| HD in Your Life |
| |
| At present, almost all broadband subscribers |
| use copper based technology, such as xDSL |
| and cable modem, or wireless based |
| technology. Outside the data center, the fiber |
| optics penetration rate is less than 10% in |
| last-mile applications. If a user wishes |
| simultaneously to surf web pages, download |
| songs, send and receive photographs, and |
| watch streaming video with HD quality, then |
| the bandwidth provided by today’s cable |
| modems, xDSL and wireless services is |
| probably not sufficient. |

| Communication Networks |
| |
| Ever since fiber optics was invented in 1960s, its de- |
| velopment seems to be irresistible in communication |
| networks. Fiber optics outperforming copper in bend |
| width, transmission distance, and noise immunity ma- |
| ke it possible to do things not possible with copper |
| wire. In the past 30 years, fiber was replacing all tel- |
| ecommunication copper links, from long distance sw- |
| itches, central offices to subscriber loop carriers.... |
|
| Fiber Toughening Mechanism |
| |
| Modern-day applications for optical fiber require |
| mechanical properties well beyond the requirements |
| for conventional optical fiber,whose main application |
| is in long distance telecommunication and where |
| optical performance alone has always been the main |
| priority... |
