With the emergence of cloud computing and accelerate the deployment of large and ultra-large-scale data, data centers, network managers must constantly readjust and further development of the network. Under the impetus of this challenge, a variety of new technologies and new standards have emerged, not only can be used to improve and optimize the network capacity, security and flexibility, while controlling costs. Let us look at the top five trends in 2015 and the network to the user's meaning.

Data center / cloud computing system needs higher bandwidth and lower power consumption and more urgent, AOC is one of the best solutions to meet this demand. AOC (active optical cables) compared with the copper interconnect has many significant advantages, such as lower on the system link transmission power, weighs only a quarter of direct-attached copper, copper-half volume slightly, and room cabling system has better air flow heat dissipation than copper cable bend radius can be made smaller, over longer distances (up to 100 to 300 meters), and the error rate is also better transmission performance , BER can reach 10 ^ -15. Compared with the optical transceiver module, AOC is not exposed due to the presence of optical interface, optical interface clean and contaminated problem does not exist, the system greatly enhanced stability and reliability, and reduce maintenance costs the engine room.
