PDH Fiber Multiplexer

Dubawa

Wannan na'urar tana da ikon sarrafa kayan wasan bidiyo, yana ba da kariya ta hanyar fiber na 1 + 1, nuna nuni ga watsawar gani, nunin LCD, akan tushen ci gaban kamfaninmu na watsawar gani na PDH, yi amfani da VLSI na musamman da SNMP NMS.

Na'urar tana samar da 1-8 * E1 dubawa, 1-4 * 10 / 100M Ethernet dubawa (Wire gudun 100M) da 2 fadada dubawa. 4Channel Ethernet dubawa ne mai sauyawa dubawa, zai iya tallafawa VLAN. 2 fadada dubawa za a iya amfani da matsayin watsa tashar RS232/RS485/RS422 data asynchronous. Yana da sassauƙa sosai. Yana da aikin ƙararrawa. Aikin yana da abin dogara, kwanciyar hankali, da ƙananan amfani da wutar lantarki, babban haɗin kai, ƙananan ƙananan
