Keep long-haul fiber links stable with a TAA-compliant 1000BASE-EX SFP transceiver designed for Avaya/Nortel environments. This AddOn Networks module supports 1 GbE over single-mode fiber, making it a practical fit for campus backbones, building-to-building interconnects, and other deployments where copper falls short. The 1000BASE-EX standard is built for distance, and this transceiver is specified for 1310 nm operation with a reach of up to 40 km. That gives infrastructure teams room to connect remote closets, aggregation points, and distributed sites without introducing extra conversion layers. The compact SFP form factor keeps deployment simple in supported switches and routers, while the TAA-compliant designation helps satisfy procurement requirements for public sector and regulated environments. For teams standardizing on compatible optics, this module offers a straightforward path to extend existing hardware without overbuying capacity. It is a focused, purpose-built transceiver for networks that need reliable long-distance Ethernet transport at 1 GbE speeds.
