Worldwide Active Optical Cable Market Forecast
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, a new type of cable has emerged, such as SFP+ DACs (eg. SFP+ AOC, passive SFP+ cable, active SFP+ cable). 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, said Brad Smith, Senior Vice President and Lead Analyst, LightCounting as, "AOCs are positioned to become ".a disruptive force in telecommunications and datacom transceiver markets in the near future."
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.
Applications of AOCs
In general, AOC assemblies can be used on optical backplanes, rack-to-rack, shelf-to-shelf interconnect, storage, hubs, switches, routers, servers, etc.
- InfiniBand QDR, DDR and SDR interconnects
- Data Aggregation, Backplane and Proprietary Density Applications
- PCI-Express, SAS/SATA, Fiber Channel compatible interconnect

Direct-attach Cable Market Research 2014
Today's enterprise data center networks are undergoing an infrastructure transformation, requiring higher speeds, greater scalability, and higher levels of performance and reliability to better respond to new business requirements. The 10 Gbps Direct Attached cable (1 m, 3 m, 5 m) is optimized to fully leverage Brocade 10 Gbps solutions.
Active Optical Cable market research Report
The Active Optical Cable market faced many challenges in 2011 from numerous consolidating acquisitions, to the entry of Asian based, low cost suppliers pummeling prices, earthquakes and tsunamis in Japan, to flooding of manufacturing sources in Taiwan and lastly ip battles over who owns what. Stability was regained in 2012 and growth continued strong through the year. But everyone likes the best party and today LightCounting counts 26 players from the AOC market. After a peaceful time period of acquisitions, Mellanox surprised many with its acquisitions of a silicon photonics and a transceiver IC company in early 2013.
In 2012, the market grew 65%, blowing out our previous forecast. It was on top of a stellar 2011. A key difference was the quicker than anticipated up-tick of the 14G InfiniBand FDR AOC segment. We now predict the AOC market to increase 30% to $150 million in 2013.
The InfiniBand market represents the biggest share today and it has already moved on to 14G FDR QSFP+ while traditional Data Centers is sticking with 10G QSFP+ formats. Other protocols with potential AOC opportunities, like SAS, Fibre Channel and PCI Express remain potential markets as their data rates pass 10G.
Copper Cables Mate With Fiber Optic Modules
Interchangeable and hot-swappable with fiber optic modules, the company's SFP+ active direct-attach copper cable assemblies are cost-effective choices to fiber optic transceivers and MPO cables in 10-Gb Ethernet, 8-GB Fibre Channel, and InfiniBand apps. Their active design enables a power consumption of 500 mW per cable end. Active cables also incorporate Rx LOS and Tx disable functionality. All SFP+ cable assemblies meet the MSA spec for signal integrity. Both passive and active cables are available in wire gages from 24 AWG through 30 AWG and incorporate a 360 cable braid-crimp termination that suppresses EMI leakage and offers strain relief.
Increasingly more protocols are moving to higher line rates where copper links start to have issues with reach and EMI and where AOCs offer strong advantages of high data rate, long reach and low price. That is fueling the AOC business, and as a result, facilitating segment growth. Ultimately, there are significant growth and spreading within all facets of the high-speed interconnect market.
