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 2 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 connector for your fiber optic cable and one Ethernet RJ45 port (Auto MDI/MDIX) for your 100BaseTX 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 x W x H) is: 119mm x 85mm x 26mm

Front Panel

The Front Panel of the

ComNet CWFE2SC(M)(S)2 consists of one RJ45

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.

Ports



RJ45 Port (Auto MDI/MDIX): the Ethernet RJ45 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 real-time 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.

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.

Rear Panel

The rear panel contains a power socket, which accepts 8–24 VDC @ 220mA.

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 ft.) 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 um multimode fiber cable. You can connect two devices up to a 2-kilometer

(6,562 ft.) distance.

6

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.
