SRX-QSFP-40G-SR4 Juniper Compatible 40G SR4 150m MMF Transceiver

The SRX-QSFP-40G-SR4 is a 40G QSFP 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: QSFP
• Data Rate: 40G
• Protocol: SR4
• Fiber Type: MMF
• Reach: 150m
• Connector: Duplex LC
• OEM Equivalent: SRX-QSFP-40G-SR4

Short-reach multimode optics like this one live inside the data center — server-to-leaf, leaf-to-spine, and in-row links over OM3 and OM4 fiber where cost-per-port matters more than distance. It is the high-volume workhorse of east-west fabric, keeping optics cost and power low across thousands of ports in a modern build. It operates 150m.

Because it is coded to the Juniper host platform, the switch or router reads it as a factory module — clean in diagnostics, free to mix with OEM and other compatible optics in the same chassis, and needing no firmware exceptions.

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.
