OEM QSFP Active Optical Cables (AOCs) provide high-speed, long-reach connectivity for data centers and networking applications, supporting data rates from 10G up to 400G.Overview

Active Optical Cables (AOCs) in QSFP form factors are high-performance optical interconnects designed to replace traditional copper cables for medium- to long-reach connections. They integrate optical transceivers and fiber into a single assembly, offering low power consumption, high bandwidth, and improved signal integrity compared to passive copper solutions . OEM AOCs are manufactured to meet original equipment manufacturer specifications, ensuring compatibility with major switch and server vendors such as Cisco, Juniper, Arista, Dell, HP, and Brocade .

Data Rates and Standards

QSFP AOCs support a wide range of data rates:

  • 10G, 25G, 40G, 50G, 56G, 100G, 200G, and 400G depending on the cable and transceiver type .
  • Compliant with QSFP MSA, QSFP-DD, OSFP, IEEE 802.3 standards, and SFF-8436 for interoperability .
  • Available in multiple variants such as SR4, eSR4, IR4, LR4, ER4 lite, and breakout AOCs for flexible deployment .
Applications

QSFP AOCs are widely used in:

  • Data centers for high-speed server-to-switch and switch-to-switch connections.
  • High-performance computing (HPC) clusters requiring low-latency, high-bandwidth interconnects.
  • Campus and metropolitan area networks where long-reach optical links are needed .
Advantages
  • Longer reach and flexibility compared to passive copper cables.
  • Lower power consumption and reduced heat generation.
  • Plug-and-play compatibility with multiple OEM switches and servers.
  • Compact form factor suitable for dense networking environments .
OEM and Testing

Reputable OEM suppliers, such as OEM Optic, USource, Amphenol, TE Connectivity, and FS.COM, provide AOCs that are tested for compatibility and performance in real-world network environments. These tests ensure that each module meets OEM specifications and operates reliably across different platforms . Many suppliers also offer custom programming and quality control to guarantee interoperability with major networking equipment .

Conclusion

OEM QSFP Active Optical Devices are essential for modern high-speed networks, offering scalable, reliable, and energy-efficient optical connectivity. They are ideal for data centers, HPC clusters, and enterprise networks requiring high bandwidth, low latency, and long-reach optical links. Selecting OEM-certified AOCs ensures compatibility, performance, and longevity in demanding network environments.
