Juniper SRX-SFP-1GE-SX 1000Base-SX SFP Module | Gigabit Ethernet

Extend SRX networking with a compact optical module built for short-reach Gigabit Ethernet links. The SRX-SFP-1GE-SX delivers 1000Base-SX connectivity over multimode fiber, giving infrastructure teams a straightforward way to add fiber uplinks without changing the platform footprint. This module is suited to environments where predictable access-layer performance and clean cable management matter more than excess complexity. With a single 1000Base-SX interface, it supports focused deployments that need a reliable optical path between switches, routers, and adjacent network equipment. It is also aligned to SRX210 base system compatibility, making it a practical fit for Juniper edge deployments that require a known-good transceiver option. For teams standardizing on fiber at the edge, this SFP helps preserve port density while maintaining the signal characteristics expected from multimode short-reach links. It is a precise choice for organizations that want to keep their network design simple, serviceable, and consistent across branch or campus infrastructure.
