GFH1000-KP idafite ingufu za CATV yakira kuri ONU
Ibisobanuro ku bicuruzwa
GFH1000-KP ni 1550nm idafite ingufu za CATV fibre kugeza murugo optique yakira hamwe na 1310nm / 1490nm WDM ikuramo icyambu.Nyuma yubukangurambaga bwimbitse, HFC CATV yakira optique yakira ahantu igabanuka kuva kubakoresha 2000, kugeza kubiyandikishije 500, abafatabuguzi 125, abafatabuguzi 50 none abafatabuguzi umwe iyo fibre murugo.Kubera ko ingufu za optique amplifier zikoreshwa cyane muri CATV isakaza PON sisitemu, birashoboka gukoresha imashini itagira amashanyarazi ikora kuri -6dBm ~ -1dBm kugirango igabanye igiciro cya FTTH no gukoresha amashanyarazi.Hagati aho, kubera ko imikorere ya interineti yimuriwe muri GPON cyangwa XGPON, GHF1000-KP ifite 45MHz kugeza kuri 1000MHz cyangwa 1218MHz yuzuye ya radiyo yuzuye ya serivisi yo gutangaza TV.
GFH1000-KP ifite icyambu kimwe cyo kwinjiza optique, icyambu kimwe cya fibre wdm hamwe nibisohoka RF.Kimwe nibikoresho byumuryango ONU, GFH1000-KP ifite flame idindiza amazu ya plastike.Gucomeka no gukina ibikoresho byashizwe byoroshye murugo cyangwa SOHO (biro nto n'ibiro byo murugo).Hamwe na fotodi yumurongo muremure kandi uhinduwe neza na RF ihuza umuzenguruko, GFH1000-KP iracyasohoka RF yemewe yemewe kuri TV igereranya cyangwa TV ya QAM TV kuri televiziyo imwe cyangwa nyinshi mumuryango umwe.Bitandukanye na GFH1000 FTTH CATV yakira hamwe yubatswe muri GaAs amplifier, GFH1000-KP idafite ingufu za FTTH CATV yakira imbaraga zo kwinjiza optique ya EDFA, 1550nm optique yinjiza irashobora gusabwa munsi ya -6dBm mugihe ikimenyetso cya RF ari DVB-C QAM cyangwa -1dBm mugihe ibimenyetso bya RF ari TV igereranya.
Iyinjiza 1550nm yerekana umurongo mugari irashobora kuba 1525nm ~ 1565nm mugari wa optique ya optique hamwe na bande ya 1550nm ~ 1560nm ya optique.
WDM irashobora gushyigikira bisanzwe 1310nm / 1490nm GPON cyangwa 1270nm / 1577nm XGPON cyangwa NGPON2.GFH1000-KP ituma igice cya gatatu GPON ONU gifite imikorere ya RF yo gutangaza imiyoboro ya RF.
Ibindi biranga:
• Gucana umuriro wa plastike idindiza amazu.
• Photodiode Yumurongo muremure kuri CATV RF.
• 45 ~ 1000MHz (hepfo) Ibisohoka RF.
• Nta mbaraga za DC Igishushanyo mbonera cyubukungu.
• 1310nm / 1490nm Icyambu cyiza cya Bypass kuri ONU.
• WDM irashobora kuzamurwa kugirango ishyiremo icyambu cya 1270nm / 1577nm kuri XGPON ONU.
