Build longer fiber runs without moving to a larger optics class. This 1 GbE LX SFP is designed for single-mode fiber links up to 10 km, giving infrastructure teams a compact option for campus backbones, inter-building connections, and extended access uplinks. The LC interface keeps cabling standardized, while the SFP form factor supports fast replacement and clean inventory management. For environments where short-reach optics are not enough, this module provides the distance headroom needed to connect distributed network spaces without adding complexity. It is a practical fit for teams that want to preserve switch density, keep spare parts aligned to a known MPN, and maintain compatibility with Aruba-oriented deployments. The result is a disciplined fiber option that matches the cost of the link to the distance it must cover.
