CFM3400 Bridge Media Converter
Fast Ethernet 10/100Base-TX (RJ-45)
To 100Base-FX (ST/SC)
User’s Manual
(620-0591-010)
1. Overview
IEEE 802.3u 100Mbps Fast Ethernet supports two types of media, 10/100Base-TX and
100Base-FX, for network connection. Link Fault and Pass Through (LFP) feature
enhances the TP-Fiber link integrity and conformity. Either one of TP or Fiber port is
in link-fail state, the LFP converter forces the other port to be at link-disabled state.
The TP-Fiber converter can be used as a standalone unit or as a slide-in module to
the 19” converter rack, which can hold up to 10 units, at a central wiring closet.
