4E1 PDH Fiber Multiplexer(Papamahi)
Ngā āhuatanga
*I runga i te IC mana-whaiaro
*Modular wide dynamic detector optical
*Ka whakamahia te waea waea 2 paerewa (kaore i te kakau waea) kua whakaritea 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
*I te ngaro o 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 a-rohe te tiro i te ahuatanga mahi a te taputapu mamao
*Homai he whakahau te atanga mamao Loop Back, ngawari te tiaki raina
*Ko te tawhiti o te whakawhiti 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 te tuku hiko me te mahi rapu polarity aunoa, ka whakauruhia kaore he wehewehenga i waenga i te pai me te kino.
