摘要：随着近几年的发展，原材料价格因素不再凸显，生产技术趋于成熟，以及《YD/T 3350,1-2018
通信用全干式室外光缆》的发布，全干式室外光缆已经适合国内新一代网络建设的需要。全干式室外光缆
将得到广泛的应用，特别是在垂直布线、阻燃等领域性能上照比油膏填充式性能更为优异。但是全干式光
缆对比传统的油膏填充式光缆在的渗水原理不同，全干式光缆内会进入少量的水被阻水纱吸收，形成阻水
凝胶阻水。对于光缆内部进水冰冻后的情况，是否会对光纤传输性能产生不利影响，业内相关的验证实验
还少。为此，本文使用全干式光缆进行高寒条件下的冰冻试验，验证光缆套管内进水冰冻后是否会对光纤
衰减产生影响。

Abstract

With the development in recent years, the raw material price factor is no longer prominent, the
production technology has matured, and the release of "YD/T 3350,1-2018 Communication Dry-dry
Outdoor Optical Cable", the dry-dry outdoor optical cable has become suitable for domestic new The
need for a generation of network construction.The all-dry outdoor optical cable will be widely used,
especially in the performance of vertical wiring, flame retardant and other fields than the ointment-filled
performance.However, compared with the traditional ointment-filled optical cable, the fully dry optical
cable is still insufficient in terms of water penetration. Especially after the water in the optical cable is
frozen, whether it will adversely affect the transmission performance of the optical fiber, there are few
related verification experiments in the industry.To this end, this article uses a completely dry optical cable
to conduct freezing tests under different conditions to verify whether the water in the optical cable sleeve
will affect the attenuation of the optical fiber after freezing.
