Allied Telesis AT-SPSX/SC – TAA 1000BASE-SX SFP with SC Connector

Overview

The Allied Telesis AT-SPSX/SC is a TAA-compliant 1000BASE-SX SFP transceiver that uses an SC duplex connector instead of the more common LC interface, making it a direct fit for legacy fiber infrastructure wired with SC patch cords and panels. It operates at 850nm over multimode fiber with reach of 220 meters on 62.5µm fiber and 550 meters on 50µm fiber. TAA compliance supports procurement under U.S. federal contracts and GSA schedules. The hot-swappable SFP form factor allows field replacement without host switch downtime.

Description

Many installed multimode fiber networks, particularly those deployed in the late 1990s and early 2000s, use SC connectors throughout their fiber plant. Replacing all SC-terminated cables and panels to accommodate LC-only SFPs introduces unnecessary cost and disruption. The AT-SPSX/SC resolves that by providing a standard 1000BASE-SX optical interface in an SFP shell with an SC duplex connector, allowing direct connection to SC-terminated fiber without adapters. The 850nm wavelength is compatible with standard OM1 and OM2 multimode fiber, supporting distances up to 220m and 550m respectively. Performance is equivalent to LC-based 1000BASE-SX SFPs; only the fiber connector interface differs. TAA compliance satisfies federal and government procurement requirements without exceptions or waivers. Hot-swap support means technicians can install or swap the transceiver on a live switch, reducing impact on connected users. The standard SFP form factor ensures compatibility with Allied Telesis switches and any MSA-compliant equipment that provides SFP slots. Available from Creation Networks for enterprise and federal buyers maintaining SC-based fiber plants.

Key Features

• SC Duplex Connector: Designed for legacy multimode fiber plants terminated with SC connectors, eliminating the need for LC adapters or re-termination.
• TAA Compliant: Meets Trade Agreements Act requirements for federal, state, and GSA-schedule procurement.
• 1000BASE-SX, 850nm: Full Gigabit Ethernet performance over standard OM1 and OM2 multimode fiber at industry-standard wavelength.
• 220m / 550m Reach: Covers intra-building links on 62.5µm and 50µm fiber respectively without additional repeaters.
• Hot-Swappable: Field-replaceable without powering down the host switch, supporting live network maintenance.
• Standard SFP Form Factor: Compatible with Allied Telesis and third-party MSA-compliant switches and routers.
