GFH1000-K FTTH CATV yakira hamwe na WDM kugeza ONU
Ibisobanuro ku bicuruzwa
GFH1000-K ni 1550nm ya CATV fibre kumurugo optique yakira hamwe na 1310nm / 1490nm WDM izenguruka 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 imikorere ya interineti yimuriwe muri GPON cyangwa XGPON, GHF1000-K ifite 45MHz kugeza kuri 1000MHz cyangwa 1218MHz yuzuye ya RF kuri serivisi yo gutangaza TV.
GFH1000-K ifite icyambu kimwe cyiza cyo kwinjiza, icyambu kimwe cya fibre wdm, icyuma kimwe cya 12V DC cyinjiza hamwe na RF isohoka. Kimwe nibikoresho byumuryango wa ONU, GFH1000-K ifite urumuri rudindiza amazu ya pulasitike hamwe namabati yimbere kugirango ibyuma bya RF byigunge kandi bikore.
Hamwe nimyubakire ya AGC, GFH1000-K nigikoresho cyo gukinisha no gukina byoroshye gushyirwaho murugo cyangwa porogaramu ya SOHO. Ifite umurongo mwinshi wa fotodiode hamwe n urusaku ruke GaAs amplifier, isohora RF nziza cyane kuri TV igereranya cyangwa TV QAM TV kuri televiziyo imwe cyangwa nyinshi mumuryango umwe. Imbaraga zo kwinjiza 1550nm zishobora kuba nkeya nka -15dBm mugihe ikimenyetso cya RF ari DVB-C QAM cyangwa -8dBm mugihe ikimenyetso cya RF ari TV igereranya. Icyambu cya RF gifite uburinzi bwihuse kandi urwego rusohoka rwa RF rushobora guhinduka niba MGC ihitamo.
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-K irashobora gutuma Greatway ONU cyangwa undi muntu wa gatatu ONU ufite imikorere ya RF yo gutangaza imiyoboro ya RF.
Ibindi biranga:
• Gucana umuriro wa plastike idindiza amazu.
• Photodiode Yumurongo muremure kuri CATV RF.
• 45 ~ 1000MHz (kumanuka) Ibisohoka bya RF (45 ~ 1218MHz birashoboka).
• Urwego rwiza rwa AGC: -10dBm ~ 0dBm.
• Urutonde rwa MGC rutemewe: 0 ~ 15dB.
• 1310nm / 1490nm Icyambu cyiza cya Bypass kuri ONU.
• WDM irashobora kuzamurwa kugirango ishyiremo icyambu cya 1270nm / 1577nm kuri XGPON ONU.
• DC Imbaraga hamwe na optique yinjiza LED.
• 12V DC adaptateur.
