GWR1200 CATV Node nziza
Ibisobanuro ku bicuruzwa
GWR1200 Optical Node ifite inzu yo hanze ya aluminiyumu isohora inzira igana inzira igereranya TV, ibimenyetso bya DVB-C na CMTS DS no kohereza ibimenyetso bya kabili modem byerekana uburyo busanzwe cyangwa buturika hejuru ya fibre imwe ya Bi-icyerekezo cyangwa fibre ya 2. Nibyiza kuri fibre igezweho kubibanza (FTTP) na fibre yinyubako (FTTB) kuri CATV numuyoboro wa interineti. GWR1200 node itanga umusaruro mwinshi wa RF kugeza kuri 1,2 GHz (1218MHz) izagabanya cyangwa ikureho ibikenerwa byongera imbaraga nyuma yumurongo.
GWR1200 node nibyiza kubisabwa byinshi: MDU, kaminuza, ibitaro na parike yubucuruzi. GWR1200 ifite 50dBmV isohoka ikora urwego urwo arirwo rwose. Garuka inzira yohereza irashobora kuba 1310nm cyangwa 1550nm bitewe na sisitemu isabwa. Ubuhanga bwa WDM butemewe butuma ibikorwa byuburyo bubiri kuri fibre imwe. Imiyoboro ya CWDM itangwa kugirango ihuze inzira nyinshi zuburyo bubiri kuri fibre imwe.
Nka optique yo hanze, GWR1200 yateguye uburyo bwa 4KV bwo kurinda ibyambu byose bya RF.
GWR1200 yo gusubiza inzira yoherejwe irashobora gushyirwaho muburyo buturika kugirango ugabanye urusaku rwinzira. Igikoresho gikoresha fibre imwe kandi yakira ibimenyetso byamanuka kuri 1550nm hanyuma ibyuma bisubiza birashobora gutumizwa nka 1310nm cyangwa 1610nm cyangwa CWDM yumuraba bitewe nibisabwa na sisitemu. Nkigikoresho cya RFOG kirahujwe na DOCSIS® hamwe numurage wose HFC inyuma yibiro byakazi.
Ibindi biranga:
• Aluminium Gupfa Amazu yo hanze.
• Fibre ebyiri cyangwa fibre imwe bi-icyerekezo cya optique yohereza.
• 1005MHz cyangwa 1218MHz inzira yimbere inzira ya RF.
• Ingaragu 110dBµV cyangwa ebyiri 106 dBµV Imbere ya RF ibisubizo.
• Imbere Inzira 15dB Ahantu hahanamye na 15dB attenuator.
• AGC ikora neza -5dBm ~ + 1dBm optique yinjiza.
• 5 ~ 85MHz / 204MHz gusubiza umurongo wa RF umurongo.
• Kugera kuri 16 CWDM DFB laser yumurambararo ukora muburyo buturika.
• 4KV Kurinda.
• 60V cyangwa 220V itanga amashanyarazi.
