In high-density hyperscale data centers, the QSFP-4X10G-AOC3M=-3M 40GBASE Active Optical QSFP to 4SFP Breakout Cable consolidates four 10GbE SFP+ server connections onto a single 40GbE QSFP port. This streamlined cabling reduces switch port exhaustion, lowers operational costs by up to 30%, and accelerates deployment with plug-and-play simplicity.
For HPC environments requiring ultra-low latency and high bandwidth, the QSFP-4X10G-AOC3M=-3M cable links four compute nodes at 10GbE each into a 40GbE backbone. The result is a unified, lossless fabric that delivers up to 40 Gbps aggregate throughput, optimizes parallel workloads, and minimizes latency by leveraging active-optical signal integrity over 3 meters.
Cloud and managed-service providers use the QSFP-4X10G-AOC3M=-3M cable to break out a 40GbE uplink into four independent 10GbE tenant ports at the network edge. This approach maximizes rack space efficiency, ensures secure traffic isolation, and speeds up tenant provisioning—delivering service-level guarantees with minimal capital and power expenditure.

3m active optical splitter cable provides stable 10G connectivity. Ideal for breakout deployments.
Easy deployment with consistent throughput and low latency.
Durable cable suitable for high-density data centers.
Maintains reliable performance under full load. Professional-grade quality.
Smooth installation and consistent output across all SFP+ ports.
The QSFP-4X10G-AOC3M= is a 3-meter, 40GBASE-active optical cable that breaks out one QSFP+ port into four 10G SFP+ interfaces.
An AOC uses fiber optics and integrated transceivers to achieve longer reach and lower weight compared to copper direct attach cables (DACs).
This cable supports 40GBASE-SR4 on the QSFP+ side and 10GBASE-SR on each SFP+ breakout strand, compliant with IEEE 802.3ba and IEEE 802.3aq.
At 50 µm multimode fiber, it supports up to 3 meters; other distances require corresponding AOC SKUs.
Yes. The QSFP-4X10G-AOC3M= breaks out a single 40G QSFP+ interface into four independent 10G SFP+ links.
Yes. It supports hot-swapping in compliant QSFP+ and SFP+ slots without disrupting operation.
Yes. It offers full DDM/DOM functionality for real-time monitoring of optical power, temperature, and voltage.
It is interoperable with QSFP+- and SFP+-compliant switches, routers, and optics from major vendors when set to 40GBASE-SR4 and 10GBASE-SR modes.
Typical power consumption is under 1 W per breakout cable, meeting standard QSFP+ power budgets.
It operates reliably between 0 °C and 70 °C (32 °F to 158 °F) ambient temperature.
Simply plug the QSFP+ connector into the 40G port and each SFP+ connector into the 10G ports—no additional configuration is required.
Yes. It is tested for interoperability across leading switch and router brands when ports are set to the correct base standards.
