GWR1000M CATV MiniNode
Whakaahuatanga Hua
Ko te GWR1000M Optical MiniNode he tauranga RF kotahi me te ara whakamua TV tairitenga, tohu DVB-C me CMTS DS me nga tohu pouwhanga taura taura whakarunga i te aratau pakaru noa ranei i runga i te muka Bi-directional kotahi, e rua ranei nga muka. Ki te whare mate konumohe o roto, he pai te GWR1000M mo te muka matatau ki te whare (FTTP), te muka ki te papa (FTTF) ranei te muka ki te whare (FTTB) tono i CATV me nga whatunga ipurangi. Ko te node GWR1000M e whakarato ana i tetahi putanga RF ki te 1.2 GHz (1218MHz) e tautoko tika ana i etahi kapeka pouaka whakaata, ka peia ranei te whakakaha MDU ki te whatunga taura coaxial.
He pai te node GWR1000M mo nga tono kiato teitei: MDU, whare wananga, hohipera me nga papa pakihi. Ki te 20dBmV RF putanga i te aratau AGC, GWR1000M mininode kakau iti whakaturanga watea. Ka taea e te kaiwhakawhiti ara hoki te 1310nm, te 1550nm ranei i runga i te 2ndtauranga muka, i runga i nga whakaritenga o te punaha. Ko te hangarau WDM kōwhiringa ka taea te mahi e rua-ara i runga i te muka kotahi. CWDM ara hokinga roangaru whatu e wātea ana ki te whakakotahi i te maha o nga pona-rua ki runga i te muka kotahi.
Hei pona whatu o roto, ka taea te whakanoho GWR1000M ki runga i te pakitara ma te wiri, ki runga tepu ranei. Kua hangaia e ia te whakamarumaru ngaru 6KV i nga tauranga RF katoa.
Ko te GWR1000M he tauranga whakamatautau -20dB, he ngawari te aro turuki i te huarahi whakamua me te hokinga mai o te tohu RF.
Ka taea te whakakaha i te GWR1000M i te tauranga RF motuhake me te urutau hiko 15V DC mamao, e taea ai te heke ngaohiko DC i te iti iho i te 30 mita te roa o te taura RG6. Ka taea hoki te whakakaha GWR1000M i te tauranga putanga RF.
