Optical signal can not only transmit signal through optical fiber delay coil, but also obtain optical signal with delay. The delay of optical fiber delay line is determined by the length of the optical fiber and the propagation speed of the light in the optical fiber. Optical fiber delay coil is wound by precision winding machine, which has high delay precision, compact structure, anti-seismic and anti-radiation design. We can customize different types and lengths of optical fiber delay coil according to customers’ requirements.
