The FR485 is a RS-485 to fiber optic convertor module available as a single fiber pair output repeater or dual fiber pair output repeater. The FR485 uses OPTEK's b 850nm, transmitter and receiver with the “ST” connector receptacles for 62. 5-125mm (50/125mm) fiber optic cables. A verification email has been sent to {0}. These systems support various field bus protocols, including MODBUS, MODNET-1/SFB, BIT-BUS, SAIA-S-BUS. The Westermo range of fibre optic modems ensures reliable communications over multimode and single mode fibre optic cables. With transparent operation, our fibre optic modems act as converters for serial RS-232, RS-422, RS-485 and PROFIBUS protocols. It converts electrical RS-485 signals into optical signals, ensuring high-speed, interference-free data transmission. These devices are independent from the serial protocol and they are adapted for Modbus, Modbus+ and IEC131.
