GFH1000-KP engenamandla CATV umamkeli for ONU
Ingcaciso yeMveliso
I-GFH1000-KP yi-1550nm ifayibha yeCATV engenamandla kwisamkeli sasekhaya esine-1310nm/1490nm WDM loop ngaphandle kwezibuko. 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. Ekubeni iamplifier yamandla aphezulu aphezulu isetyenziswa ngokubanzi kwinkqubo ye-PON yosasazo yeCATV, kunokwenzeka ukuba kusetyenziswe isamkeli esingenamandla esisebenza kwi -6dBm~-1dBm ukunciphisa iindleko ze-FTTH ze-terminal kunye nokusetyenziswa kwamandla. Ngeli xesha, ekubeni umsebenzi we-intanethi ukhutshelwa kwi-GPON okanye i-XGPON, i-GHF1000-KP ine-45MHz ukuya kwi-1000MHz okanye i-1218MHz epheleleyo ye-RF bandwidth yenkonzo yosasazo lwe-TV.
I-GFH1000-KP inezibuko elinye le-optical input, enye i-fiber wdm port kunye ne-RF enye ephumayo. Njengezixhobo zosapho lwe-ONU, i-GFH1000-KP inedangatye elibuyisela umva kwizindlu zeplastiki. Le plagi kunye nesixhobo sokudlala sifakwe ngokulula ekhaya okanye kwi-SOHO (iofisi encinci kunye neofisi yasekhaya) isicelo. Ngephotodiode yomgca ophezulu kunye nesekethe ehambelanayo yeRF elungelelaniswe kakuhle, i-GFH1000-KP isavelisa umgangatho owamkelekileyo weRF nokuba yi-analog yeTV okanye yedijithali ye-QAM TV yeseti enye okanye ngaphezulu kusapho olunye. Ngokungafaniyo ne-GFH1000 FTTH CATV umamkeli nge-GaAs amplifier eyakhelwe-ngaphakathi, i-GFH1000-KP engenamandla FTTH CATV umamkeli uxhomekeke kumandla okufakwayo optical e-EDFA, i-1550nm amandla okufakwayo optical angacetyiswa asezantsi njenge -6dBm xa isignali yeRF i-DVB-CAM QAM okanye -1dBm xa isignali yeRF iyi-analog TV.
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-KP yenza ukuba naliphi na iqela lesithathu iGPON ONU nomsebenzi weRF wokusasaza amajelo eRF.
Ezinye iimpawu:
• Ulwakhiwo lweplastiki olubambekayo olulibazisa amadangatya.
• I-High Linearity Photodiode ye-CATV RF.
• 45 ~ 1000MHz (ezantsi) Imveliso yeRF.
• Akukho mbane we-DC uyilo loqoqosho lwePassive.
• I-1310nm/1490nm i-Optical Bypass Port ukuya kwi-ONU.
• I-WDM inokuphuculwa ukuze ibandakanye i-1270nm/1577nm izibuko ebonisa i-XGPON ONU.
