Optical Switch Modules (OSM, Version 2)
and Electrical Switch Modules (ESM) enable cost-effective set-up of switched networks at 100 Mbit/s.

The OSM and ESM serve to set up Industrial Ethernet networks using switching technology.
Connection of modules to one another (backbone) either using glass fiber optics or twisted pair cables at 100 Mbit/s
Connection of terminals or network segments using up to 6 twisted pair ports (as either 9-pin sub-D or RJ45 connections) at 10 Mbit/s or 100 Mbit/s
Bridging of distances of up to 18 km between 2 OSMs using single-mode fiber optic
Integrated redundancy manager allows rapid media redundancy, even for large networks
Simple network configuration and network extension without complicated design rules or parameterization
Prepared for SNMP and web-based management OSMs with 2 fiber optic ports are required to set up an optical ring.
Electrical rings are set up with 2 twisted pair ports on the ESM. The data rate in the ring is 100 Mbit/s, up to 50 OSMs or ESMs can be used per ring.
In addition to the 2 ring ports, OSMs and ESMs have another 6 ports (with a choice of ITP or RJ45 interfaces), to which either terminals or network segments can be connected.
Several rings can be connected to one another on a redundant basis using the integrated standby function.
The functionality of the modules can be monitored by the signalling contact. OSMs and ESMs are also prepared for integration into SNMP (Simple Network Management System) and Web-based network management systems.
The OSM and ESM can be upgraded and parameterized to the latest firm-ware versions via the serial port.
