Abstract

The invention discloses a polarization maintaining optical fiber which comprises a fiber core with an annular cross section, first to N stress bars and a coating. The first to N stress bars are arranged around the fiber core, and the axial directions of the stress bars are parallel to the axial direction of the fiber core, wherein N is larger than or equal to 2 and smaller than or equal to 10. The coating wraps the fiber core and the first to N stress bars. According to the polarization maintaining optical fiber, long-distance simultaneous transmission of multiple modes can be achieved, the communication capacity is large, and the spectrum utilization rate is high.

Description

technical field [0001] The invention relates to the technical field of communication equipment, in particular to a polarization-maintaining ring-core optical fiber. Background technique [0002] Most of the communication optical fibers in the related art are single-mode optical fibers, which cannot transmit multiple modes at the same time, so the communication capacity is small and the spectrum utilization rate is low. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes a polarization-maintaining ring-core fiber, which can realize long-distance simultaneous transmission of multiple modes, and has the advantages of large communication capacity and high spectral utilization. [0004] A polarization-maintaining ring-core optical fiber according to an embodiment of the present invention includes: a core with a ring-shaped cross section; first to...
