SM40G-SR

High-Density 40GbE QSFP+ SR Optical Transceiver for Short-Reach Data Centre Links with the SM40G-SR

The SM40G-SR provides 40GBASE-SR multimode connectivity for 40GbE NICs and switch ports, enabling predictable low-latency uplinks in top-of-rack and leaf-spine designs. SM40G-SR supports bandwidth-consolidated architectures where host CPU and GPU clusters depend on consistent fabric performance, aligning with memory-intensive workloads and shared storage backplanes by reducing interconnect bottlenecks over short-reach optical paths.

Why Choose the SM40G-SR?

The SM40G-SR delivers reliable QSFP+ optics for dense 40GbE fabrics, keeping link performance consistent while scaling port count and rack density. SM40G-SR simplifies standardised spares and reduces risk during expansion.

Chelsio engineers SM40G-SR for enterprise data centres with disciplined signal integrity, compatibility, and operational stability, supporting structured cabling practices and modern switching standards in production environments.

Key Applications:

Top-of-rack 40GbE uplinks
Leaf-spine 40GbE interconnects
Legacy 40GbE fabric expansion
HPC cluster interconnect

At Happyware - Server Hardware you benefit from non-binding offers tailored to your deployment of SM40G-SR optics and an extended warranty up to 6 years to protect long-term data centre operations.
