Embodiment

[0018] Example: such as figure 1 As shown, a distributed temperature sensing optical cable includes an optical fiber 1, the optical fiber 1 is covered with a tight sleeve 2, the tight sleeve 2 is covered with a metal hose 3, and the metal hose 3 is covered with an aramid fiber The reinforcing layer 4 is covered with a metal braiding layer 5 outside the aramid reinforcing layer 4 , and the metal braiding layer 5 is covered with a low-smoke, halogen-free, flame-retardant sheath 6 .

[0019] The optical fiber 1 is a 50 / 125 μm multimode optical fiber.

[0020] The metal hose 3 is a spiral metal hose.

[0021] Features of the temperature sensing optical cable:

[0022] 1. The optical cable has good mechanical, environmental performance and flame retardant performance, and is suitable for harsh environments.

[0023] 2. Soft, flexible, convenient for construction and maintenance.

[0024] 3. The optical fiber adopts 50 / 125μm multi-mode optical fiber, which has better spatial res...

Abstract

The invention discloses a distributed temperature sensing optical cable, comprising a fiber; a tight tube wraps the fiber, a flexible metallic tube wraps the tight tube, an aramid fiber reinforcing layer wraps the flexible metallic tube, wire sheathing wraps the aramid fiber reinforcing layer and a low-smoke halogen free flame retardant sheath wraps the wire sheathing. The optical cable can be applied to a distributed temperature monitoring system, which can be used as a temperature sensor and a channel for data information transmission.

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...
