BH-C624  2*gigabit optical ports+8*GE
ports  Ethernet switch：
       BH-C624 is designed to convert the
Ethernet Signal to Optical, Configurate with 8*10/100/1000M Ethernet ports and
2*gigabit SFP optical ports.Use  to
achieve interconnection between more than one motherboard servers,repeaters,hubs,terminals
and multiple terminals.2 optical ports can make multi-points equipments
cascading.The Ethernet transmission distance of copper from 100 meters to 550
meters(multi-mode) or 100km(single mode).,Ensure in various harsh
environment(such as high temperature,low temperature,dust,electromagnetic
interference,etc.) of long-term,stable,reliable and safe use.

Main Feature：
1、2*gigabit optical ports(can be form chain network)and4/ 8
self-adaption 10/100/1000M Ethernet ports,the terminal support auto
reverse(Auto MDI/MDI-X).
2、Support
full duplex and half-duplex automatic negotiation type.
3、Support
automatic learning and update function of MAC address.
4、Comply
with IEEE802.3/802.3U/802.3x store and forward switching method.
5、Provide
IEEE802.3x(Flow control)under full duplex mode,provide Back-pressure folw
control under half-duplex mode.
