10Gb Fiber Ethernet Switch – ENTU 78

One Copper Interface: Comply 3

ENTU 783 series is a so-called 10G fibre optical switch. The interface of ENTU 783 includes one 10G Ethernet port and three Optical SFP+ ports. With the physical quick setting dip switch on the back panel, the user can easily select from MDC mode to the Ethernet Switch mode. To interoperate with different line rates, it supports flow control which can send pause frames dynamically to control the transmitting rate so it won’t be overwhelmed with data packets.with IEEE 802.3u/ 802.3ab/ 802.3bz/ 802.3an standard as 100Base-Tx/ 1000Base-T/ NBase- T/ 10GBase-T (100M/1G/2.5G/5G/10G), Auto Negotiation
