Ngaio China Modular Multi-Ratonga Pdh - 8E1+4GE PDH Fiber Multiplexer JHA-CPE8G4 – JHA

8E1+4GE PDH Fiber Multiplexer JHA-CPE8G4

Tirohanga

Ko tenei taputapu te taputapu tuku mata-ki-ira i whakawhanakehia i runga i te VLSI. Ka whakaratohia e te taputapu te atanga 1-8 * E1, 1-4 * 10 / 100 / 1000M atanga Ethernet (Waea Tere 1000M) me te 2 atanga roha. 4* Ko te atanga Itarangi he atanga whakawhiti, ka taea te tautoko i te VLAN. Ka taea te whakamahi 1 atanga roha rite te hongere tuku o RS232 / RS485 / RS422 raraunga tukurite, tohu whakapā maroke, 1Channel waea pakihi mamati taea te kōwhiringa. 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
