Fiber ConnectionsThe Allied Telesis range of Fast Ethernet media converters provide a complete family of conversion devices, allowing users to extend the size of UTP and multi-mode fiber networks with the use of single-mode fiber cabling. Supporting SC connected single-mode fiber, these converters can be used to extend networks up to a distance of 40km.Auto-negotiation and MissingLink™When connecting media converters to autonegotiating Fast Ethernet switches, these mediaconverters will automatically connect the link in either full or half-duplex mode, allowing the linkto be established with the greatest bandwidth. Alternatively, the MissingLink feature allowsaccurate reporting to network management systems as well as allowing devices withredundant link capability to be inter-connected with these media converters, as a failure in onefiber link will be signalled to the switch, allowing the second link to become active.Simple InstallationThe media converters allow the installer to test the integrity of fiber connection, by forcing theconverters to communicate over the fiber cable. This Link Test feature allows installers to checkfor cable faults without the need for expensive fiber-optic test equipment.Standalone or Rack-mountEach small media converter is powered by an external power supply unit for use in standaloneapplications.Where multiple media converters are being used, up to 12 standalone devices canbe inserted into a low-cost rack-mount chassis, allowing all the converters to be powered by asingle internal power supply. In critical applications, a second load sharing internal power supply can be installed into the rackmount chassis.Hassle Free SupportAllied Telesis Fast Ethernet media converters offer free technical support, ensuring troublefreeinstallation.
