Abstract

The invention provides an optical fiber and an optical fiber communication system, relates to the technical field of communication sensing, can realize a communication function and a sensing function in the same optical fiber, and avoids the problems of repeated construction of optical fiber laying and waste of optical fiber resources. The optical fiber comprises at least two fiber cores and a cladding, the cladding comprises at least two groove structures, the fiber cores are arranged in the groove structures, the refractive index of the fiber cores is larger than that of the cladding, the at least two fiber cores comprise a first fiber core, and the first fiber core comprises a dopant used for adjusting the scattering rate.

Description

technical field [0001] The present application relates to the technical field of communication sensing, in particular to an optical fiber and an optical fiber communication system. Background technique [0002] With the vigorous development of information technologies such as 6th generation mobile networks (6G for short) and Internet of Things technology, the optical fiber communication system as the infrastructure of information technology has attracted attention from various fields. [0003] Among them, in petrochemical, high-voltage power transmission, geological structure and other fields, it is not only necessary to lay optical fibers to build optical fiber communication systems to achieve communication functions, but also to lay sensing elements to build sensing systems to achieve sensing functions. Existing sensing systems often use optical fibers as the transmission medium for sensing elements and sensing signals, so as to monitor the environmental parameters of the ...
