GFH1000-KP powerless CATV receiver rau ONU
Product Description
GFH1000-KP yog 1550nm powerless CATV fiber ntau rau lub tsev kho qhov muag receiver nrog 1310nm / 1490nm WDM voj tawm chaw nres nkoj.Tom qab kev sib sib zog nqus fiber ntau, HFC CATV optical receiver pab thaj chaw txo qis los ntawm 2000 cov neeg siv khoom, mus rau 500 tus neeg siv khoom, 125 tus neeg siv khoom, 50 tus neeg siv khoom thiab tam sim no ib tus neeg siv khoom siv fiber ntau hauv tsev.Txij li thaum lub zog hluav taws xob ntau dua tau siv dav hauv CATV tshaj tawm PON system, nws tuaj yeem siv lub zog tsis muaj qhov muag pom kev ua haujlwm ntawm -6dBm ~ -1dBm kom txo FTTH davhlau ya nyob twg tus nqi thiab kev siv hluav taws xob.Lub caij no, txij li kev ua haujlwm hauv internet tau pauv mus rau GPON lossis XGPON, GHF1000-KP muaj 45MHz mus rau 1000MHz lossis 1218MHz tag nrho RF bandwidth rau TV tshaj tawm kev pabcuam.
GFH1000-KP muaj ib qhov chaw nres nkoj optical input, ib fiber ntau wdm chaw nres nkoj thiab ib qho RF tso zis.Zoo li ONU tsev neeg cov khoom siv, GFH1000-KP muaj cov nplaim hluav taws kub hnyiab yas vaj tse.Cov khoom siv ntsaws thiab ua si no tau yooj yim ntsia hauv tsev lossis SOHO (chaw ua haujlwm me thiab chaw ua haujlwm hauv tsev) daim ntawv thov.Nrog high linearity photodiode thiab kho kom zoo passive RF txuam Circuit Court, GFH1000-KP tseem outputs tau zoo RF rau xws li analog TV los yog QAM TV rau ib los yog ntau tshaj TV teeb nyob rau hauv ib tsev neeg.Tsis zoo li GFH1000 FTTH CATV receiver nrog built-in GaAs amplifier, GFH1000-KP powerless FTTH CATV receiver cia siab rau lub optical input zog rau EDFA, lub 1550nm optical input zog yuav pom zoo kom tsawg li -6dBm thaum lub RF teeb liab DVB-C QAM los yog -1dBm thaum lub teeb liab RF yog analog TV.
Cov tswv yim 1550nm teeb liab bandwidth tuaj yeem yog 1525nm ~ 1565nm wideband optical teeb liab thiab nqaim band 1550nm ~ 1560nm optical teeb liab.
WDM tuaj yeem txhawb nqa 1310nm / 1490nm GPON lossis 1270nm / 1577nm XGPON lossis NGPON2.GFH1000-KP ua rau txhua tus neeg thib peb GPON ONU nrog RF muaj nuj nqi rau kev tshaj tawm RF channel.
Lwm yam nta:
• Compact yas nplaim retarding vaj tse.
• High Linearity Photodiode rau CATV RF.
• 45 ~ 1000MHz (downstream) RF tso zis.
• Tsis muaj DC fais fab Passive kev lag luam tsim.
• 1310nm / 1490nm Optical Bypass Chaw nres nkoj rau ONU.
• WDM tuaj yeem hloov kho kom suav nrog 1270nm / 1577nm reflection chaw nres nkoj rau XGPON ONU.
