hanyar haɗin fiber, watsa tashoshin TV na Terrestrial da L-Band RF guda ɗaya akan fiber ɗaya.
Tauraron Dan Adam na Watsa Labarai Kai tsaye (DBS) da Kai tsaye zuwa Gida (DTH) sune mafi mashahuri hanyar jin daɗin tauraron dan adam TV a duk duniya. Don yin shi, eriya ta tauraron dan adam, kebul na coaxial, splitter ko multi-switcher da tauraron dan adam mai karɓa suna da mahimmanci. Koyaya, shigar da eriya ta tauraron dan adam na iya zama da wahala ga masu biyan kuɗi da ke zaune a cikin gidaje. SMTV (tauraron tauraron dan adam TV eriya) mafita ce mai kyau ga mutanen da ke zaune a cikin ginin ko al'umma don raba tasa tauraron dan adam daya da eriyar TV ta duniya. Tare da kebul na fiber, ana iya isar da siginar SMTV RF zuwa 30Km mai nisa ko rarraba zuwa gidaje 32 kai tsaye, zuwa gidaje 320 ko 3200 ko 32000 ta hanyar GWA3530 fiber optic amplifier.
GLB3500M ya ƙunshi GLB3500MT na'urar watsawa da GLB3500MR mai karɓa. GLB3500MT mai watsawa yana da tashar shigar da RF ɗaya ko biyu yayin da GLB3500MR yana da tashar fitarwa ta RF ɗaya. Tare da high linearity 1550nm uncooled DFB Laser, photodiode da kuma low amo RF sami iko kewaye, GLB3500MT iya isar da high quality Terrestrial TV tashoshi da tauraron dan adam RF a kan fiber zuwa 'yan biyan kuɗi kai tsaye ko dubban FTTH masu biyan kuɗi ta EDFA. Tare da 1310nm/1490nm/1550nm WDM zaɓi, GLB3500M na iya saka L-Band+TV RF akan GPON/GEPON. Bayan sigar modular, GLB3500M na iya samun nau'in 19”1RU akan buƙata. Fiber zuwa nau'in gidaje na filastik na GLB3500MR shine GFH2000 na gani LNB, inda mai biyan kuɗi na FTTH kawai yana buƙatar fiber ɗaya a ciki kuma yana fitar da siginar tauraron dan adam zuwa ɗakuna da yawa a cikin dangi.
