Allied Telesis AT-MMC2000/SC-960 – Gigabit Media Converter SC Multimode TAA

Product Overview

The Allied Telesis AT-MMC2000/SC-960 is an Allied Telesis Gigabit media converter SC multimode TAA Federal model that converts 10/100/1000Base-T copper (RJ-45) to 1000Base-SX multimode fiber (SC connector) with rate conversion support. TAA compliant for U.S. federal and government procurement, the MMC2000/SC-960 serves enterprise network fiber extension, campus backbone fiber interconnects, and government facility network upgrades requiring compliant hardware. The MMC series is engineered for minimal power consumption — just 1.7W — and a small footprint, making it one of the most efficient Gigabit media converters available for high-density or energy-conscious deployments.

Product Description

The Allied Telesis MMC2000/SC-960 is a mini media and rate converter that bridges 10/100/1000Base-T Gigabit Ethernet copper to 1000Base-SX multimode fiber via an SC connector, handling both media conversion and rate conversion in a single device. Rate conversion capability means the copper port auto-negotiates at 10, 100, or 1000 Mbps while the fiber side operates at 1000Base-SX — enabling legacy 10/100 copper endpoints to connect into a Gigabit fiber backbone without switch upgrades. The MMC series is designed with a minimal carbon footprint in mind, consuming only approximately 1.7W, which is among the lowest power draws of any Gigabit media converter in the market. Multimode fiber is supported at 850 nm over 50/125 µm and 62.5/125 µm cable with a maximum distance of 500 meters (1,640 feet), covering the majority of in-building and campus fiber runs. A 2K MAC address table and store-and-forward switching mode ensure correct frame handling for all Ethernet traffic types. The Smart MissingLink feature monitors both network segments and notifies the network management system of segment failures, enabling faster root-cause identification. Smart Link Restoration automatically restores connectivity following power loss or link interruption without requiring a device reset, which is essential for unattended remote installations. The converter is transparent to IEEE 802.1Q VLAN-tagged jumbo frames up to 10KB, compatible with all modern enterprise switching platforms. Far End Fault detection on the fiber port and per-port Link/Activity LEDs provide additional operational visibility. The unit is powered by an included external AC adapter and is rack-mountable or wall-mountable for deployment flexibility.

Frequently Asked Questions

Q: What fiber type does the AT-MMC2000/SC-960 support?

The AT-MMC2000/SC-960 supports 1000Base-SX multimode fiber with an SC duplex connector. It is compatible with 50/125 µm (OM2) and 62.5/125 µm (OM1) multimode fiber at 850 nm, with a maximum distance of 500 meters over OM2 fiber.

Q: Is the AT-MMC2000/SC-960 TAA compliant for federal purchasing?

Yes. The -960 suffix designates TAA compliance. The unit is manufactured in Singapore, which qualifies under the Trade Agreements Act for U.S. federal government and GSA schedule procurement.

Q: What does rate conversion mean for this product?

Rate conversion means the copper port auto-negotiates at 10, 100, or 1000 Mbps while the fiber port always operates at 1000 Mbps. This allows legacy 10/100 Mbps copper-connected devices to connect into a Gigabit fiber backbone without requiring a switch upgrade.

Q: How much power does the MMC2000/SC-960 consume?

Approximately 1.7W, which Allied Telesis states represents over 50% power savings compared to standard-size media converters. This makes it suitable for high-density and energy-efficient deployments.

Q: What happens if the network link drops?

Smart MissingLink propagates the failure end-to-end, and Smart Link Restoration automatically re-establishes the link after power or connectivity is restored, without requiring any manual reset or configuration intervention.

Q: Does it support VLAN and jumbo frame traffic?

Yes. The converter is transparent to IEEE 802.1Q VLAN-tagged frames and supports jumbo frames up to 10KB, compatible with all enterprise switching platforms.

Q: Where can I purchase the AT-MMC2000/SC-960?

The AT-MMC2000/SC-960 is available from Creation Networks at creationnetworks.net.
