Move 10 GbE farther with an optical module designed for long-reach single-mode links. HPE S2P31A uses an LC connector and supports up to 10 km over SMF, giving infrastructure teams a clean way to connect switches across buildings, floors, or campus segments. This is the right class of transceiver when copper no longer fits the distance or signal integrity requirements. The LR profile keeps the deployment focused on dependable long-haul connectivity while preserving the SFP+ footprint that works across many enterprise switching platforms. For architects planning fiber-based uplinks, the value is in reach and consistency. A 10 km LR optic helps standardize long-distance 10 GbE without moving to a different port architecture. That makes it easier to align procurement, spares, and operational support around a familiar module type while meeting the demands of distributed networks.
