Abstract :
This article describes a single-channel single-mode fiber optic rotary joint for optical data transmission based on well designed TEC fiber collimator. The insertion loss of a fiber optic rotary joint depends on the mechanical misalignments of the fiber collimator. Analysis of the characteristics of TEC fiber and TEC fiber collimator coupling characteristics. Using TEC fiber collimator can reduce the loss of angle tilt misalignment. We fabricated single-channel fiber optic rotary joint which insert loss below 1.27dB. We tested fiber-optic rotary joint by temperature shock from range of -40°C up to + 85°C, our products the average variation of insertion loss is 0.22dB.
