Keep critical network segments connected across longer distances with the Axiom AT-SPEX-AX 1000BASE-LX SFP transceiver. Designed for Allied Telesis environments, this MSA-compliant module supports Gigabit Ethernet over multimode fiber and uses an LC duplex connector for straightforward deployment in optical networking infrastructure. With support for up to 10 km, it fits access, aggregation, and campus links where copper falls short and budget optics are not enough. The LX design gives you the reach needed for distributed closets, building-to-building runs, and backbone extensions without changing the switching platform. That makes it a practical choice for teams standardizing on proven transceiver form factors while preserving compatibility and serviceability. Axiom backs the module with a lifetime limited warranty, adding long-term confidence for procurement teams that want predictable lifecycle support. If you need a replacement or expansion optic that aligns with Allied Telesis hardware and keeps Gigabit links stable over distance, this module delivers the right balance of reach, compatibility, and value.
