Extend single-mode fiber runs with a compact SFP transceiver designed for 1000BASE-LX deployments. This AddOn Networks module is suited to enterprise networks that need dependable long-reach connectivity between switches, aggregation points, and remote closets without moving to a larger optics platform. Operating at 1310 nm, it is aligned with standard single-mode infrastructure and is a practical fit for backbone links where distance and signal integrity are more important than port cost alone. The SFP form factor keeps inventory and replacement planning simple, while the TAA-compliant positioning supports procurement requirements in regulated or contract-driven environments. For teams maintaining mixed vendor environments, this module offers a clean way to standardize on a known optical class while preserving compatibility with existing SFP cages. It is a strong choice when the network design calls for a compact transceiver that can support enterprise fiber runs with disciplined specifications and predictable deployment behavior.
