Juniper SFP-1GE-SX 1 GbE SX SFP 850 nm LC | SFP Module

Build short-reach fiber links with the Juniper SFP-1GE-SX transceiver. This 1000Base-SX Gigabit Ethernet SFP is designed for multimode optical fiber and uses an LC duplex connector to support clean, high-density connectivity in data networking environments. With a 1 Gbps data rate, it fits access uplinks, switch interconnects, and other 1 GbE paths where predictable optical behavior matters. The value of this module is not just the link speed. It is the fit. Juniper lists support across multiple SFP-based platforms, including PE-1G-SFP, P-1GE-SFP, PB-1GE-SFP, PB-2GE-SFP, PB-4GE-SFP, PC-10GE-SFP, and QPP variants, which makes it a practical choice for standardized fleets. The single-port SFP design keeps installation simple, while the United States country of origin and Juniper sourcing help procurement teams align on vendor traceability. For environments that prefer platform-specific optics over lower-cost substitutes, this transceiver supports that decision with clear compatibility and production-grade fiber connectivity.
