I-GLB3500M-4D Amasathelayithi Amane i-DWDM FTTH ene-GPON
Incazelo Yomkhiqizo
I-GLB3500M-4D iyisixhumanisi se-modular DWDM Broadband RF fibre, sidlulisa ama-Satellite RF amane angu-950~2150MHz kanye ne-174~806MHz Terrestrial TV RF eyodwa ngefayibha eyodwa ye-SM kuya kwababhalisile be-FTTH abaningi. Ama-RF amasathelayithi amane angaba yi-VL/VH/HL/HH kusukela ku-Quattro LNB eyodwa noma ama-32UB amane amile kuma-dCSS LNB amane.
Amasathelayithi amane anama-transponder amaningi kusethelayithi ngayinye. Eqinisweni, okuqukethwe kwesathelayithi okungu-20% kuphela okudumile kwababhalisile abangama-80%. Konke okuqukethwe kusukela kumasathelayithi amane phezu kwekhebula elikhoaxial kuya kukhebula lefayibha ekhaya ngalinye kuyabiza. Uhlelo lwe-GLB3500M-4D lukhetha ama-transponder aziwa kakhulu kubo bonke ababhalisile. Ama-transponder angu-32 asuka ku-satellite ngayinye kufanele ahlanganise okuqukethwe okufakwe kakhulu kwesathelayithi. Ngobuchwepheshe be-4ch DWDM namandla aphezulu we-1550nm optical amplifier, i-GLB3500-4D ingafaka amasathelayithi angu-4 anengqikithi yama-transponder angu-128 kunoma iyiphi i-GPON noma i-XGPON uhlelo. Kumodi emile ye-dCSS LNB, abamukeli besathelayithi bangaba imodi evamile yokubuka konke okuqukethwe okukhethiwe kwesathelayithi oku-4.
Isixhumanisi se-GLB3500M-4D se-fiber sihlanganisa i-GLB3500M-4TD DWDM optical transmitter kanye ne-GLB3500M-4RD4 FTTH isamukeli esibonakalayo. Isamukeli esibonakalayo sinezimbobo ze-RF ezi-4, imbobo ngayinye isekela ukubuka okungu-32UB okungenayo kwanoma iyiphi isathelayithi engenayo. Ngama-laser/photodiode e-DWDM kanye nesekhethi yokulawula inzuzo ye-RF yomsindo ophansi, i-GLB3500M-4TD eyodwa ingaletha i-RF yekhwalithi ephezulu iye kufika ku-32 GLB3500M-4RD4 izamukeli optic ngokuqondile noma izinkulungwane zabamukeli be-optic ye-GLB3500M-4RD4 nge-amplifier yamandla aphezulu.
