1000 times faster than general optical fiber, NEC succeeded in ultra-high speed communication of 100 Gbps

Demand for high-speed communication, such as distribution services such as high-definition movies and web applications, has increased, but NEC succeeded in ultrahigh-speed communication of 100 Gbps.

It is exactly the next-generation communication standard, which is overwhelming communication speed which is 1000 times that of ordinary household fiber optic communication service (100 Mbps), but will it become usable in ordinary households either?

Details are as below.
NEC successfully succeeded in 100 gigabit optical communication - first in real time experiments: Nikkan Kogyo Shimbun

According to the Nikkan Kogyo Shimbun news report, NEC's 100 Gbps, which is the next generation optical communication standardEthernetIt seems that it succeeded for the first time in a real-time communication experiment by using.

For communication experiments, NEC has developed an optical communication system using a system called "digital coherent" that transmits and receives high-speed data of 100 gigabits per second using the amplitude and phase of light, and next-generation optical communication The standard states that long distance distances of 1,500 kilometers or more, which are sufficient for practical use, can be transmitted with high communication performance.

This is expected to encourage dissemination of 3D video distribution and cloud computing, etc. It is said that it will be improved to a compact system and put into practical use in FY2011.

By the way, although it is a communication speed of 100 Gbps (= 12.5 GB / sec), about two half of the data recorded on one side single layer DVD (4.7 GB) is only one second, and one side single layer Blu - ray disk (25 GB) You can transfer the data recorded in 2 seconds in 2 seconds.
