4E1+4FE(Wehenga-a-tinana)JHA-CPE4WF4

PDH Fiber Multiplexer

Tirohanga

Ko tenei raupapa o nga taputapu ko te kamupene i whakawhanakehia te tuku muka PDH i whakatapua i te VLSI i whakawhanakehia i runga i te waahi ki te tohu taputapu whakawhiti whatu. Whakarato 1-4 E1 atanga, tuatahi me te pūrua muka hononga atanga whatu, 1-4 wehe tinana 10/100M Tere atanga Itarangi (motuhake wha-waea tere 100M, tapeke hōkaiipurangi ko 4*100M), me te rua atanga roha pakihi. 2 Ka taea te whakamahi atanga ratonga roa hei RS232 / RS485 / RS422 raraunga tukutahi, he tino ngawari te tono. Kotahi te waea ratonga mamati, he tino ngawari te tono. Ma te mahi whakaoho tangi, te pumau katoa, te pono, te iti o te kaha o te kaha, te whakauru nui, te rahi iti.
