Abstract

The invention discloses a light-electricity synchronous conduction fiber which comprises an optical fiber, an external wrapping layer which is wrapped outside the optical fiber and is made from an organic polymer, one or a plurality of wires which are embedded in the external wrapping layer and parallel with the optical fiber. The light-electricity synchronous conduction fiber of the invention adopts the optical fiber to realize the light guide function, and the electric conduction function of the light-electricity synchronous conduction fiber is realized by the wires embedded in the external wrapping layer, the optical fiber and the wires are integrated into the light-electricity synchronous conduction fiber through the external wrapping layer made from the organic polymer, the external wrapping layer plays a role in fixing and protecting the optical fiber and the wires. The number and arrangement mode of the wires can be flexibly designed to fit for all application requirements. Compared with the conventional optical fiber with a protective layer, the light-electricity synchronous conduction fiber is provided with the electric conduction function based on the light guide function. Compared with an optical cable with the optical fiber and a lead of hybrid packaging, the light-electricity synchronous conduction fiber is characterized by light-electricity integration, and reduced volume and weight.

Description

technical field [0001] The invention relates to the field of photoelectric conduction, in particular to a photoelectric simultaneous transmission fiber and a manufacturing method thereof. Background technique [0002] The traditional optical fiber is an all-dielectric optical waveguide drawn from transparent glass materials. It has the characteristics of low optical loss, high mechanical performance and temperature performance. As a means of low-loss optical transmission, it has been widely used in optical communication and optical sensing, etc. optical information applications. Emphasize its optical functions in design and practical application, such as low-loss optical transmission, proper dispersion characteristics, good mode field distribution and so on. In practical applications, optical fiber is often used as an optical transmission channel, or as a passive optical sensing method using the change of transmission characteristics with the external environment.
