Allied Telesis AT-DMC100/SC-90 MEDIA CONVERTER 100T 100FXSC FED

Product Overview

The Allied Telesis AT-DMC100/SC-90 is a TAA-compliant standalone Fast Ethernet media converter that bridges 100Base-TX copper (RJ-45) to 100Base-FX fiber using an SC duplex connector. Part of Allied Telesis’ compact DMC series, this converter fits in the palm of your hand at just 1.25” wide × 3.6” deep × 0.85” high, making it ideal for desktop and field deployment where space is at a premium. The SC connector version is the ideal choice for networks already cabled with SC-terminated multimode fiber, enabling transparent 100Mbps copper-to-fiber extension with no configuration required. TAA compliance (FED suffix) qualifies this unit for federal and government procurement.

Product Description

The Allied Telesis AT-DMC100/SC-90 media converter with SC fiber connector converts 100Base-TX copper Ethernet to 100Base-FX multimode fiber at up to 2km distance, with zero configuration required out of the box. The SC duplex connector — distinguishing this unit from the LC and ST variants in the DMC100 family — makes it the right choice when your fiber cable plant is already terminated with SC connectors, which remain among the most common in enterprise and campus infrastructure. Auto MDI/MDI-X on the copper RJ-45 port eliminates the need for crossover cables regardless of whether you’re connecting to a switch, hub, or PC. The Smart MissingLink (SML) feature monitors both the copper and fiber network segments and disables the opposite port when a link failure is detected, ensuring that network monitoring tools and spanning tree protocols receive accurate link-state notifications. Smart Link Restoration automatically restores links after power failures or interruptions without manual intervention. The DMC100/SC-90 can be powered via the included Micro USB to USB cable (from a PC, laptop, or USB charger) or via an optional AC/DC adapter — eliminating dedicated power circuit requirements in many installations. RoHS compliant and wall-mountable using the optional AT-DMCWLMT bracket. Available from Creation Networks at creationnetworks.net.

Key Features

• 100Base-TX to 100Base-FX/SC Conversion — Bridges copper RJ-45 and SC duplex multimode fiber at 100Mbps Fast Ethernet speeds.
• SC Duplex Fiber Connector — Connects to existing SC-terminated multimode fiber infrastructure; choose /LC or /ST variants for other connector types.
• Auto MDI/MDI-X — Eliminates crossover cable requirements; connects to any copper device without reconfiguration.
• Smart MissingLink (SML) — Detects link failures and propagates link-down state across both ports for accurate network monitoring.
• Smart Link Restoration — Automatically restores links after power or connectivity interruptions without manual reset.
• USB or AC Power — Powers from Micro USB to USB cable (included) or optional AC/DC adapter; no dedicated power circuit required.
• TAA Compliant (FED) — Eligible for federal and government procurement under GSA Schedule and related vehicles.

Typical Applications

• Extending 100Mbps copper Ethernet to SC-terminated multimode fiber segments
• Connecting SC fiber runs to copper-only switches or network equipment
• Federal and government network installations requiring TAA-compliant media converters
• Desktop or field deployments where compact size and USB power simplify installation
• Any environment where existing fiber cabling uses SC connectors

Technical Specifications

Frequently Asked Questions

Q: What is the difference between the AT-DMC100/SC-90, /LC-90, and /ST-90?

All three are identical 100Mbps Fast Ethernet media converters. The only difference is the fiber connector: /SC-90 uses an SC duplex connector, /LC-90 uses an LC duplex connector, and /ST-90 uses an ST bayonet connector. Choose the model that matches your existing fiber terminations.

Q: Does this converter require any configuration?

No. The AT-DMC100/SC-90 is plug-and-play with auto-negotiation and auto MDI/MDI-X. Simply connect the copper and fiber cables and it operates immediately.

Q: What fiber cable type does the SC port support?

The AT-DMC100/SC-90 supports 50/125µm and 62.5/125µm multimode fiber cable with SC connectors.

Q: Can it be wall-mounted?

Yes. The unit is compatible with the optional AT-DMCWLMT wall-mount bracket accessory (sold separately).

Q: Does this converter pass IEEE 802.1Q VLAN tags?

Yes. The DMC100/SC-90 is fully transparent to 802.1Q VLAN-tagged packets, making it compatible with modern managed switch infrastructure.
