The NSM-206FCS (SC Connector; Single-mode) is an unmanaged, 4-Port Industrial 10/100 Base-T(X) with Dual 100 Base-FX Switch that secures data transmission by using fiber optic transmission to provide immunity from EMI/RFI interference. It uses Ethernet for transmitting a signal up to 15 Km, and is the perfect solution for applications where transmission must be protected from electrical exposure, surges, lightning or chemical corrosion. The NSM-206FCS operates at full duplex mode. In full duplex mode, range is 15 Km with 8.3/125, 8.7/125, 9/125 or 10/125 μm fiber cables. The NSM-206FCS can extend your LAN in a daisy chain configuration. Please refer to User's Manual. NSM-206FCS provides two power inputs that can be connected simultaneously to live DC power sources. If one of the power inputs fails, the other live source acts as a backup to automatically support the NSM-206FCS's power needs.
