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.

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

• 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.

• Make sure that the CAT5 twisted pair cable between the 10/100BASE-TX device
and the converter is less than 328 feet (100 meter s) long.
• Connec t one end of the CAT5 t wisted pair cable to the R J- 45 jack on the
converter and the other end of the cable to the RJ-45 jack on the 10/100BASE-TX
device.

5.3 Link Fault Pass Through Function
In common situations, when one side of the link fails, the other side continues
transmitting packets and waits for a response that never arrives from the
disconnected side.
With the Link Fault Passthrough function enabled (optional with switch LFP), the TP
port and FX port of the same converter will tell each other the fault link status so
that when one side of the link fails, the other side will force the link to shut down as
soon as noticed. See Figure 5 -3.

If link fail happens on TP port (A), the FX port (A) sends a non-idle pattern to notice
the FX port (B ). The FX port (B) then forces it s TP port (B) to link failed after
receiving the non-idle pattern. Link status LED will also be off for both converters
