| 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 the |
| 1960s, it has increasingly become the medium of |
| choice in communication networks. Optical fiber |
| outperforms copper in bandwidth, transmission |
| distance, noise immunity, and power consumption, |
| making it superior to copper across a broad range of |
| applications. In the past 30 years, fiber optics has |
| replaced nearly all telecommunication copper links, |
| whether in long distance switches, central |
| offices or subscriber loop carriers, with |
| connection to the home being the one exception until |
| now. CATV companies have also followed in the ... |

| 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... |
