2. Overview
2.1 Introduction
The Compact Media Converter provides two conversions between
10/100/1000BASE-T twisted pair and 100/1000BASE-SX/FX fiber. This device
automatically negotiates speed and duplex on the copper port and the fiber
100/1000 Mbps, full-duplex port.
The Compact Media Converter, SFP (LGC5150A) is an SFP port-based model that
includes two 10/100/1000 Mbps RJ-45 connectors and one SFP port. It supports
MSA-compliant 1000- or 100-Mbps SFPs. A DIP switch enables LFPT (Link Fault
Passthrough), a diagnostic feature for troubleshooting a fault fiber. An SFP version
is available; both support jumbo frames up to 10240 MTU. The media converter
will detect the SFP and run over single-mode fiber or multimode fiber at the
speed for which the SFP was designed. Compatible SFPs include the
LFP401–LFP403 and LFP411–LFP414 (see Table 2-4).
The Compact Media Converter, TX/FX (LGC5151A) is a fixed fiber transceiver
model that includes two 10/100/100 Mbps RJ-45 connectors and one
1000-Mbps SC fiber connector. The LGC5151A supports dual-strand multi-mode
fiber. A DIP Switch enables LFPT (Link Fault Passthrough), a diagnostic
feature for troubleshooting a fault condition on a segment.
The Compact Media Converter, TX/FX (LGC5152A) is a fixed fiber transceiver
model that includes two 10/100/100 Mbps RJ-45 connectors and one
1000-Mbps SC fiber connector. The LGC5152A supports dual-strand single-mode
fiber. A DIP Switch enables LFPT (Link Fault Pass-Through), a diagnostic feature for
troubleshooting a fault condition on a segment.
