Allied Telesis AT-MC101XL-20 Fast Ethernet copper/fibre network segments Optical Transmission Module

The Allied Telesis AT-MC101XL-20 is a genuine unmanaged Fast Ethernet media converter, converting a 100BASE-TX copper port to a 100BASE-FX fibre port so that copper and fibre network segments can be bridged directly. As a standalone converter it requires no configuration, making it straightforward to deploy at the boundary between a copper LAN segment and a fibre backbone or long-distance run where copper cabling alone wouldn’t reach. Media converters of this type were a routine, low-cost way to extend Fast Ethernet networks beyond copper’s 100-metre distance limit while keeping both ends of the link electrically isolated. Genuine units remain useful for maintaining or extending existing fibre-copper conversion points on legacy Fast Ethernet infrastructure still in service. Specifiers should confirm exact fibre-connector and distance requirements before ordering. Tech-Star (UK-based, shipped worldwide) stocks components to support ongoing network maintenance projects.
