Mini media converter for copper-to-fibre links

The Allied Telesis AT-MMC2000/LC-960 converts between 10/100/1000Base-T RJ-45 and LC duplex fibre at 850 nm. It supports 50/125 µm and 62.5/125 µm multimode cable up to 500 m. The unit also performs rate conversion, so differing copper and fibre speeds can interoperate. It suits installers extending LAN segments over fibre in commercial buildings.

Fanless operation from 0 °C to 50 °C

The converter runs without a fan across the full 0 °C to 50 °C (32 °F to 122 °F) range and 5 % to 95 % relative humidity non-condensing. A 12 VDC locking power jack prevents accidental disconnects. Store-and-forward switching with a 2 K MAC table keeps latency predictable. Power draw stays low enough for standard wall-wart supplies.

Wall-mount kit and Smart MissingLink

An optional MMCWLMT bracket lets the device mount on a wall or DIN rail. Smart MissingLink propagates link-loss status between the copper and fibre ports so upstream switches detect failures quickly. Far End Fault on the fibre port adds another failure signal. LED indicators show link and activity per port, and 10 K byte jumbo frames pass transparently.

Questions about this item

How do I install the AT-MMC2000/LC-960 and which step is often missed?

Connect the 12VDC power supply to the locking jack, insert LC fiber and RJ-45 cables, then secure the unit with the MMCWLMT wall-mount kit; the step often missed is snapping the locking power jack fully to prevent accidental disconnects.

What maintenance or replacement will the AT-MMC2000/LC-960 need later?

The 12VDC power supply and LC fiber patch cords are the only field-replaceable parts; the converter itself has no moving components or user-serviceable internals.

What limit appears first on the AT-MMC2000/LC-960 under sustained load?

The 500 m multimode fiber reach at 850 nm and the 0 °C to 50 °C operating temperature range are the first constraints under continuous traffic.
