Module overview

Hot-pluggable QSFP+ MSA form factor
DDM digital diagnostics for TX/RX monitoring
3-year warranty · free technical support
Coding confirmed against your switch model

The 40GBASE-IR4 QSFP+ transceiver delivers 40 Gbps over single-mode fiber (SMF) using 1310 nm with a duplex LC connector, up to 2 km. It is hot-pluggable, QSFP+ MSA-compliant, and supports DDM digital diagnostics.

Typical deployments

40G QSFP+ remains a cost-effective aggregation layer: ToR-to-spine uplinks, 40G server adapters and legacy 40G switch ports. SR4 and eSR4 use MPO ribbon fiber at 100–300 m; IR4, LR4 and ER4 use LC duplex single-mode up to 40 km.

Before you order

Confirm your switch port is rated for 40G and uses the same 40GBASE-IR4 interface before installing. Share the switch model to confirm coding; every module ships with a 3-year warranty and free technical support.
