为便于使光纤低衰减这一特性得以发挥的大长度海底光缆传输线路连结及线路故障的维修,光缆相互连接的接头盒是不缺少的。海底光缆接头盒除了使光纤接头部和余长光纤不受敷设或打捞时张力、屈曲和侧压影响,以及免遭海底高水压外,还必须适合于目前使用的敷设船敷设装置。本文从结构方面系统地探讨了刚直型接头盒——光纤接头部和余长光纤放在耐压园管壳体内,光缆固定于壳体两端——的设计。从理论和实验方面明确了接头盒结构设计的基本要素:①能适
To facilitate the low attenuation of fiber this feature can be played to play a large length of the undersea fiber optic cable transmission lines and line maintenance failure, fiber optic cable connector box is not missing. Submarine cable splice boxes, in addition to the fiber splice section and the extra-length optical fiber, are not subject to tension, buckling and lateral pressure when laid or salvaged, as well as being protected from high hydraulic pressures at the seafloor, and must also be suitable for use with laying lashing equipment currently in use. This article systematically explores the design of the rigid connector box - the optical fiber connector part and the extra long optical fiber in the pressure-proof garden tube case and the optical fiber cable in the two ends of the case. From the theoretical and experimental aspects of the basic elements of the structural design of the connector box: ① can adapt
