GWR3300 Quad Return Ara kaiwhiwhi
Whakaahuatanga Hua
GWR3300 whatanga Maunga ara hoki kaiwhiwhi kua hangaia mo te roto CATV hoki tohu whiwhi. I roto i te whatanga 19" 1RU, e 4 te nuinga o nga kaiwhakawhiwhi huarahi hokinga motuhake, e whiwhi ana i nga tohu tohu arai hoki mai i o tatou pona whatu i roto i te take o te muka ki te whare, e wha ranei te whatunga PON mena he muka ki te kainga. Kei ia kaikawe he hanga i roto i te reo iti haruru PIN diode, GaAs preamplifier, tātari paahi iti me te whakakaha RF taumata teitei, e whakarato ana ki te 45dBmV taumata whakaputa i te 19” 1RU paewhiri muri. Ka tautokohia e te diode PIN te roangaru whatu 1260nm~1650nm, tae atu ki te 1310nm rongonui, 1550nm me etahi atu waahana CWDM. I te papa o mua, he tauranga whakamatautau RF -20dB me tetahi attenuator ka taea te whakarite mo ia kaiwhiwhi, ka taea te whakarite ngawari o ia ara hokinga taumata putanga RF. Ko te hōkaiipurangi o ia kaiwhiwhi ara hokinga ko te 5MHz~204MHz, he rite ki te wehenga o te 42/54MHz, 65/85MHz, 85/102MHz, 204/258MHz, e tautoko ana i Docsis 2.0, Docsis 3.0 me Docsis 3.1 pouwhanga taura pouwhanga RF tohu. Arā, ka taea e GWR3300 te mahi ki nga tohu katoa o te CATV whakarunga, ahakoa nga pona whatu me nga micronodes RFoG.
I tua atu i nga putanga RF ara hoki motuhake e wha, kotahi ano te tauranga RF e whakakotahi ana i nga putanga kaiwhiwhi e wha hei putanga RF kotahi, he pai ki te hononga tauranga CMTS US.
Ma te kaha o te photodiode me te whakahiato ranu, ka tukuna e GWR3300 he roopu ara hokinga ma mo nga tohu rere-rere-rerenga Pouwhanga Waea. Ko te tohu hiko hiko me te tauranga whakamatautau RF kei te papa o mua ka tohu i te mana o te kaiwhiwhi.
Ētahi atu āhuatanga:
• 1550nm / 1310nm te roangaru rua.
• 4 RPR motuhake i roto i te kotahi 19" 1U whatanga paerewa.
• Haruru iti, photodiode ahorangi teitei.
• 5- 204 MHz RF Aratuku.
• E rua nga whiriwhiringa paahi roopu hei pehi i te haruru whakarunga.
• Te whakatikatika putanga me te whakamatautau -20dB RF e waatea ana i te papa o mua.
