Fast Ethernet Media Converter for UTP-to-Fibre

The Allied Telesis AT-MC102XL-90 converts 100Base-TX copper links to 100Base-FX multi-mode fibre at 1310 nm. It supports a single RJ-45 port and a duplex SC port for distances up to 1.24 mile. The unit is rack-mountable or wall-mountable with a compact 1.00" x 4.10" x 3.70" form factor.

Verify Copper and Fibre Compatibility Before

Confirm the existing network runs 100Base-TX over UTP cabling and that the fibre plant uses multi-mode duplex SC connectors at 1310 nm. The converter requires an external power adapter operating at AC 120 V and 50/60 Hz. Ensure the link distance does not exceed the stated 1.24 mile limit for reliable operation.

Low Power Draw and Silent Operation in Normal Use

The device draws 6 Watt during operation and uses an external power adapter, keeping the converter itself free of active cooling. Status indicators show Link OK, Power, Receive and Test mode for quick diagnostics. The lightweight 0.65 lb chassis produces no audible noise under typical network loads.
