FR-J Reel-Specific Rotary Joint

Product Introduction

The FR-J model multi-channel fiber optic rotary joint is a product specially developed by our company for the cable reel industry. Compared to fiber optic couplers with limited number ofturns,this product has the advantages of no limit on the number of turns used, allowing high rotation speed, and long service life.In addition, compared to conventional fiber optic rotary joint, this product has a very high cost performance, making it the optimal solution for solving the problem of optical cable rotation connection in the optical cable reel industry.
