Introduction

The ComNet CWFE2SC(M,S)2 is a cost-effective solution for converting 10/100Base-TX electrical to and 100Base-FX fiber optic cable, It allows you to extend the distance of your 100Base-FX network up to 3 kilometers for multi-mode fiber or up to 30 kilometers for single-mode fiber. The ComNet CWFE2SC(M,S)2 gives you the option of choosing between the most popular fiber cabling connectors: SC/multi-mode fiber connector and SC single-mode fiber connectors. The CWFE2SC(M,S)2 module provides you with one fiber port for your fiber optic cable and one Ethernet RJ45 port (Auto MDI/MDIX) for your 100Base-TX copper cable connection. There are 4 DIP- switches to set the operation mode for UTP, Fiber ports and link loss forwarding function.

Hardware Description

Unit dimension (L × W × H) is: 119 × 85 × 26 mm

Front Panel

The Front Panel of the ComNet CWFE2SC(M,S)2 consists of one RJ-45 Port (Auto MDI/MDIX), 6 LED Indicators (UTP 100, LK/ACT, FDX/COL, Fiber LK/ACT, FDX/COL and PWR) and one fiber 100Base-FX Port.

Fast Fiber Conver ter Module - SC Model

Ports

RJ-45 Port (Auto MDI/MDIX): the Ethernet RJ-45 will auto-sense for 10Base-T or 100Base-TX connections. Auto MDI/MDIX means that you can connect to another switch or workstation without changing non-crossover or crossover cabling.

Fiber Port: This port is for 100 Base-FX connections.

LED Indicators

There are 6 diagnostic LEDs located on the Front panel of the media converter. They provide realtime information of system and optional status. The indicator includes Power, UTP 100, LK/ACT, FDX/COL, Fiber LK/ACT, FDX/COL. The following table provides description of the LED status and their meanings.

LED Color Status Description

PWR Green On Power On

100 Green On 100 Mbps UTP Speed

Off 10 Mbps UTP Speed

LK /ACT (UTP) Green On The unit is linking with its link partner.

Green Blinking The unit is transmitting or receiving packets from UTP devices.

Off No device attached

LK/ACT (Fiber) Green On The unit is linking with its link partner.

Green Blinking The unit is transmitting or receiving packets from FX devices.

Off No device attached

FDX/COL (UTP) Orange On The UTP port is operating in full-duplex mode.

Orange Blinking Collision of packets is occurring in the port.

Off Half-duplex mode or no device attached.

FDX/COL (Fiber) Orange On The fiber port is operating in full-duplex mode.

Orange Blinking Collision of packets is occurring in the port.

Off Half-duplex mode or no device attached.

DIP-switch

The DIP-switch is used to configure operation mode for LLF (Link Lost Forwarding) and operation mode for UTP/Fiber port. The default value of DIP switch is OFF.

SW No Status Description

1 ON UTP 100 Mbps Full Duplex Mode

OFF UTP Auto-Negotiate

2 ON Fiber in Half Duplex

OFF Fiber in Full Duplex

3 ON LLF Enable

OFF LLF Disable

4 ON Pure Converter mode

OFF Switch Converter mode

Link Lost Forwarding (DIP-Switch 3): When LLF is enabled, it allows UTP link failures to be reported to the fiber side and also allows a fiber link failure to be reported to the UTP side. Therefore, a link

loss forward feature is provided in both UTP and fiber side.

Pure Converter mode (DIP-Switch 4): When the pure converter mode is enabled (on), it operates with minimal latency. The transmission flow does not wait until the entire frame is ready, but instead it forwards the received data immediately after the data has been received. The UTP port should be forced at 100M in this application. When DIP-Switch is in Switch Converter mode (off),

the converter function is same as Switch Hub.

Note: Do not change the DIP-switch setting when UTP or fiber port is transmitting or receiving

data. It may cause some data errors. If you change the DIP-switch setting, please power off the converter and power it on again to make the setting effective.

Cabling

» For the Twisted-pair segment unshielded twisted pair (UTP) or shielded twisted pair (STP)

cabling can be used. The cable must comply with the IEEE 802.3u 100Base TX standard for Category 5. The cable between the converter and the link partner (switch, hub, workstation, etc.) must be less than 100 meters (328 feet) long.

» For the single mode fiber optic segment, use 9/125 μm single mode fiber cable. You can

connect two devices over a distance of 30 kilometers.

» For the multimode fiber optic segment use 50 or 62.5/125 µm multimode fiber cable. You can

connect two devices up to a 3 kilometer (2 mile) distance.

Problem Solving

» Check the DIP-switch configuration. It must be set in the same operational mode as the

corresponding link.

» Select the proper UTP/fiber optic cable to construct your network. The single-mode media

converter must use single-mode fiber optic cable. Please check that you are using the right cable.
