Keep high-speed links alive across distance without adding complexity. This HPE Aruba 10 GbE SFP+ transceiver uses bidirectional LC optics to carry traffic over single-mode fiber with a 40 km reach, making it a strong fit for inter-building runs, remote closets, and distributed campus designs. The 1,270/1,330 nm wavelength pair reduces fiber requirements by sending and receiving over a single strand, which can simplify plant design and lower deployment cost compared with paired transceivers. For teams standardizing on Aruba switching, it delivers the optical reach and interface consistency needed to support stable uplinks between aggregation points, edge sites, and core infrastructure. This module is built for environments where link distance, port density, and predictable interoperability matter more than commodity pricing. It is the right choice when a short-reach optic would force extra infrastructure, or when a duplex design would consume more fiber than the site can spare. Use it to preserve bandwidth over long runs while keeping the network architecture clean and manageable.
