Fiber Optics

Fiber optic modems are often used in data communication systems to bridge long distances at high data rates. Fiber optic systems are particularly immune to electromagnetic interference and therefore very suitable for harsh industrial environments. Westermo products can transmit data at up to 12 Mbit/s over distances up to 80 km depending on the fiber type.

Point to point RS-232, PROFIBUS DP and RS-422/485 for point to point communication.

Fiber line sharing devices RS-232, PROFIBUS DP and RS-422/485 in multi-point, ring or redundant ring applications.

The new fiber optic modems, ODW-series, are available with 4 different transceivers: LC-2 Multimode 5 km, LC-15 Single mode 15 km, LC-40 Single mode 40 km, LC-80 Single mode 80 km.
