4 ports and 2 SFP ports Gigabit ethernet optical fiber switch: 

It belonged to the switch of 2000series,2 ports for 1000 Base SFP ,LC or SC, single mode and multi mode, single fiber

and dual fibers can be selected;the max transporting distance can reach 120km, It adopts high quality network switch chip,

and its all ports support non-blocking, across the packet forwarding; it is very suitable for data communication,video monitoring

and relay transmission equipment during to flexible and simple usage.
