Description

technical field

[0001] The invention relates to a distributed temperature sensing optical cable. Background technique

[0002] With the growth of information and the popularization of the network, as an effective means of large-capacity and long-distance transmission, optical cables have been widely used, while traditional optical cables only have the function of transmitting information. Contents of the invention

[0003] The purpose of the present invention is to provide a distributed temperature sensing optical cable, which is used in a distributed temperature monitoring system. The optical cable is used not only as a temperature sensor, but also as a channel for data information transmission.

[0004] The technical solution of the present invention is: a distributed temperature sensing optical cable, including an optical fiber, the optical fiber is covered with a tight sleeve, the tight sleeve is covered with a metal hose, and the metal hose is covered with an aramid f...
