JNP-100G-ER4 Juniper Compatible 100G QSFP28 ER4 40km SMF Transceiver

The JNP-100G-ER4 is a 100G QSFP28 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: QSFP28
• Data Rate: 100G
• Protocol: ER4
• Wavelength: 1550nm
• Fiber Type: SMF
• Reach: 40km
• Connector: Duplex LC
• OEM Equivalent: JNP-100G-ER4

Extended-reach optics push single-mode links out to metro distances, connecting sites across a city or campus where standard long-reach modules run out of optical budget. It is the right tool when the span is too far for an LR but does not yet justify coherent line-side gear. It operates 40km in the 1550nm window.

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.

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.
