Build longer-reach 10 GbE links with this AddOn 10GBASE-ER SFP+ transceiver. Designed as a compatible replacement for Avaya/Nortel AA1403013-E6, it supports single-mode fiber transport with 1550 nm optics and an LC duplex connector. That combination is well suited to campus interconnects, storage links, and backbone runs where multimode optics are not enough. TAA compliance makes it easier to specify in public sector and regulated environments, while the SFP+ footprint keeps port density high in switches and routers. For teams maintaining established fiber infrastructure, this module offers a direct path to extend reach without redesigning the network layer. It is a practical choice when the requirement is not just 10 GbE speed, but dependable distance and procurement alignment in the same part.
