2015 is a harvest year to many vendors in optical communication. According to the research “Optical Network Hardware Tracker” by IHS, the global optical network market has increased 3 percent to $ 12.5 billion in 2015. Even, optical interconnection hardware market, which usually has the most fierce competition, also increased in 2015 driven by the whole industry. Will this tendency be kept in 2016 for optical interconnection hardware market? Needs Drive the Market Firstly, the insight of optical interconnection hardware market in last year should be given. In 2015, optical growth is greatly driven by the increasing needs for higher Ethernet speed. This is because the application of advanced technologies like Cloud, Internet of Things, and virtual data center. In addition, the deployment of projects like FTTH (fiber to the home) and 4G network also promoted the optical interconnection hardware market. It is clear that these applications and projects will still be the largest driv...

In today’s data center,  direct attached cable  (DAC) is widely used for interconnection. With 40G migration, DAC becomes more popular, because they can support the high data rate and complete the interconnection in short time effectively. Currently, there are three types of DACs: passive copper cable, active copper cable and active optical cable (AOC). However, different DAC have different performances and prices. Passive or active? Copper or optical? Which DAC is the one you need? In data center, the battle between performance, transmission distance and cost has never ended. This is also true to the selection of DAC for 40G data center interconnection. To find a cost-effective  40G DAC  solution for data center interconnection with reliability and stability, this article will provide you the solution by several rounds of battle between the three types of DAC. Battle Over Transmission Distance The first round of battle is transmission distance which is alwa...

40G transmission is very common in the backbone network now. However, not all the devices and network are upgraded to 40G. To adapting the network between devices and network of different data rate. It is necessary to connection 40G devices to 10G devices for network interconnection. To solve this problem, fanout technology is be accepted and widely used in data center. Fanout products for interconnection is easy to understand. It’s kind of like the water pipeline in our building: water is transferred from the trunk pipeline in a building. Then trunk pipeline fans out into several pipelines that have smaller diameters to bring the water to every house. This post will introduce several Fanout products that are commonly used for 40G data center interconnection. 40G MPO Fanout Cables The first fanout component is 40G MPO fanout cable, also called breakout cable or harness cable. MPO fanout cable is a multi-fiber optical cable with one end terminated with a male/female MPO connector a...
