Juniper EX-SFP-1FE-LX SFP 1310 nm 10 km | Single-Mode, LC

Keep Fast Ethernet uplinks stable over distances that exceed copper limits. Juniper EX-SFP-1FE-LX is built for single-mode fiber deployments that need dependable 100BASE-LX connectivity across campus links, remote closets, and inter-building runs. Its 1310 nm optics and LC interface support clean integration into existing fiber infrastructure while preserving signal integrity over longer spans. This module fits environments where link reliability matters more than commodity pricing. Single-mode fiber gives you the reach and margin needed for structured cabling, and the 10 km operating distance helps reduce design constraints in distributed networks. For teams standardizing on Juniper optics, this transceiver supports consistent deployment behavior and simplifies spares planning across access and aggregation layers. Choose this module when you need a compact, hot-swappable fiber component that extends Fast Ethernet without redesigning the network. It is a practical fit for legacy 1 GbE edge connections, building interconnects, and fiber handoffs where predictable performance and vendor-aligned compatibility matter.
