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 par ty 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-T X segment to a 100BA SE-F X 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 /100BA SE-TX and 100 BASE-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 ) func tions.
• Extends fiber distance up to 2 km for multimode fiber and 20 km for single-mode
fi ber.
• Easy-to-view LED indicators provide status to easily monitor network activity.
• Uses an external power supply (included ).
