Fiber Connections

The Allied Telesis range of Fast Ethernet media
converters provides a complete family of
conversion devices, allowing users to extend the
size of UTP networks with the use of fiber
cabling. Suppor ting both SC and ST fiber
connectors, these converters can be used to
extend networks with up to 2km of multi-mode
fiber or 40km of single-mode fiber.

Auto-Negotiation and MissingLink™

The MissingLink feature enables the fiber optic
ports on the media converter to pass the ‘Link’
status of their connections to each other. When
the media converter detects a problem with
one of the ports, such as the loss of connection
to an end-node, the media converter shuts
down the connection to the other por t, thus
notifying the node that the connection has been
lost.

Simple Installation

All the media converters feature auto
MDI/MDI-X, allowing the converter to be
connected to either a PC, hub or switch with a
simple UTP cable. The media converters also
allow the installer to test the integrity of fiber
connection, by forcing the converters to
communicate over the fiber cable. This ‘Link Test’
feature allows installers to check for cable faults
without the need for expensive fiber optic test
equipment.

Standalone or Rack-mounted

Each small media converter is powered by an
external power supply unit for use in standalone
applications. Where multiple media converters
are being used, up to 12 standalone devices can
be inserted into a low-cost rack-mount chassis,
allowing all the converters to be powered by a
single internal power supply. In critical
applications, a second load sharing internal
power supply can be installed into the rack­mount chassis.

Hassle Free Support

Allied Telesis Fast Ethernet media converters
offer free technical suppor t, ensuring trouble­free installation.

Link Test

The link test is a fast and easy way for you to test the
connections between the media converter ports and the
end-nodes that are connected to the ports. If a network
problem occurs, you can perform a link test to
determine which port is experiencing a problem, and be
able to focus your troubleshooting efforts on the cable
