2.5G GPON C ntxiv rau SFP 20km
■SFP, luv luv rau Daim Ntawv me me-qhov tseem ceeb Pluggable, aka Mini-GBIC, yog lub compact optical transceiver module siv hauv kev sib txuas lus kho qhov muag. SFP transceiver modules yog tsim los txhawb SONET / H, Fast Ethernet, Gigabit Ethernet, Fiber Channel thiab lwm yam qauv kev sib txuas lus. Wanglink tsim thiab muab ntau yam ntawm SFP transceiver modules uas tuaj yeem hloov kho.
■ Ib leeg-fiber bidirectional kub-swappable SFP nrog SC / UPC interface
■ Txog 2.5Gbps kev khiav hauj lwm tus nqi
