JNP-QSFP-4X10GE-LR Juniper Compatible 40G 10km SMF Transceiver

The JNP-QSFP-4X10GE-LR is a 40G QSFP 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: QSFP
• Data Rate: 40G
• Fiber Type: SMF
• Reach: 10km
• Connector: Duplex LC
• OEM Equivalent: JNP-QSFP-4X10GE-LR

At single-mode reach this module bridges the middle ground — access to aggregation, building-to-building campus links, and short data-center interconnect spans that outrun multimode but never need amplification. The single-mode path keeps the signal clean across the full distance over existing OS1 and OS2 plant. It operates 10km.

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.

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.

Backed by the GreenLights4Life® lifetime warranty — buy it once, covered forever. In stock and ships same or next business day.
