I roto i nga tau kua pahure ake nei, ko ta maatau pakihi i kaha ki te tango me te keri i nga hangarau matatau i te kainga me nga whenua o waho. I tenei wa, he roopu tohunga to taatau kamupene e whakapau kaha ana ki to ahunga whakamuaWhakawhiti Poe Gigabit katoa,10/100/1000bit/S,32 Tauranga Itarangi Whakawhiti, Ka tino mihi matou ki nga hoa mai i nga wa katoa o te ao ki te mahi tahi ki a matou i runga i nga painga mo te wa roa.

He pai te kounga E1 Over Fiber - 4E1 PDH Fiber Multiplexer JHA-CPE4 (19 Inch 1U Momo) – JHA Taipitopito:

4E1 PDH Fiber Multiplexer JHA-CPE4

(19 Inihi 1U Momo)

Tirohanga

Ka whakaratohia e tenei taputapu te 1-4* E1 atanga, Paerewa 2 waea waea hei raupapa miihini-waea (he whiriwhiri). He tino ngawari. He mahi whakaoho. Ko te mahi he pono, he pumau, he iti te kaha o te kaha, te whakauru nui, te rahi iti.

Whakaahua Hua

Ngā āhuatanga

I runga i te mana-whaiaro IC
He matakite hihiko whanui modular
Ka whakamahi waea waea 2 paerewa (kaore i te kakau waea) kua tautuhia hei raupapa waea-waea-waea (he whiriwhiri)
E ū ana te atanga E1 ki te G.703, ka tango i te whakaora karaka mamati me te hangarau raka-waa maeneene
Ka ngaro te tohu whatu, ka kitea kua mutu te hiko o te taputapu mamao, kua momotuhia ranei te muka, me te tohu whakaoho ma te LED.
Ka taea e te taputapu rohe te tiro i te ahuatanga o te mahi a te taputapu mamao
Homai whakahau te atanga mamao Loop Back, ngawari te tiaki raina
Ko te tawhiti o te tuku ka eke ki te 2-120Km me te kore e aukati
AC 220V, DC-48V, DC+24V ka taea te whiriwhiri
DC-48V/DC+24V toha hiko me te mahi rapu polarity aunoa, ka whakauruhia kaore he wehewehenga i waenga i te pai me te kino.
