Product Name:Fiber Network Switches
Excellent industrial-level - anti-thunder, anti-static which always ensure sable transmission.
Terminal power supply at DC 10-58V.
Two independent power supply circuits.
It adopts fanless which does not need
additional cooling equipment.
It can meet the requirements of different
application scenes
In the case of intelligent traffic scene, high-definition camera increases the data volume and increases
the pressure of network bandwidth.USR-SDR021 unmanaged industrial ethernet switch supports 100-megabyte rate
to handle heavy traffic through smoothing.It reduce the construction cost.
