Huawei 40G QSFP+ Module for High-Speed Short-Reach Networking

The Huawei 40G QSFP+ module delivers high-speed performance for short-range fiber networks. It supports 40GBASE-SR4 applications and operates at an 850nm wavelength over multimode fiber (MMF).

Built for 40GBASE-SR4 Performance

This QSFP+ module meets IEEE 802.3ba standards and enables fast, stable 40 Gbps connections. It reaches up to 150 meters on OM4 fiber, 100 meters on OM3, and 30 meters on OM2. These capabilities make it ideal for intra-data center links and high-bandwidth short-haul applications.

The module uses VCSEL (Vertical-Cavity Surface-Emitting Laser) transmitters. You’ll also find MPO/MTP connectors, which simplify high-density cabling and ensure easy deployment in server rooms.

Flexible and Reliable Optical Specifications

Optical power values vary by model, but you can expect a maximum average transmit power of up to 5 dBm. Minimum transmit power may range from -7.6 dBm to -4 dBm. Extinction ratios vary from 3.0 dB to 4.5 dB, supporting stable signal output.

Receiver sensitivity typically reaches -9.5 dBm, allowing consistent performance even under low optical power conditions. These ranges meet the demands of modern high-performance networks.

Designed for Modern Data Centers

This module integrates seamlessly into Huawei and compatible equipment. Its short-reach capability and MPO connector make it perfect for rack-to-rack connections, reducing latency and increasing throughput.

Whether you’re upgrading core switches or expanding your data center, this transceiver supports fast deployment with high port density and minimal footprint.

Conclusion:
The Huawei 40G QSFP+ module offers reliable, high-speed transmission over short distances. Use it to enhance your data center’s 40G networking performance while ensuring compliance and efficiency.
