Direct Attach Active Optical Cables for High Speed Interconnect Solution

Today’s enterprise data centers and networking environments are undergoing an infrastructure transformation, requiring higher speeds, greater scalability, and higher levels of performance and reliability to better meet the demands of business. As speed and performance demands increase, the AOC assemblies have become an integral part of the overall system design. However, AOC design margins and parameters vary widely, and can be the difference between an optimized, highly reliable fabric and the incompatibility issues that drive up support costs. There are various types of AOC assemblies for 10G, 40G, and 100G applications on the market. Judging from the cost performance.

What is the Ideal High-Speed Interconnect Solution?

The ideal high-speed interconnect solution should have such features as optimized for short distances, low cost, low power consumption, small cable bend radius, low cable weight, high density, and low link latency. The only one solution which can meet all the requirements is the direct attach active optical cables.

Direct attach active optical cables, or active optical cables for short, are direct-attach fiber assemblies with optical transceiver (SFP+, XFP, QSFP+, CXP etc.) connectors. They are suitable for short distances and offer a cost-effective way to connect within racks and across adjacent racks. Nowadays the Active Optical Cable (AOC) is accelerating data connectivity for storage, networking, and HPC applications. It leverages fiber optic technology for the transmission of data while reducing the weight, density and power consumption of traditional copper solutions.

Advantages of Active Optical Cables

The AOC assemblies provide the lowest total cost solution for data centers by having the key advantages as following:

  • Low weight for high port count architectures;
  • Small bend radius for easy installations;
  • Low power consumption enabling a greener environment.

Advantages of Direct Attach Copper Cable

Enough data rate for various applications—Today’s direct attach copper cable can support higher data rates than traditional copper interfaces—from 4Gbps to 10Gbps per channel.

Interchangeability—as the developments of copper cable technology, direct attach copper cable is interchangeable and hot swappable with fiber optic modules.

Cost effective—supporting such multiple protocols as Gigabit & 10G Ethernet, 8G FC, FCoE and InfiniBand, direct attach copper cable is a cost effective solution over optical transceivers.
