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

The EX-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: EX-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.

Host-programmed and qualified against Juniper platforms, it slots in beside existing OEM and third-party optics, reports clean DDM telemetry, and needs no special configuration to bring the link up.

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.
