COMMUNICATION LIGHT DETECTING STRUCTURE, COMMUNICATION LIGHT DETECTING OPTICAL CONNECTOR INCLUDING THE COMMUNICATION LIGHT DETECTING STRUCTURE, AND COMMUNICATION LIGHT DETECTING OPTICAL CABLE INCLUDING THE COMMUNICATION LIGHT DETECTING STRUCTURE |
摘要 |
A communication light detecting structure includes a communication optical fiber configured to transmit communication light; a leakage optical fiber optically connected to the middle of the communication optical fiber via optical connection portions, the leakage optical fiber being different in core refractive index from the communication optical fiber; and a light detecting unit configured to detect part of the communication light leaking from the optical connection portions as leakage light. A communication light detecting optical connector includes the communication light detecting structure. A communication light detecting optical cable includes the communication light detecting structure. The communication optical fiber and the leakage optical fiber may have the same core diameter. The communication optical fiber and the leakage optical fiber may have the same cladding refractive index. |
