The Mellanox MC2210411-SR4 40GBASE-SR Optical Module 

The Mellanox MC2210411-SR4 1 x 40GBASE-SR QSFP optical transceiver module represents a high-performance networking component engineered for modern data center environments requiring ultra-fast, low-latency, and energy-efficient fiber connectivity. Designed for 40 Gigabit Ethernet (40GbE) applications, this QSFP+ SR4 module supports short-range multimode fiber transmission and is widely deployed in high-density switching, enterprise aggregation layers, and cloud-scale networking architectures. As part of the advanced optical networking ecosystem developed under Technologies), this module plays a critical role in enabling scalable and efficient data movement across high-speed infrastructures.

40G Optical Networking

The MC2210411-SR4 module is positioned within the 40GBASE-SR4 optical transceiver category, optimized specifically for short-reach multimode fiber (MMF) connections. It is engineered to deliver reliable 40Gb/s aggregate bandwidth using four parallel lanes, each transmitting at 10Gb/s over multimode fiber pairs. This parallel optics approach ensures efficient data transmission with reduced signal distortion and improved throughput stability across supported network architectures.

In modern networking deployments, especially in hyperscale data centers, the demand for high-bandwidth, low-latency communication has grown significantly. The Mellanox SR4 QSFP module is designed to meet these requirements by supporting high-density switch interconnects, leaf-spine architectures, and aggregation uplinks between core and edge network layers.

QSFP+ Form Factor and Interface Design

The QSFP+ (Quad Small Form-Factor Pluggable Plus) interface used in the MC2210411-SR4 module is a compact, hot-pluggable design that integrates four independent transmit and receive channels into a single module. This architecture significantly reduces port density requirements while maximizing throughput per rack unit, making it ideal for environments where space optimization and scalability are critical.

The module interfaces directly with compatible QSFP+ ports on switches, routers, and network interface cards, allowing seamless integration into existing 40G Ethernet infrastructures without the need for extensive hardware redesign.

40GBASE-SR4 Transmission Technology

The 40GBASE-SR4 standard is based on IEEE 802.3ba specifications and utilizes short-reach multimode fiber optics operating at an 850nm wavelength. The MC2210411-SR4 module transmits data over four parallel lanes, each operating at 10Gb/s, resulting in a total aggregated bandwidth of 40Gb/s.

This parallel transmission method ensures high throughput efficiency while maintaining signal integrity across short-distance fiber runs. The SR4 standard typically supports link distances up to 100 meters using OM3 fiber and up to 150 meters using OM4 fiber, depending on cabling quality and installation conditions.

850nm VCSEL Laser Technology

The module employs Vertical-Cavity Surface-Emitting Laser (VCSEL) technology operating at an 850nm wavelength. VCSEL-based optical transmission is widely used in short-reach data center networking due to its low power consumption, cost efficiency, and high modulation speed.

The integration of VCSEL arrays ensures consistent signal output across all four channels, reducing latency and improving synchronization between parallel data lanes. This makes the module highly suitable for high-performance computing clusters and distributed storage networks.

High-Speed Data Center Connectivity

The MC2210411-SR4 module is primarily designed for high-speed interconnects within data centers. It enables seamless communication between top-of-rack (ToR) switches, aggregation switches, and spine-layer switching fabrics. Its 40G bandwidth capability supports large-scale virtualized environments where rapid data transfer between servers and storage nodes is essential.

In cloud computing infrastructures, this module enhances east-west traffic performance, reducing bottlenecks and ensuring consistent application delivery across distributed systems.

Enterprise Network Scaling

Enterprise environments increasingly rely on scalable network infrastructures to support cloud integration, big data analytics, and real-time application processing. The MC2210411-SR4 QSFP module provides a cost-effective upgrade path from 10G Ethernet to 40G Ethernet, enabling enterprises to expand network capacity without replacing entire switching infrastructures.

Its compatibility with existing multimode fiber cabling further reduces deployment costs and simplifies network migration strategies.
