Allied Telesis AT-SPLX40 – 1000BASE-EX SFP 40km Single-Mode LC Transceiver

Overview

The Allied Telesis AT-SPLX40 is a hot-swappable SFP transceiver supporting 1000BASE-EX operation over single-mode dual fiber with an LC connector interface. It is rated for transmission distances up to 40km at 1310nm, making it appropriate for long-haul Gigabit Ethernet access and distribution links. The standard (non-TAA) variant is compatible with Allied Telesis switches and routers that accept industry-standard SFP modules. The AT-SPLX40 provides a cost-effective path for extending GbE connectivity across campus, metropolitan, and wide-area fiber spans.

Description

The AT-SPLX40 SFP module is designed for network engineers who need to extend Gigabit Ethernet links beyond the reach of standard 1000BASE-LX transceivers, reaching up to 40km over single-mode dual fiber without inline optical amplification. Operating at 1310nm, it uses established single-mode fiber infrastructure commonly deployed in campus backbone and metropolitan fiber ring topologies. The LC duplex connector interface is the industry standard for SFP fiber transceivers, ensuring compatibility with existing patch panels and fiber termination hardware. Hot-swap capability allows the module to be installed and removed from an active chassis without powering down or disrupting other ports, which is important during maintenance windows in live network environments. This is the standard variant, not TAA-compliant; for U.S. federal procurement requirements, the TAA variant should be specified instead. The AT-SPLX40 is validated for use with Allied Telesis switches and routers that provide SFP slots, and follows MSA (Multi-Source Agreement) physical dimensions for broad platform compatibility.

Key Features

• 40km Single-Mode Reach: Extends GbE links up to 40km over standard single-mode fiber without optical repeaters, covering campus and metro-scale distances.
• 1000BASE-EX Standard: Conforms to established GbE extended-range optics specifications for predictable interoperability on qualified platforms.
• 1310nm Wavelength: Operates on the widely deployed 1310nm single-mode fiber window, compatible with existing infrastructure.
• LC Duplex Connector: Industry-standard LC interface aligns with common patch panel and fiber distribution hardware.
• Hot-Swappable: Field replacement and installation without chassis power-down reduces maintenance complexity and downtime risk.
• SFP MSA Form Factor: Standard SFP dimensions ensure physical compatibility across Allied Telesis platforms with SFP slots.
