100 Mbps fibre-to-copper converter

The Allied Telesis AT-DMC100/SC-90 is a desktop media converter with one RJ-45 port and one SC port. It bridges 100Base-TX twisted-pair and 100Base-FX optical fibre segments at Fast Ethernet speed. The unit provides two ports in total for linking copper and fibre networks.

Installers extending a 100 Mbps link over fibre

Suitable for network technicians who need to connect a copper switch or device to a multimode or single-mode fibre run using SC connectors. Not intended for gigabit or 10 Gbps links, for SFP-only slots, or for installations that require Power over Ethernet or managed switching features.

SC connector for 100Base-FX fibre

The single SC port accepts standard duplex SC patch cords for 100Base-FX operation. Verify that the remote endpoint also uses 100Base-FX optics and matching fibre type before deployment.

Questions about this item

Does the AT-DMC100/SC-90 include both the RJ-45 and SC cables, or must they be purchased separately?

The converter provides one RJ-45 port and one SC port for 100Base-TX and 100Base-FX connectivity; twisted-pair and fibre patch cables are not included and must be sourced separately.

The model name includes 90 — does that refer to a 90 km fibre reach or a different specification?

The unit supports 100Base-FX over an SC interface; the 90 in the model number is a part-code identifier and does not indicate a 90 km transmission distance.

When installed in a live network, what does the 100Base-FX rating actually deliver for throughput and distance?

The transceiver operates at Fast Ethernet speeds of 100 Mbps over multimode fibre using the SC connector, with reach determined by the fibre grade and link budget of the connected switch.
