Why the color Green is so much emphasized in the news world of internet and not only. Mostly our searches for information depend what are our interests and what is our background of knowledge but the actuality of the problems concerning the issues of global warming, energy efficiency are vivid and undoubtedly, the topics do not leave the first three or five news stories on different web sites. Each sphere covers the issue in individual manner and with different approaches.

Though, the purpose is the same for everybody, to make the world healthier than it is today. In past centuries while creating computers of the size of a room, hardly anybody could think what might be the possible consequences of not only computers but technology in general and other human harmful activities.

And today the leading companies which have the focus in this direction work on this issue intensively. One of them is D-Link. It strives for excellence as an award winning designer, developer, and manufacturer of networking, broadband, digital electronics, voice and data communications solutions for the digital home, Small to Medium Business (SMB), and Workgroup to Enterprise environments.

One of the last products the company created is Green Ethernet technology and its new environmental-friendly series of SOHO Gigabit switches that decreases energy costs through the reduction of power consumption without sacrificing any operational performance or functionality.

Karien Wood, Marketing Manager for D-Link South Africa, admits: “D-Link's Green Ethernet technology conserves energy by recognizing when a port is active or inactive to adjust its power accordingly, thus offering benefits to Home and SOHO users who may not need perpetual use of their computers or all the ports on their switches. It is also capable of altering the power usage relative to the length of its cable, and conserving the use of energy for both the user and the environment without suffering any loss of performance."

As D-Link emphasizes the main features of the new product are as follows:

D-Link's Green Ethernet technology
D-link's Green Ethernet technology can detect a link's status and cable length, and adjust power usage accordingly. By reducing power consumption, less heat is produced, resulting in extended product life and lower operating costs.

Power conservation when links are idle
Even when a computer is shut down, switches often remain on and continue to consume considerable amount of power. Using D-link's Green Ethernet technology, the new switches can detect when a computer is turned off, and then respond accordingly by changing into power standby mode, thus reducing power usage for that port.

Optimized power usage on dynamic detection of cable length
Switches normally send full power to cables regardless of the actual length. Using D-link's Green Ethernet technology, the switches can analyze the cable's length and adjust the power accordingly. Since the cable length used by Home/SOHO users is mostly less than 20m, power consumption can be significantly reduced.

On the basis of researches and market demand evaluation D-Link is going to improve the technology that will be to advantage to the environment that needs human care.

The efforts of D-Link are not enough for the world that is under very serous threats but it is one step forward.
