Allied Telesis AT-DMC1000/SC-90 – Gigabit Fiber Media Converter SC TAA

Product Overview

The Allied Telesis AT-DMC1000/SC-90 is an Allied Telesis 1000T to fiber media converter SC model, converting 1000Base-T Gigabit Ethernet copper to 1000Base-SX multimode fiber over an SC duplex connector in a compact desktop form factor. TAA compliant for U.S. federal procurement, this converter provides Gigabit fiber extension for enterprise networks, government facilities, and data centers where SC-connected multimode fiber infrastructure is already installed. The DMC series is recognized as one of the smallest and lowest-power media converters available, with optional wall-mount capability via the AT-DMCWLMT bracket (sold separately) for flexible installation in constrained spaces.

Product Description

The AT-DMC1000/SC-90 converts Gigabit Ethernet 1000Base-T copper (RJ-45) to 1000Base-SX multimode fiber using an SC duplex connector, serving environments where SC-terminated fiber cabling is the established plant standard. This converter is functionally identical to the LC-variant (AT-DMC1000/LC-90) but uses the SC connector format, which remains widely deployed in enterprise data centers, campus networks, and government facilities with legacy fiber terminations. Auto-negotiation on the copper port handles speed and duplex settings automatically, while Auto MDI/MDI-X removes the crossover cable requirement. The Smart MissingLink (SML) feature ensures that a loss of the fiber segment is immediately reflected as a copper link-down event, enabling upstream switches and monitoring systems to detect and alert on the fault without delay. Smart Link Restoration automatically recovers links following power interruptions or transient link failures without requiring manual resets, reducing the administrative burden in unattended remote locations. The converter is fully transparent to IEEE 802.1Q VLAN-tagged frames, ensuring no disruption to VLAN segmentation policies enforced by connected switches. The built-in link test function allows field technicians to quickly verify connectivity on both the copper and fiber ports, reducing troubleshooting time on network fault calls. The unit is country of origin Singapore, supporting its TAA compliance status, and is RoHS compliant for environmental certification requirements.

Frequently Asked Questions

Q: What fiber type and connector does the AT-DMC1000/SC-90 use?

The AT-DMC1000/SC-90 uses a duplex SC connector for 1000Base-SX multimode fiber. It is compatible with OM1 (62.5/125 µm) and OM2 (50/125 µm) multimode fiber at 850 nm wavelength.

Q: What is the maximum fiber distance?

1000Base-SX supports up to 550 meters over 50/125 µm OM2 multimode fiber and up to 275 meters over 62.5/125 µm OM1 fiber at 850 nm.

Q: Is the AT-DMC1000/SC-90 TAA compliant?

Yes. The unit is manufactured in Singapore, which qualifies under the Trade Agreements Act, and it carries the -90 TAA-compliant designation for U.S. federal government procurement.

Q: How does Smart MissingLink benefit network operations?

Smart MissingLink propagates a fiber link failure to the copper port as a link-down event. Connected switches and monitoring systems detect this immediately, enabling rapid fault notification and reduced mean time to repair.

Q: What is the difference between the AT-DMC1000/SC-90 and the AT-DMC1000/LC-90?

Both models perform identical 1000T to 1000SX Gigabit fiber conversion. The sole difference is the fiber connector: AT-DMC1000/SC-90 uses an SC duplex connector, while AT-DMC1000/LC-90 uses an LC duplex connector. Choose based on your installed fiber plant termination type.

Q: Does this converter support VLAN traffic?

Yes. The AT-DMC1000/SC-90 is fully transparent to IEEE 802.1Q VLAN-tagged frames and does not modify or strip VLAN tags.

Q: Where can I order the AT-DMC1000/SC-90?

The AT-DMC1000/SC-90 is available from Creation Networks at creationnetworks.net.
