GLB3500M-3 Terr TV da LNB mai fadi guda ɗaya akan fiber
Bayanin Samfura
GLB3500M-3 shine hanyar haɗin yanar gizo na CWDM mai sauƙi na RF, yana watsa 290MHz ~ 2350MHz Satellite RF (mai goyan bayan UK 290MHz ~ 2340MHz ko Turai 300MHz ~ 2350MHz) da ɗaya 45MHz ~ 806MHz Terrestrial TV RF masu biyan kuɗi fiye da SM guda ɗaya. Faɗin RF yana kan 1530nm ko 1550nm, RF TV na ƙasa yana kan 1570nm. Akwai fiber optic CWDM mux ko na'urar demux akan na'urar watsawa ta gani ko karɓa don gane watsa fiber guda ɗaya.
SMTV (Satellite Master Antenna TV) sananne ne don bayar da talabijin ta tauraron dan adam da TV ta ƙasa ga masu biyan kuɗi da ke zaune a cikin gidaje ko al'umma. SMTV na al'ada na iya rarraba abun ciki na eriya ta hanyar multiswitch zuwa masu karɓar tauraron dan adam akan kebul na coaxial. Saboda babban hasara a mafi girman mitar tauraron dan adam, nisan kebul na SMTV bai wuce mita 150 ba ko da tare da IF akan layi. Ba kamar tsarin Quattro LNB SMTV na yau da kullun ba, tsarin LNB SMTV mai faɗi yana da rabin masu haɗin RF da rabin lambobin kebul, wanda ke adana farashin watsawa. Bayan fiber zuwa ginin, wideband SMTV Optical receiver dole ne yayi aiki tare da dCSS multiswitch don samun fitowar RF guda ɗaya tare da ɗigon mai amfani 32, inda kowane mai amfani ga mai amfani da tauraron dan adam STB mai amfani. Wannan fiber guda ɗaya zuwa ginin da kuma kebul na coaxial guda ɗaya ga masu amfani da yawa a cikin ginin yana sanya shigarwar kebul ɗin da kulawa cikin sauƙi.
GLB3500M-3 fiber mahada ya hada da GLB3500M-3T watsawa na gani da kuma GLB3500M-3R na gani mai karɓar. Tare da CWDM lasers/photodiode da ƙananan amo RF samun ikon sarrafawa, GLB3500M-3T ɗaya na iya sadar da RF mai inganci zuwa matsakaicin 32pcs GLB3500M-3R masu karɓar gani kai tsaye.
Wasu Fasaloli:
• Ƙaramin gidaje na aluminum.
• 3 mai zaman kansa mai zaman kansa RF akan watsa fiber SM guda ɗaya.
• Kowane bandwidth na RF: wideband LNB 290 ~ 2350MHz ko 45 ~ 806MHz.
• High Linearity Photodiode.
• Ƙaramar amo RF Gain Control kewaye.
