I-GLB3500M-4D IiSathelayithi ezine DWDM FTTH eneGPON
Ingcaciso yeMveliso
I-GLB3500M-4D yimodyuli ye-DWDM Broadband RF ifayibha ikhonkco, ithumela ezine 950~2150MHz Satellite RF kunye ne-174~806MHz yeTerestrial TV RF ngaphezulu kwefayibha enye ye-SM ukuya kubabhalisi be-FTTH abaninzi.IiRF ezine zesathelayithi zinokuba yi-VL/VH/HL/HH ukusuka kwi-Quattro LNB enye okanye ezine ezimile i-32UB ukusuka kwii-dCSS LNB ezine zesathelayithi.
Iisathelayithi ezine zinezitshixo ezininzi kwisathelayithi nganye.Ngapha koko, kuphela i-20% imixholo yesathelayithi edumileyo kubabhalisi abangama-80%.Zonke iziqulatho ezisuka kwiisathelayithi ezine ngaphezulu kwentambo yecoaxial ukuya kwintambo yosinga kwikhaya ngalinye zibiza kakhulu.Inkqubo ye-GLB3500M-4D ikhetha i-transponders ethandwa kakhulu kubo bonke ababhalisi.Iitransponder ezingama-32 kwisathelayithi nganye kufuneka zibandakanye eyona mixholo ibonakalisiweyo yesathelayithi.Ngeteknoloji ye-4ch ye-DWDM kunye namandla aphezulu e-1550nm amplifier optical, i-GLB3500-4D inokufaka ii-satellites ze-4 kunye ne-transponders ye-128 epheleleyo kuyo nayiphi na inkqubo ye-GPON okanye i-XGPON.Kwimowudi emileyo ye-dCSS LNB, abamkeli besathelayithi banokuba yimowudi eqhelekileyo yokubukela yonke imixholo emi-4 ekhethiweyo yesathelayithi.
I-GLB3500M-4D i-fiber link iquka i-GLB3500M-4TD DWDM i-optical transmitter kunye ne-GLB3500M-4RD4 FTTH i-optical receiver.I-optical receiver ine-4 izibuko ze-RF, izibuko ngalinye lixhasa ukubukela i-32UB engenayo nayiphi na i-satellite engenayo.Ngee-DWDM lasers/photodiode kunye nengxolo ephantsi ye-RF yokulawula ukufumana isekethe, enye i-GLB3500M-4TD inokuhambisa umgangatho ophezulu weRF ukuya kubuninzi be-32 GLB3500M-4RD4 abamkeli be-optic ngokuthe ngqo okanye amawaka e-GLB3500M-4RD4 abamkeli be-optic ngokusebenzisa i-amplifier yamandla aphezulu.
Ezinye iimpawu:
• Ulwakhiwo lwezindlu zealuminiyam eneheatsink egqwesileyo kunye ne-RF yodwa.
• I-Quattro LNB enye (okanye ezine dCSS LNBs) kunye neTerr TV ngosasazo olunye lwe-SM fiber.
• I-bandwidth ye-RF yesathelayithi ezine: 950MHz ukuya ku-2150MHz.
• Ukubuyisela umva i-13V/18V DC ukuya kwiQuattro LNB okanye i-dCSS LNB.
• Ububanzi be-TV yeTerestrial: 174~806MHz.
• I-1550nm C-band DWDM wavelengths kuluhlu lwe-EDFA okanye i-EYDFA.
• I-AGC kwisidlulisi samehlo kunye nomamkeli.
• High Linearity Photodiode.
• Ukwahlulwa kweRF okugqwesileyo.
• Ingxolo ephantsi ye-RF Gain Control circuit.
• 19” 1RU House Optional.
