Carries a serial line 2 km over multi-mode fiber
A converter that moves RS-232, RS-422 and RS-485 lines onto multi-mode fiber optic cable. It links remote terminal units to a host computer or a SCADA controller, and because the medium is fiber, lightning, surge and electromagnetic interference stay off the line.

Key features
Fiber linkIt takes 50/125 µm, 100/140 µm and 200 µm multi-mode fiber cable.
Power budgetA 12.1 dB coupled power budget covers the loss on the fiber run.
Serial connectorsA DB9 male connector serves RS-232; a 6-pin terminal block serves RS-485 and RS-422.
Lightning protectionIt rates 600 W on the RS-232 lines and 1000 W on the RS-485/422 lines.
Transmission modeThe point-to-point link works in half and full duplex.
HousingThe 1 mm iron housing measures 100 × 86 × 26 mm, and the operating temperature runs from -20 °C to 70 °C.
Usage area: remote terminal units (RTU) · SCADA controllers · distributed data acquisition systems
