4E1+4FE(Karantiil jireed)JHA-CPE4WF4

PDH Fiber Multiplexer

Dulmar

Qalabkan taxanaha ah waa shirkaddu waxay horumarisay gudbinta fiber-ka PDH ee u heellan VLSI oo la sameeyay iyadoo lagu salaynayo dhibic si loo tilmaamo qalabka gudbinta indhaha. Bixi 1-4 E1 interfaces, xiriiriyaha aasaasiga ah iyo kaydka fiber optic interface, 1-4 go'doomin jireed 10/100M Fast Ethernet interface (xawaaraha afar-xawaaraha madax-bannaan ee 100M, wadarta guud ee bandwidth waa 4 * 100M), iyo sidoo kale laba interface ballaarinta ganacsiga. 2 Interface adeeg dheerad ah waxaa loo isticmaali karaa sida RS232 / RS485 / RS422 xogta asynchronous, codsigu aad ayuu u dabacsan yahay. Ikhtiyaarka mid ka mid ah telefoonka adeegga dhijitaalka ah, codsigu waa mid aad u dabacsan. Iyada oo shaqeynta qaylo-dhaanta dhawaaqa, dhammaan xasilloonida, la isku halleyn karo, isticmaalka awoodda hoose, isdhexgalka sare, cabbir yar.
