EX-SFP-1GE-SX-ET — 1000Base-SX Extended Temperature Optics

The Juniper EX-SFP-1GE-SX-ET is a 1000Base-SX Gigabit Ethernet SFP transceiver over multi-mode fiber (MMF) featuring an extended operating temperature range of -40 to 85 °C. With a reach of 550 m via Duplex LC connector, this Extended Temperature (ET) version differs from the standard EX-SFP-1GE-SX by its ability to operate in thermally constrained environments such as outdoor enclosures or industrial sites. Data rate: 1 Gbps.

This reference is designed for harsh-environment deployments — unconditioned telecom cabinets, industrial or outdoor settings — where commercial-grade modules are insufficient. The EX-SFP-1GE-SX-ET delivers full reliability across the most demanding temperature ranges. Genuine Juniper hardware, manufacturer warranty.
