1.1 Properties
The Modular Managed Switch (Modular Managed Switch System - MMS) is an Ethernet
switch, which is suitable for industrial use and consists of a head station, extension
modules, and interface modules. The head station and extension modules contain the
entire Ethernet switching technology. Interface modules provide the interface to the
desired physical transmission method. An extension module can be used to extend the
head station from eight ports to 16 ports, and the use of two extension modules gives a
maximum of 24 ports. The desired transmission medium can be freely selected using the
various interface modules.

Future-Proof Networks for the Highest Possible Requirements
Transmission method 10/100 Mbps polymer/HCS fibers
Easy to assemble polymer fibers can now also be used for Ethernet. This cost-effective
fiber optic technology can cover distances of up to 50 m. This provides cost savings both
during installation and for maintenance when replacing mechanically damaged fiber optic
cables.
HCS fiber technology is available for distances of up to 100 m.
