MULTI-CORE OPTICAL FIBER AND OPTICAL COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide multi-core optical fiber that allows single-core optical fiber to be replaced with the multi-core optical fiber per sub-section obtained by dividing a section between communication devices.SOLUTION: Multi-core optical fiber 4 comprises one first core 41 and at least one second core 42. The first core 41 is arranged at the same position as single-core optical fiber in the cross-section of the multi-core optical fiber 4.SELECTED DRAWING: Figure 2
