40GBASE-IR4 QSFP+ Transceiver

The Axiom JNP-QSFP-4X10GE-IR-AX is a QSFP+ form-factor transceiver built for 40 Gigabit Ethernet links. It targets network engineers who need a standards-compliant module for single-mode fibre runs in Juniper equipment.

MPO Connector and MSA Compliance

The module uses an MPO connector and adheres to the QSFP+ MSA SFF-8436 specification, allowing it to slot into any compliant switch or router port. IEEE 802.3ba compliance ensures interoperability across multi-vendor 40GBASE-IR4 deployments without proprietary lock-in.

2 km Reach on Single-Mode Fibre

Operating at a 1310nm wavelength, the transceiver delivers a maximum reach of 2 km over single-mode optical fibre. This headroom suits campus and metro links, while the 40G data rate caps throughput for workloads that demand 100G or higher lane speeds.

Questions about this item

Does the 40GBASE-IR4 link stay within the 2km single-mode limit under continuous load?

The module is rated for 2km over single-mode fibre at 1310nm, so the distance ceiling is the first boundary you hit in sustained operation.

What is the typical heat output when the QSFP+ transceiver runs all day?

The part complies with QSFP+ MSA SFF-8436 and IEEE 802.3ba, which define the thermal envelope for continuous 40G operation.

Which switch or router port must I already have to plug this MPO transceiver in?

You need a QSFP+ port that supports 40GBASE-IR4 and accepts MPO single-mode connectors.
