FIBER OPTICS |
摘要 |
<p>Fiber optics applicable to optical communication in not only 1.3 mum wavelength band but 1.55 mum wavelength band as a transmission medium in a WDM optical communication system capable of transmitting a multi-channel signal light to enable a signal transmission in a broader band. The fiber optics mainly consist of quartz glass and are provided with a core area along a specified axis and a clad area surrounding the core area. The fiber optics with such a structure have, as typical optical characteristics, a cable cutoff wavelength of up to 1260 nm, a transmission loss of up to 0.32 dB/km at a wavelength of 1310 nm, and an OH group-caused loss increase amount of up to 0.3 dB/km at a wavelength of 1380 nm.</p> |
