NSM-206FT - 4 Port 10/100 Base RJ 45 with 2 Port Fiber Optic, ST Connector, Multi-Mode, Metal Case
by ICP DAS

The NSM-206FT (ST Connector; Multi-mode) is a 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 is used Ethernet for transmitting a signal up to 2 Km(6,600 ft), and is the perfect solution for applications where transmission must be protected from electrical exposure, surges, lightning or chemical corrosion. The NSM-206FT operates at either half or full duplex mode. In full duplex mode, range is 2km with 62.5/ 125μm fiber cables; in half duplex mode, range is 412m with 62.5/ 125μm fiber cables. The NSM-206FT can extend your LAN in a daisy chain configuration. Please refer to manual. NSM-206FT 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-206FT's power needs.
