FCC and IC RFI Statements

FEDERAL COMMUNICATIONS COMMISSION AND INDUSTRY

CANADA RADIO FREQUENCY INTERFERENCE STATEMENTS

Class B Digital Device. This equipment has been tested and found to comply with

the limits for a Class B computing device pursuant to Part 15 of the FCC Rules.

These limits are designed to provide reasonable protection against harmful

interference in a residential installation. However, there is no guarantee that

interference will not occur in a particular installation. This equipment generates,

uses, and can radiate radio frequency energy, and, if not installed and used in

accordance with the instructions, may cause harmful interference to radio

communications. If this equipment does cause harmful interference to radio or

telephone reception, which can be determined by turning the equipment off and

on, the user is encouraged to try to correct the interference by one of the following

measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

• Connect the equipment into an outlet on a circuit different from that to which

the receiver is connected.

• Consult an experienced radio/TV technician for help.

Caution:

Changes or modifications not expressly approved by the party responsible for

compliance could void the user’s authority to operate the equipment.

To meet FCC requirements, shielded cables and power cords are required to

connect this device to a personal computer or other Class B certified device.

This digital apparatus does not exceed the Class B limits for radio noise emission

from digital apparatus set out in the Radio Interference Regulation of Industry

Canada.

Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les

limites applicables aux appareils numériques de classe B prescrites dans le

Règlement sur le brouillage radioélectrique publié par Industrie Canada.

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).
