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).

Black Box Pure Networking Fast Ethernet Media Converters, LHC201A Overview Introduction, Features, What’s Included

LHC201A, Pure Networking Fast Ethernet Media Converters, LHC202A specifications

The Black Box LHC202A and LHC201A are essential components in modern networking solutions, particularly for businesses looking to enhance their connectivity and streamline data transmission over various media types. These fast Ethernet media converters are designed to facilitate high-speed data transfer between different network media, such as fiber optic and copper cabling, ensuring seamless communication in diverse environments.

The LHC202A model is particularly versatile, providing a dual-function design that includes both 10/100BASE-TX and 100BASE-FX interfaces. This feature allows users to easily convert signals between twisted pair copper cabling and fiber optic networks. With support for multi-mode fiber up to 2 kilometers and single-mode fiber up to 30 kilometers, the LHC202A offers flexibility for various configurations and distances, making it ideal for both local area networks (LANs) and wide area networks (WANs). The unit also supports automatic data rate detection, adapting seamlessly to the network's configuration without the need for extensive manual adjustments.

In contrast, the LHC201A focuses on providing a more compact and cost-effective solution for simple networking needs. It also features a 10/100BASE-TX to 100BASE-FX conversion, similar to the LHC202A. However, the LHC201A is typically aimed at users who require a reliable yet straightforward media conversion without additional features like redundancy. It is particularly useful in scenarios where space is at a premium or budgets are constrained, allowing small to medium-sized businesses to implement essential networking upgrades without incurring excessive costs.

Both models incorporate advanced technologies that ensure efficient data handling and robust performance. They are equipped with features such as LED indicators for monitoring link status and data activity, power failure notifications, and a durable design that allows for mounting in various environments. The ability to handle a wide range of network traffic while minimizing data loss and interruptions is critical in today’s fast-paced digital landscape.

In summary, the Black Box LHC202A and LHC201A media converters provide businesses with reliable, efficient, and flexible options for managing their networking needs. Their array of features ensures that users can optimize their network performance, whether through the advanced capabilities of the LHC202A or the straightforward application of the LHC201A. These converters are vital tools in enhancing connectivity and achieving high-speed data transfer across various network infrastructures.
