Today, DWDM technology continues to develop. As the demand for data bandwidth increases, driven by the phenomenal growth of the Internet, the move to optical networking is the focus of new technologies. At this writing, over 800 million people have Internet access and use it regularly. That's over 12% of the entire world's population of 6.4 billion people. The world wide web already hosts over 350 million domain names, 8 billion web pages (that's only the visible, indexed, Internet, the invisible Internet is estimated to be up to 100 times larger), and according to estimates people upload more than 3.5 million new web pages everyday. The Internet dominates traditional voice communication as shown in

The important factor in these developments is the increase in fiber transmission capacity, which has grown by a factor ostrates this trend.

Because of fiber optic technology’s immense potential bandwidth, 50 THz or greater, there are extraordinary possibilities for future fiber optic applications. Already, the push to bring broadband services, including data, audio, and especially video, into the home is well underway. 

Broadband service available to a mass market opens up a wide variety of interactive communications for both consumers and businesses, bringing to reality interactive video networks, interactive banking and shopping from the home, and interactive distance learning. The “last mile” for optical fiber goes from the curb to the television set top, known (FTTC), a reality.
