SRX-SFP-1GE-SX Juniper Compatible 1G SFP SX 550m MMF Transceiver

The SRX-SFP-1GE-SX is a 1G SFP optical transceiver engineered as a drop-in equivalent for Juniper platforms,, a like-for-like replacement that the host accepts as native, hot-swappable and ready out of the box.

• Form Factor: SFP
• Data Rate: 1G
• Protocol: SX
• Fiber Type: MMF
• Reach: 550m
• Connector: Duplex LC
• OEM Equivalent: SRX-SFP-1GE-SX

As a 1G short-reach module over multimode fiber, it is the classic access-layer optic for in-building uplinks, IDF-to-MDF runs, and edge-switch aggregation where copper distance falls short. It remains a staple in campus and enterprise networks still running gigabit to the closet over installed multimode. It operates 550m.

Coded to the host EEPROM, it comes up as a genuine module: full diagnostic visibility, no compatibility warnings, and side-by-side operation with optics already in the chassis.

Each unit is programmed to match Juniper host values and bench-tested for traffic conformity, DOM-threshold accuracy, and optical cleanliness before it leaves the bench. Class 1 laser certified and RoHS compliant.
