Profibus Network Optical Link Modules

The OLM P22 and OLM G22 modules each have two optical Profibus interfaces using bayonet fiber optic connector (BFOC) technology and two electrical sub-D type interfaces.

Both modules allow two separate electronic Profibus segments to be integrated into one optical network structure, such as a redundant ring, line and star. The OLM P22 version supports plastic fiber-optic cable (FOC), the OLM G22 is designed for glass fiber-optic cable. They also offer a signal contact as a measurement terminal to monitor optical signal monitored.
