Allied Telesis AT-MMC200/ST-960 – TAA Federal 10/100TX to 100FX ST Media Converter

Overview

The Allied Telesis AT-MMC200/ST-960 is a TAA-compliant media and rate converter that bridges 10/100 Mbps copper Ethernet to 100 Mbps multimode fiber with an ST connector. It supports fiber runs up to 2 km, enabling organizations to extend network connectivity beyond the 100-meter limit of copper UTP. The -960 suffix designates TAA compliance, qualifying this unit for U.S. federal government procurement. This converter handles automatic rate conversion between 10BASE-T, 100BASE-TX, and 100BASE-FX, eliminating the need for matching speeds on both sides of the link.

Description

The AT-MMC200/ST-960 provides a straightforward copper-to-fiber conversion path for organizations extending legacy or cost-sensitive 10/100 Ethernet segments over multimode fiber infrastructure. The ST connector is common in older structured cabling plants and campus fiber runs, making this converter a practical choice for environments where ST fiber is already installed. Auto-negotiation on the copper RJ-45 port allows it to adapt to 10BASE-T or 100BASE-TX devices without manual configuration, while the fiber side operates at fixed 100BASE-FX. The integrated rate conversion function allows a 10 Mbps copper device to communicate across a 100 Mbps fiber link without requiring speed matching at both ends. Maximum fiber reach is 2 km over standard 62.5/125 or 50/125 multimode fiber, covering intra-building and short campus runs. The compact form factor supports desktop deployment or installation in an Allied Telesis media converter chassis for centralized rack management. TAA compliance under the -960 designation satisfies federal acquisition requirements for government IT infrastructure projects. This unit requires no software configuration and is operational immediately upon connection, reducing deployment time and IT overhead.

Key Features

• Copper to multimode fiber conversion: Bridges 10/100BASE-TX RJ-45 copper to 100BASE-FX ST multimode fiber in a single device.
• Automatic rate conversion: Converts between 10 Mbps and 100 Mbps without manual configuration, enabling mismatched-speed segments to interoperate.
• ST fiber connector: Compatible with existing ST-terminated multimode fiber plant common in government and campus buildings.
• Up to 2 km fiber reach: Extends connectivity well beyond the copper UTP 100-meter limit for intra-building and short campus links.
• TAA compliant (-960): Qualifies for U.S. federal procurement under Trade Agreements Act requirements.
• Desktop or chassis-mount form factor: Operates standalone or slides into an Allied Telesis media converter chassis for centralized management.
• Plug-and-play operation: No software or configuration required; operational immediately on power-up.

Typical Applications

• Extending copper LAN segments to remote offices or building wings over existing multimode fiber
• Connecting 10/100 Mbps IP cameras, access control panels, or IoT devices over fiber runs exceeding copper distance limits
• Federal agency and government building network infrastructure requiring TAA-compliant hardware
• Migrating legacy ST-fiber cabling plants to modern switched Ethernet without re-cabling
• Centralized media conversion deployments using Allied Telesis chassis
