GFH1000-K FTTH CATV nnata nwere WDM ka ONU
Nkọwa ngwaahịa
GFH1000-K bụ 1550nm CATV eriri na ebe obibi ngwa anya nnata na 1310nm/1490nm WDM loop si ọdụ ụgbọ mmiri. Mgbe mgbasa ozi miri emi nke fiber gachara, mpaghara nnabata nke HFC CATV na-ebelata site na ndị debanyere aha 2000, gaa na ndị debanyere aha 500, ndị debanyere aha 125, ndị debanyere aha 50 na ugbu a otu ndị debanyere aha mgbe eriri n'ụlọ. Ebe ọ bụ na a na-ebufe ọrụ ịntanetị na GPON ma ọ bụ XGPON, GHF1000-K nwere 45MHz ruo 1000MHz ma ọ bụ 1218MHz zuru oke bandwidth RF maka ọrụ mgbasa ozi TV.
GFH1000-K nwere otu ọdụ ụgbọ mmiri ntinye anya, otu eriri wdm ọdụ ụgbọ mmiri, otu ntinye ike 12V DC na otu mmepụta RF. Dị ka ngwaọrụ ezinụlọ ONU, GFH1000-K nwere ụlọ plastik na-egbochi ọkụ yana ụlọ mpempe akwụkwọ dị n'ime iji hụ na ikewapụ na arụmọrụ RF dị.
Site na imewe AGC arụnyere n'ime ya, GFH1000-K bụ ngwa nkwụnye na ngwa egwu etinyere n'ụlọ ma ọ bụ ngwa SOHO. Ọ nwere fotodiode linearity dị elu na obere mkpọtụ GaAs amplifier, na-ewepụta RF dị elu maka ma ọ bụ TV analog ma ọ bụ dijitalụ QAM TV maka otu TV ma ọ bụ karịa n'otu ezinụlọ. Ike ntinye ngwa anya 1550nm nwere ike ịdị obere ka -15dBm mgbe akara RF bụ DVB-C QAM ma ọ bụ -8dBm mgbe akara RF bụ TV analọg. Ọdụ ụgbọ mmiri RF nwere nchebe ọnya yana ọkwa mmepụta RF nwere ike gbanwee ma ọ bụrụ na agbanyere nhọrọ MGC.
Ihe ntinye 1550nm mgbaàmà bandwit nwere ike ịbụ 1525nm ~ 1565nm wideband ngwa anya mgbaàmà na warara band 1550nm ~ 1560nm ngwa anya mgbaàmà. WDM nwere ike ịkwado 1310nm/1490nm GPON ma ọ bụ 1270nm/1577nm XGPON ma ọ bụ NGPON2. GFH1000-K nwere ike mee ka Greatway ONU ma ọ bụ ONU ndị ọzọ nwere ọrụ RF maka ịgbasa ọwa RF.
Atụmatụ ndị ọzọ:
• Kọmpat ụlọ na-egbochi ire ọkụ rọba.
• High Linearity Photodiode maka CATV RF.
• 45 ~ 1000MHz (n'okpuru ala) RF mmepụta (45 ~ 1218MHz nhọrọ).
• Ngwa anya AGC nso: -10dBm ~ 0dBm.
• Nhọrọ MGC: 0 ~ 15dB.
• 1310nm/1490nm Optical Bypass Port to ONU.
• Enwere ike ịkwalite WDM ka ọ tinye 1270nm/1577nm n'ọdụ ụgbọ mmiri maka XGPON ONU.
• Ike DC na ihe ngosi ihe ntinye anya LED.
• 12V DC nkwụnye ọkụ.
