D-Link 100Base-TX to 100Base-FX Single-mode Fiber (SC) Media Converter | DMC-520SSC

Media converters convert signals that are transmitted from one type of media to another so that they can be transmitted over a different type of media. This series of media converters converts 10/100/1000 Mbps copper ethernet to a 100/1000 Mbps fibre optic connection connection.This allows you to expand your network by connecting longer distance,cables between devices that are otherwise connected with short distance Ethernet cables, such as Cat.6 twisted-pair cables.
