BIDI OLP Single Fiber
Optical line automatic switching protection 
Real-time power monitoring
Support automatic switching of primary and secondary routes
Traditional OLP protection requires four valuable core resources. However, in many places, due to insufficient fiber resources, it is impossible to provide excess fiber resources and optical line redundancy protection. In view of the shortage of optical fiber resources and need to optical line redundancy protection, HTF has developed BIDI OLP equipment to solve the problem of optical line protection in the case of insufficient optical cable resources.

OLP-BIDI only needs two fibers to realize the optical line protection function. When the main circuit fiber fails, the receiving end automatically switches to the standby fiber receiving, ensuring communication without blocking operation, improving communication system stability and reliability. It also saves fiber resources.
