Try to imagine a time when one lone cable will be able to carry
* One million DVD or high-definition television signals
* Six million high-speed Internet connections
* One hundred million dialup Internet connections
If this sounds like the type of data and video networking that only your grandchildren will be able to enjoy, don't be too despondent. The truth of the matter is that fiber optics makes this capacity possible today-on just a single strand of fiber!
The capacities of fiber optics are amazing, and every day there seems to be new ways to pack even more data on fiber. One day, your grandchildren might look back and ask, "Fiber could only carry a million HDTV channels at the turn of the century?" Although fiber optic systems were first conceived early in the twentieth century (the basics of light and fiber a couple hundred years before that), it wasn't until the mid-1970s that fiber optics were first deployed for communications. Since then, fiber-based communications have been getting more robust, and it is only now that optical networking is coming into its own.
