Chapter 2: Overview
2. Overview
2.1 Introduction
The Pure Networking Fast Ethernet Media Converters connect a 10/100BASE-TX
network segment and a 100BASE-FX network segment. Use these units to join a
10/100BASE-TX segment to a 100BASE-FX segment on your network, or use them
in pairs to extend the 328-foot (100-m) distance limitation of copper based
Ethernet.
The converters also feature LFP (Link Fault Passthrough, as described in Section 5.3).
Two converter models are available:
• LHC201A: This fiber SC media converter transmits/receives data by 1310-nm
short-wave laser over multimode fiber.
• LHC202A: This fiber SC media converter transmits/receives data by 1310-nm
short-wave laser over single-mode fiber.
2.2 Features
• Complies with 802.3u 10/100BASE-TX and 100BASE-FX standards.
• Provides one SC connector and one RJ-45 connector.
• Supports autonegotiation of duplex mode on the twisted-pair port.
• Supports autonegotiation of 10/100 Mbps and auto MDI/MDI-X for the
twisted-pair port.
• Supports Link Fault Passthrough (LFP) and Far End Fault (FEF) functions.
• Extends fiber distance up to 2 km for multimode fiber and 20 km for single-mode
fiber.
• Easy-to-view LED indicators provide status to easily monitor network activity.
• Uses an external power supply (included).
