Media converters a cost-effective approach for adding fibre to networks

3 July 2002 Computer/Embedded Technology

Contemporary Controls' industrial Ethernet media converters in its CTRLink family are ideal for those industrial applications requiring conversion between copper to fibre media. Appearing as transparent devices in a compact size, media converters are a trouble-free and affordable approach for adding fibre to a network.

The company's media converters are available in three models, supporting either ST or SC-style connectors. The EIMC-10T/F operates at 10 Mbps and meets the signalling requirements for 10BASE-T and 10BASE-FL. The EIMC-100T/FT is a 100 Mbps device that converts 100BASE-TX twisted-pair signals to 100BASE-FX fibre-optic signals and uses ST fibre-optic connectors. The EIMC-100T/FC is a similar product but uses SC-style fibre-optic connectors.

The front of each model provides a DIP switch for selecting the operational mode - be it full-duplex mode, half-duplex mode or transparent mode. Power, link and activity LEDs are provided for convenient front panel diagnostics. A power LED glows green when power is applied. Each port has two LEDs. 'A' flashes green as data is transferred; 'L' indicates the data rate by colour - green for 100 Mbps and yellow for 10 Mbps. All models feature a miniature enclosure and accept a wide range of low-voltage AC or DC power. Power consumption is less than 4 W and all models are DIN-rail mounted.
