10/100BASE-TX to 100BASE-FX Media Converter
2. Overview
2.1 Introduction
LBMC300-MMST and LBMC300-MMSC converters provide one channel for media
conversion between 10BASE-T/100BASE-TX and 100BASE-FX. They can be used as
a standalone device or with a standard 19” chassis as shown in Figure 2-1.
An LBMC300-MMST or LBMC300-MMSC media converter provides one TX port
and one FX port. For the FX port, you can use multimode fiber cable with an SC or
ST connector, depending on the model. The TX port uses one RJ-45 connector and
autosenses the 10-/100-Mbps speed.
Port settings are easy via a DIP (Dual Inline Package) switch on the rear panel of the
module.

NOTE: The rack (part number LB300A-RACK) is available separately.
