一、前言由于长波长更利于实现长距离、大容量的传输,所以长波长光纤通信特别引人注目,而长波长PIN管连接器是长波长通信中不可缺少的主要组件。我们对它进行了试验分析,得出了光纤与长波长PIN管较为实际的耦合方式的连接器。二、长波长PIN管连接器的主要组件分析 1.光纤在以石英玻璃为基础的光导纤维光谱曲线中存在三个对光通信技术有益“窗口”,即0.85μm、1.3μm和1.55μm三个波长。第二、三个窗口损耗较低,称作长波长低损耗区,见图1。
I. Preface As long wavelength is more conducive to the realization of long-distance, high-capacity transmission, so long-wavelength optical fiber communication is particularly noticeable, and long-wavelength PIN tube connector is an indispensable long-wavelength communications components. We conducted a test analysis of it, and concluded that the fiber and the longer wavelength PIN tube a more practical coupling of the connector. Second, the main components of long-wavelength PIN tube connector analysis 1. Optical fiber in the silica glass-based optical fiber spectral curve there are three beneficial optical communication technology “window”, that is, 0.85μm, 1.3μm and 1.55μm three wavelength. The second and third windows have a lower loss, called the long-wavelength, low-loss area, see Figure 1.
