An Optical Transmission Technique for Fiber Wire-guided Torpedo

Bidirectional transmission of optical information with high-speed and long-distance in a rapidly laid sin-gle-core guidance optical-cable is a key factor for improving fiber wire-guidance transmission speed, extending trans-mission distance and enhancing information transmission reliability. Considering the characteristics of the torpedo′s fiber wire-guided system, this paper analyzes the techniques about the guidance optical-cable with low dynamic loss, the fiber communication mode selection, the optical signal transmission and receiving, and so on. As a result, an optimum mode of optical transmission for torpedo′s fiber wire-guided system is proposed. This study may provide a reference for improving torpedo′s optical-cable communication capacity.
