4E1+4FE PDH Fiber Multiplexer Saukewa: JHA-CPE4F4

Dubawa

Wannan na'urar tana samar da 1-4*E1 interface, 1-4*10M/100M Ethernet interface (Wire Speed ​​100M) da 2 fadada dubawa. 4 * Ethernet dubawa shine mai sauyawa, yana 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.
