GFH1000-K FTTH CATV umamkeli nge WDM ukuya ONU
Ingcaciso yeMveliso
I-GFH1000-K yi-1550nm i-CATV ifayibha ukuya kwi-home optical receiver ene-1310nm/1490nm i-WDM loop out port. Emva komkhankaso we-fiber deep, i-HFC CATV i-optical receiver indawo yokukhonza iyancipha ukusuka kubabhalisi be-2000, ukuya kubabhalisi be-500, ababhalisile be-125, ababhalisile be-50 kwaye ngoku ababhalisile omnye xa i-fiber ekhaya. Ukusukela ukuba umsebenzi we-intanethi ukhutshelwa kwi-GPON okanye i-XGPON, i-GHF1000-K ine-45MHz ukuya ku-1000MHz okanye i-1218MHz i-RF epheleleyo yenkonzo yosasazo lwe-TV.
I-GFH1000-K inezibuko elinye le-optical input, enye i-fiber wdm port, enye i-12V DC igalelo lamandla kunye ne-RF enye imveliso. Njengezixhobo zosapho ze-ONU, i-GFH1000-K inezindlu zeplastiki ezibuyisela idangatye kunye nezindlu zangaphakathi zentsimbi ukuqinisekisa ukwahlukaniswa kunye nokusebenza kweRF.
Ngoyilo olwakhelwe ngaphakathi lwe-AGC, i-GFH1000-K yiplagi kunye nesixhobo sokudlala esifakwe lula ekhaya okanye kwi-SOHO application. Ine-photodiode yomgca ophezulu kunye nesandisi sesandi esiphantsi se-GaAs, ikhupha umgangatho ophezulu we-RF nokuba yi-analog TV okanye i-digital QAM TV ye-TV enye okanye ngaphezulu kwintsapho enye. I-1550nm igalelo lamandla okukhanya anokuba ngaphantsi njenge -15dBm xa isignali yeRF iyi-DVB-C QAM okanye -8dBm xa isignali yeRF iyi-analog TV. Izibuko le-RF linokhuseleko lokunyuka kunye nenqanaba lemveliso yeRF linokuhlengahlengiswa ukuba ukhetho lwe-MGC luvuliwe.
Igalelo le-1550nm i-bandwidth yesignali ingaba yi-1525nm ~ 1565nm i-wideband optical signal kunye nebhendi emxinwa 1550nm ~ 1560nm isignali ye-optical. I-WDM inokuxhasa rhoqo i-1310nm / 1490nm GPON okanye i-1270nm / 1577nm XGPON okanye i-NGPON2. I-GFH1000-K inokwenza iGreatway ONU okanye naliphi na iqela lesithathu i-ONU enomsebenzi weRF wokusasaza amajelo eRF.
Ezinye iimpawu:
• Ulwakhiwo lweplastiki olubambekayo olulibazisa amadangatya.
• I-High Linearity Photodiode ye-CATV RF.
• 45~1000MHz (ezantsi komlambo) i-RF Output (45~1218MHz ngokuzithandela).
• Uluhlu lwe-AGC olubonakalayo: -10dBm ~ 0dBm.
• Uluhlu lwe-MGC olukhethwayo: 0 ~ 15dB.
• I-1310nm/1490nm i-Optical Bypass Port ukuya kwi-ONU.
• I-WDM inokuphuculwa ukuze ibandakanye i-1270nm/1577nm izibuko ebonisa i-XGPON ONU.
• Amandla e-DC kunye ne-optical input LED isalathisi.
• 12V DC iadaptha yamandla.
