Juniper SFP-1FE-LX-IT 100M LX I-TEMP Transceiver | SFP, Enterprise

Keep legacy Fast Ethernet links online with an SFP transceiver designed for controlled, temperature-variable deployments. The Juniper SFP-1FE-LX-IT delivers 100 MbE LX optical connectivity in a compact SFP form factor, making it a practical fit for access switches and edge network gear that still depend on fiber uplinks. This module is built for environments where equipment rooms, closets, and remote sites can see wider temperature swings than standard office deployments. That matters when you need predictable link behavior without moving to a larger optics platform or replacing working infrastructure. The LX optical design and 1,310 nm wavelength support short-reach fiber runs commonly used for building interconnects and access-layer extensions. For teams maintaining mixed-generation networks, this transceiver helps preserve installed fiber investments while keeping the optics layer simple. It is a focused component, not a feature-heavy one: exactly the kind of part procurement teams specify when they need compatibility, consistency, and a clean path to keep service running.
