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

The SFP-1GE-SX is a 1G SFP optical transceiver engineered as a drop-in equivalent for Juniper platforms,, recognized by the host as a genuine module and ready to pass traffic the moment it seats with no CLI changes.

• Form Factor: SFP
• Data Rate: 1G
• Protocol: SR
• Fiber Type: MMF
• Reach: 550m
• Connector: Duplex LC
• OEM Equivalent: 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.

It is programmed to present native host values, so it interoperates link-to-link with OEM modules on the far end and coexists with installed optics in the same line card without compatibility flags.

We program each module to the Juniper host EEPROM and run it through traffic, DOM, and optical-cleanliness checks before it ships. Class 1 laser certified and RoHS compliant.
