GWR1000M CATV MiniNode
Ibisobanuro ku bicuruzwa
GWR1000M Optical MiniNode ifite icyambu kimwe cya RF gifite inzira igana imbere ya TV, ibimenyetso bya DVB-C na CMTS DS hamwe nibimenyetso bya kabili modem byerekana uburyo busanzwe cyangwa buturika hejuru ya fibre imwe ya Bi-icyerekezo cyangwa fibre ebyiri.Hamwe n'amazu ya aluminiyumu apfuye, GWR1000M nibyiza kuri fibre igezweho kubibanza (FTTP), fibre hasi (FTTF) cyangwa fibre yinyubako (FTTB) ikoreshwa kuri CATV numuyoboro wa interineti.GWR1000M node itanga umusaruro umwe wa RF kugeza kuri 1,2 GHz (1218MHz) ifasha tereviziyo nkeya cyangwa igatwara MDU amplifier mumashanyarazi ya coaxial.
GWR1000M node nibyiza kubisabwa byinshi: MDU, kaminuza, ibitaro na parike yubucuruzi.Hamwe na 20dBmV RF isohoka muburyo bwa AGC, mininode ya GWR1000M ikora ingano ntoya byoroshye.Garuka inzira yohereza irashobora kuba 1310nm cyangwa 1550nm kuri 2ndicyambu cya fibre, bitewe na sisitemu isabwa.Ubuhanga bwa WDM butemewe butuma ibikorwa byuburyo bubiri kuri fibre imwe.CWDM igaruka inzira optique yumurambararo irahari kugirango uhuze inzira ebyiri-zibiri kuri fibre imwe.
Nka optique yo mu nzu, GWR1000M irashobora gushirwa kurukuta ukoresheje imigozi cyangwa kumeza.Yashizeho uburyo bwo kurinda 6KV kurinda ibyambu byose bya RF.
GWR1000M ifite icyambu kimwe -20dB, ikurikirana byoroshye inzira igana imbere kandi igaruka inzira ya RF.
GWR1000M irashobora gukoreshwa ku cyambu cyigenga cya RF hamwe na adapt ya kure ya 15V DC, ituma ingufu za DC zigabanuka munsi ya metero 30 z'uburebure bwa RG6.GWR1000M irashobora kandi gukoreshwa ku cyambu gisohoka RF.
Ibiranga
• Amazu yuzuye ya Aluminium
• 1002 / 1218MHz inzira igana imbere umurongo wa RF
• 20dBmV RF isohoka muri AGC
