EX-SFP-1GE-SX-ET is the Juniper 1000BASE-SX extended-temperature SFP order. Its defining procurement facts are 1 Gbps, dual-fiber MMF, 850 nm and up to 550 m by fiber grade; connector shape alone does not make another SFP equivalent.
Verify the installed multimode grade and modal-distance limit, then retain ambient range and received-power readings at the actual equipment location.
Confirm the exact Juniper chassis, interface module and Junos release in Hardware Compatibility Tool before purchase. At installation, clean applicable optical connectors, verify polarity or BiDi pairing, record DOM levels when supported, inspect errors and preserve the tested port configuration.
