2019 Te kounga teitei Tärua Impedance Pdh Mux - 4E1+4FE PDH Fiber Multiplexer JHA-CPE4F4 – JHA

4E1+4FE PDH Fiber Multiplexer JHA-CPE4F4

Tirohanga

Ko tenei taputapu e whakarato ana i te atanga 1-4 * E1, 1-4 * 10M / 100M atanga Ethernet (Waea Tere 100M) me te 2 atanga roha. 4* Ko te atanga Itarangi he atanga whakawhiti, ka taea te tautoko i te VLAN. 2 atanga roha ka taea te whakamahi hei teihana tuku o RS232/RS485/RS422 raraunga tukutahi. 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
• Itarangi (Te Raina Tere 100M) reeti atanga he 10M/100M, he haurua/taarua-katoa-Aunoa Nego
• E ū ana te atanga E1 ki te G.703, ka tango i te whakaora karaka mamati me te hangarau raka-waa maeneene
• Ka whakamahi waea waea 2 paerewa (kaore i te kakau waea) kua tautuhia hei raupapa waea-waea-waea (he whiriwhiri)
• Whakarato 2 atanga roha ka taea te whakamahi hei teihana whakawhiti o RS232/RS485/RS422 raraunga tukutahi.
• Ka ngaro te tohu whatu, ka kitea ka mutu te hiko o te taputapu mamao, ka momotuhia ranei te muka, ka tohu te 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, DC24V ka taea te whiriwhiri
• DC-48V/DC24V te mana whakawhiwhi mana te mahi kitenga polarity, Polarity-Free
