Keep access-layer links stable with a 1 GbE SX SFP built for multimode fiber runs up to 500 m. The LC interface and compact SFP form factor make it a practical fit for switch uplinks, distribution closets, and edge aggregation where density and serviceability matter. Designed as an Aruba-compatible transceiver, it supports straightforward replacement planning for teams standardizing on proven 1 Gb optics. This module is a strong choice when you need short-reach fiber without paying for longer-distance optics you will not use. It is well suited to campus backbones, building-to-building links within the same site, and high-density switching environments that benefit from hot-pluggable optics. For infrastructure teams, the value is in predictable reach, simple installation, and a familiar LC/MMF design that keeps procurement and spares management clean.
