JNP-QSFP-40GE-IR4 — 40GBase-IR4 2km SMF

The JNP-QSFP-40GE-IR4 is a Juniper QSFP+ optical module compliant with the 40GBase-IR4 standard, offering a reach of 2 kilometers over single-mode fiber with a Duplex LC connector. Positioned between the SR variant (100 m) and the LR variant (10 km), its 2 km reach makes it the right choice for inter-building or inter-room links over short existing SMF runs.

This module addresses the needs of multi-building campuses or distributed datacenter sites where distances exceed short-reach fiber but do not justify a long-reach optical budget. The JNP-QSFP-40GE-IR4 is genuine Juniper hardware, manufacturer warranty.
