8E1 + 4FE (Kev cais lub cev)JHA-CPE8WF4

PDH Fiber ntau ntau

Txheej txheem cej luam

Cov khoom siv no yog lub tuam txhab tsim PDH fiber ntau kis tau tus mob siab VLSI tsim los ntawm kev taw tes rau taw tes rau cov khoom siv kho qhov muag. Muab 1-8 E1 interfaces, thawj thiab thaub qab fiber ntau optical interface connector, 1-4 lub cev kev sib cais 10/100M Fast Ethernet interface (ywj siab plaub-xaim ceev 100M, tag nrho bandwidth yog 4 * 100M), nrog rau ob lub lag luam nthuav dav interface. 2 Kev pabcuam txuas ntxiv tuaj yeem siv tau raws li RS232 / RS485 / RS422 asynchronous cov ntaub ntawv, daim ntawv thov yog hloov tau yooj yim. Kev xaiv ib lub xov tooj pabcuam digital, daim ntawv thov yog hloov tau yooj yim. Nrog lub suab tswb muaj nuj nqi, tag nrho ruaj khov, txhim khu kev qha, tsis tshua muaj zog noj, kev koom ua ke siab, me me.
