Keep critical fiber links online with a TAA-compliant 1000BASE-LX SFP built for HP JD119B compatibility. This AddOn Networks transceiver is designed for single-mode fiber deployments that need dependable Gigabit Ethernet transport across longer distances than short-reach optics can support. The 1310 nm wavelength and LC connector align with common enterprise fiber infrastructure, making it a practical fit for access switches, aggregation layers, and inter-building runs. For infrastructure teams, the value is in consistency: a standards-based LX optic that slots into existing SFP ports without forcing a platform change. It supports the kind of long-haul, point-to-point connectivity that keeps remote closets, campus buildings, and distribution points tied into the core. TAA compliance also makes it suitable for procurement environments with sourcing requirements that exclude non-compliant alternatives. Choose this module when you need a cost-conscious replacement or expansion optic that still meets enterprise expectations for reach, interoperability, and procurement control. It delivers the right balance of compatibility and distance for networks where downtime, re-cabling, or vendor lock-in are not acceptable.
