Optical Link Module (OLM)
Uses
With the PROFIBUS OLM (Optical Link Module), Version 3, PROFIBUS networks
can be implemented as bus, star and redundant ring structures.
can be implemented as bus, star and redundant ring structures.
The transmission rate of a fiber-optic path is not dependent on the distance and
can range from 9.6 Kbps to 12 Mbps.
can range from 9.6 Kbps to 12 Mbps.
OLMs can be used in system buses based on PROFIBUS, inter-building networks
with glass fiber-optic cables, mixed networks with electrical and optical segments,
large-span networks (road tunnel, traffic control systems), networks in which high
availability is required (redundant ring networks) etc.
