1光缆传输衰减的温度特性无论是架空敷设还是直埋敷设,光缆通信线路到了冬天均会受寒冻影响,线路故障直线上升,甚至会使光纤通信大面积受阻和不畅,尤以我国北方地区最为严重。虽然光纤的传输特性基本不受温度影响,但温度对光纤的应力有影响,加强芯的延伸率与光纤的延伸率基本是
A fiber optic cable transmission attenuation temperature characteristics Whether it is overhead laying or buried laying, fiber optic cable communication lines in the winter will be affected by the freezing, the line failure rose straight, and even large areas of fiber optic communication will be blocked and poor, especially in northern China The most serious. Although the transmission characteristics of optical fiber are basically unaffected by temperature, the temperature has an influence on the stress of the optical fiber. The enhancement of the elongation of the core and the elongation of the optical fiber is basically
