  • High-density 40G throughput delivered over four 11.2Gbps CWDM lanes
  • Hot-pluggable QSFP+ design enables quick deployment without downtime

ALSEYE 40GBASE-IR4 QSFP+ module

The ALSEYE 40GBASE-IR4 QSFP+ optical transceiver module delivers 40 Gbps connectivity over single-mode fibre. It uses a 4-channel CWDM design operating at 1310 nm to reach distances up to 2 km. The hot-pluggable QSFP+ form factor fits compatible switches and routers, drawing a maximum of 3.5 W.

Network engineers extending 40G links

This module suits network engineers who need to extend 40 GbE links between switches across campus or metro single-mode fibre. It is not for teams who need multi-mode fibre support, shorter-reach optics, or copper direct-attach cables. Buyers requiring distances beyond 2 km or higher aggregate bandwidth should evaluate other form factors.

2 km reach over single-mode fibre

The defining specification is the 2 km reach over duplex LC single-mode fibre at 1310 nm. The module complies with IEEE 802.3ba and 40GBASE-LR4 standards, with four CWDM lanes each running at 11.2 Gbps. Digital diagnostics monitoring provides real-time optical parameters for link health verification.

Questions about this item

How do I confirm the 40GBASE-IR4 QSFP+ module is operating correctly after installation?

Check the switch management interface for DDM readings showing each of the four CWDM lanes at up to 11.2 Gbps, temperature within 0 to 70 °C, and power draw near 3.5 W.

What comes in the box and what must I source separately?

The transceiver module itself is supplied; you will need to provide compatible duplex LC single-mode fibre patch cables for the 1310 nm link.

Which reach variant should I select for a 2 km single-mode run?

The 40GBASE-IR4 version is rated for 2 km over single-mode fibre, matching the 1310 nm CWDM4 specification.
