Title:
安全性のためのマルチコア光ファイバ内の冗長コア
Document Type and Number:
Japanese Patent JP6972018
Kind Code:
B2
Abstract:
An optical fiber includes multiple optical cores configured in the fiber including a set of primary cores and an auxiliary core. An interferometric measurement system uses measurements from the multiple primary cores to predict a response from the auxiliary core. The predicted auxiliary core response is compared with the actual auxiliary core response to determine if they differ by more than a predetermined amount, in which case the measurements from the multiple primary cores may be deemed unreliable.
