GFH1000-K FTTH CATV receiver nrog WDM rau ONU
Product Description
GFH1000-K yog 1550nm 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 kev ua haujlwm hauv is taws nem hloov mus rau GPON lossis XGPON, GHF1000-K muaj 45MHz txog 1000MHz lossis 1218MHz tag nrho RF bandwidth rau TV tshaj tawm kev pabcuam.
GFH1000-K muaj ib qhov chaw nres nkoj optical input, ib qho fiber ntau wdm chaw nres nkoj, ib qho 12V DC lub zog tawm tswv yim thiab ib qho RF tso zis. Zoo li ONU tsev neeg cov khoom siv, GFH1000-K muaj cov nplaim hluav taws kub nyhiab cov vaj tsev nrog cov ntawv hlau sab hauv kom ntseeg tau tias kev sib cais RF thiab kev ua haujlwm.
Nrog tsim-hauv AGC tsim, GFH1000-K yog lub ntsaws thiab ua si ntaus ntawv yooj yim ntsia hauv tsev lossis SOHO daim ntawv thov. Nws muaj high linearity photodiode thiab suab nrov GaAs amplifier, outputs zoo RF rau xws li analog TV lossis digital QAM TV rau ib lossis ntau lub TV hauv ib tsev neeg. Lub 1550nm optical input fais fab tuaj yeem qis li -15dBm thaum lub teeb liab RF yog DVB-C QAM lossis -8dBm thaum lub teeb liab RF yog analog TV. RF chaw nres nkoj muaj kev tiv thaiv surge thiab RF tso zis theem tuaj yeem kho tau yog tias qhov kev xaiv MGC tau qhib.
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-K tuaj yeem ua rau Greatway ONU lossis lwm tus neeg sab nrauv ONU nrog RF muaj nuj nqi rau kev tshaj tawm RF channel.
