Introduction

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

Overview of the Converter
MC100CM and MC110CS are Fast Ethernet Media Converters. MC111CS and MC112CS, the WDM Fast Ethernet Media Converters, adopt WDM (Wavelength Division Multiplexing) technology which increases the information carrying capacity of fiber via transmitting and receiving multiplex signals at different wavelengths on a single strand cable. You can save half cabling cost 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 the section 1.5.3.

Conventions
The Converter mentioned in this guide stands for Fast Ethernet Media Converters or the WDM Fast Ethernet Media Converters without any explanations. 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. Their differences are in the table in Section 1.4.

Appearance Indication

LED Indicators
The converter has LED indicators which can provide a real-time report. When you take a look at these indicators, you will know what’s happening on your network. For details, please refer to the table as shown below.

connector.
Off| There’s no valid link.
TP| SPD| On| The TP port is connected to 100Base-Tx
Off| The TP port is connected to 10Base-Tx device or no connection.
FDX/Col| On| The TP port is operating in Full-Duplex.
Flashing| There’s a collision.
Off| The TP port is operating in Half-Duplex mode.
Link/Act| On| There’s a valid link.
Flashing| The converter is receiving or transmitting data from the TP port.
Off| There’s no connection on the TP port.

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

Note:

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

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), TP port and FX port of the same converter will inform 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. The procedure will be illustrated as shown below.

If link fail happens on TP port (A), the FX port (A) sends 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

Installation Guide

Fast Ethernet Media Converter

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

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

WDM Fast Ethernet Media Converter

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

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

Configuration

In order to effectively expand a Fast Ethernet network, you can use the converter like the following examples:

1. Place two converters back to back between the following end devices.
   

2. Another effective application is to place one converter directly between a 10/100Base-TX device and a 100Base-FX device.
   

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

1. 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.
2. Connection of two Converters or a Converter and a 100Base-FX Device.
   • Use a SC fiber cable to connect the two Converters’ SC connector or the SC connecter of a Converter and a 100Base-FX Device.
3. Turn on the power.
