The number of optical switch ports ranges from 8 ports to 96 ports, or even more, including intelligent switching hardware, so that any two points in all ports of the switch can be connected. Optical switches can be cascaded and stacked through e-ports (expansion ports). This method can expand the optical network to thousands of nodes, and the stack of switches can reach 239 at most.

ZXD216G-SFP an hardened 16-port Industrial Ethernet Switch, provides non-blocking wire-speed performance in harsh industrial environment. It provides 16-port 10/100/1000BASE-TX RJ45 copper interfaces +2 Port 10/100/1000 SFP delivered in an IP40 rugged, strong case with redundant power system. Its slim case is suitable for such applications as surveillance system deployments, control management and wireless service in climatically demanding environments with wide temperature range from -40℃ to 80℃. 

The ZXD216G-SFP series provides the flexibility to all kinds of 10/100Mbps Ethernet Media on RJ-45 port and performs highly stable fiber performance.

The ZXD216G-SFP series is packaged in a compact IP40 case that allows either DIN rail or panel mounting to have efficient usage of cabinet space. It provides an integrated power supply with a wide range of voltages for worldwide operation. It also offers dual-redundant, reversible polarity 12V DC to 52V DC power supply inputs for high availability applications requiring dual or backup power inputs.
