Chapter 1 Introduction

Thank you for choosing the MC100CM/MC110CS Fast Ethernet Media Converters or the MC111CS/MC112CS WDM Fast Ethernet Media Converters!

1.1 Overview of the Converter
MC100CM and MC110CS are Fast Ethernet Media Converters. MC111CS and MC112CS are WDM Fast Ethernet Media Converters, which adopt WDM (Wavelength Division Multiplexing) technology that increases the information-carrying capacity of fiber via multiplex transmit and receive signals at different wavelengths on single strand cable. You can save half the cabling costs when you use MC111CS and MC112CS instead of your original dual fiber converter.
The converter mediates between a 10/100Base-TX segment and a 100Base-FX segment. It is primarily designed for large, higher speed/bandwidth demanding workgroups that require expansion of the Fast Ethernet network.
The converter also features the LFP (Link Fault Pass-through) function, and for its procedure illustrates, please refer to section 1.5.3.

1.2 Conventions
The Converter mentioned in this guide stands for Fast Ethernet Media Converters or the WDM Fast Ethernet Media Converters without any explanation.
The TP port mentioned in this User Manual stands for the TX port without any explanations.

Note:
The four converters are sharing this User Guide. For the differences between them please refer to the table in section 1.4.

1.5.2 Switch

TP_AUTO: The TP port operates in Auto-Negotiation mode;
TP_DIS: The TP port operates in FORCE mode;

TP_100M: The TP port operates in 100Base-Tx;
TP_10M: The TP port operates in 10Base-T mode;

TP_FDX: The TP port operates in Full-Duplex mode;
TP_HDX: The TP port operates in Half-Duplex mode;

LFP_OFF: The Link Fault Pass-Through function is disabled;
LFP_ON: The Link Fault Pass-Through function enable.

Connect different devices, we suggest leaving the switches like these as shown below, otherwise, the Media Converter may not work normally.

The Mode Of The Device	Switch
TP:AUTO; LFP ON	TP AUTO, TP 100M, TP_FDX, LFP ON
TP:AUTO; LFP OFF	TP AUTO, TP 100M, TP_FDX, LFP OFF
TP:FORCE,100M,FULL; LFP ON	TP DIS, TP 100M, TP FDX, LFP ON
TP:FORCE,100M,FULL; LFP OFF	TP —DIS, TP —100M, TP FDX, LFP OFF
TP:FORCE,100M, HALF; LFP ON	(TP DIS or TP AUTO), TP 100M, TP HDX, LFP ON
TP:FORCE,100M, HALF; LFP OFF	(TP —DIS or TP AUTO), TP 100M, TP HDX, LFP OFF
TP:FORCE,10M,FULL; LFP ON	TP DIS, TP 10M, TP FDX, LFP ON
TP:FORCE,10M,FULL; LFP OFF	TP DIS, TP 10M, TP FDX, LFP OFF
TP:FORCE,10M, HALF; LFP ON	(TP DIS or TP AUTO), TP 10M, TP HDX, LFP ON
TP:FORCE,10M, HALF; LFP OFF	(TP DIS or TP AUTO), TP 10M, TP HDX, LFP OFF

Note:

We suggest leaving the switches on TP_AUTO, TP_100M, TP_FDX, and LFP_ON because this configuration is suitable for lots of situations.
You have to reset the converter after configuring the switches.

1.5.3 Link Fault Pass-Through Function
In common situations, when one side of the link fails, the other side continues transmitting packets and waiting for a response that never arrives from the disconnected side.
With the Link Fault Pass-Through function enabled (optional with switch LFP), the TP port and FX port of the same converter will inform each other of 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. The procedure will be illustrated as shown below.

If a link failure 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 its TP port (B) to link failed after receiving the non-idle pattern. Link status LED will also be off for both Converters and Devices as shown below.

	Link LED
Device A	Off
Device B	Off
	FX_LFP	FX_Link/Act	TP_Link/Act
Converter A	On	Off	Off
Converter B	On	Off	Off

Chapter 2 Installation Guide

2.1 Fast Ethernet Media Converter

The SC fiber connector of MC100CM transmits/receives data by 1310nm short wave laser on multi-mode fiber.
The SC fiber connector of MC110CS transmits/receives data by 1310nm short wave laser on single-mode fiber.

Transmits and receives data on different fibers

Note:
You have to use either two MC100CM connectors or two MC110CS connectors to cooperate.

2.2 WDM Fast Ethernet Media Converter

The SC fiber connector of MC111CS transmits data by 1550nm short wave laser while receiving data by 1310nm short wave laser on one single-mode fiber.
The SC fiber connector of MC112CS transmits data by 1310nm short wave laser while receiving data by 1550nm short wave laser on one single-mode fiber.

Transmits and receives data on the same fiber

Note:
You have to use MC111CS and MC112CS at the same time to cooperate.

Chapter 3 Configuration

In order to achieve the aim of effectively expanding a Fast Ethernet network, you can use the converter like the following examples:

Place two converters back to back between the following end devices. Note:
You should use two MC100CM Media Converters or two MC110CS Media Converters, or one MC111CS and one MC112CS to expand your network. The error will occur when you use other ways.
Another effective application is to place one converter directly between a 10/100Base-TX network and a 100Base-FX device.

3.1 Installation Procedure
Use a fiber cable to connect two converters, or connect a converter with a 100Base-FX Device.

Connection of a Converter and a 10/100Base-TX Device (HUB or Switch).
• Make sure that the length of the Cat.5 twisted pair cable between the 10/100Base-TX device and the converter is less than 100 meters.
• Connect one end of the Cat.5 twisted pair cable to the RJ45 jack on the converter and the other end of the cable to the RJ45 jack on the 10/100Base-TX device.
Connection of two Converters or a Converter and a 100Base-FX Device.
• Use an SC fiber cable to connect the two Converters’ SC connectors or the SC connecter of a Converter and a 100Base-FX Device.
Turn on the power.
