With the advent of the big-data age, the cloud technology has developed rapidly. In order to satisfy the demands of higher bandwidth and more applications in a variety of cloud computing environments, active optical cable (AOC) has emerged. Nowadays, the market of AOCs keeps growing and has a broad prospect. Today, Fiberstore blog will introduce the AOCs and discuss its prospect forecast.
What’s Active Optical Cable (AOC)?
Active Optical Cable (AOC) is used for short-range multi-lane data communication and interconnect applications. In fact, the wire transmission of optical communication should belong to passive part, however, AOC is special. AOC integrates multimode optical fiber, fiber optic transceivers, control chip and modules. It uses electrical-to-optical conversion on the cable ends to improve speed and distance performance of the cable without sacrificing compatibility with standard electrical interfaces. As people expect more information to be available at their fingertips, our communications systems will need to be quicker, and AOC is one of the best solutions to this challenge. Compared with common cable for data transmission, AOC provides more advantages, such as lighter weight, high performance, low power consumption, low interconnection loss, EMI immunity and flexibility. With its benefits, AOC is widely used in many fields as well as promoting the traditional data center to step into optical interconnection. Now, market of AOCs is booming.
Development of AOCs
Primarily, active optical cable (AOC) assemblies were invented to replace copper technology in data centers and high performance computing (HPC) applications. As we know, copper cable is heavy and bulky, making it difficult to physically manage the datacenter. And due to the nature of electrical signals, electromagnetic interference (EMI) limits copper’s performance and reliability. Though there are so many disadvantages of copper cable, at that time, it is the main stream while the idea of AOCs almost seems too good to be true. However, the advantages of AOC make the predecessors look obsolete and unsophisticated, and changes the limitation of copper cable as well as playing an important role in high speed data transmission. Nowadays, a variety of AOCs have been launched in the market, such as 10GbE SFP+ AOCs, 40Gbps QSFP+ AOCs and 120G CXP AOCs, for 10G, 40G and 100G applications.
Comparison of Passive, Active, Copper and Fiber
Passive cabling provides a direct electrical connection between corresponding cable ends. Active cables provide the same effect but, by embedding optics and/or electronics within the connectors, can overcome some of the limitations of passive cables. While passive cables are always copper-based, active cables can use either copper wire or fiber optics to provide the link between the cable ends. About the difference between copper and fiber, we have talked above. The following picture shows us the leading types of passive and active cables for data center.
Prospect of AOCs
AOCs market has continued to grow and attract new entrants, including some of the world’s biggest suppliers of cabling and telecom components. The market and application prospect of AOCs will have a broader development.
According to the newest report, sales of active optical cables (AOCs) for the data center will produce $1.5 billion in revenues by 2019. The application fields of AOCs are mainly in data center and have a large proportion. Additionally, in HPC, consumer electronics, HDMI and digital signage, AOCs are also increasing in application. The application of active optical cables (AOC) in future data center will focus on high speed transmission, such as 40Gbps, 100Gbps and even InfiniBand.
The following diagram shows the worldwide AOC market forecast by MSA, from 2014-2020. AOC market keeps growing and developing.
