Fiber Optic Rotary Joint

Overview

Hitachi Metals Fiber Optic Rotary Joint allows no-interference optical signal transmission while rotating along the optical fiber axis. FORJs are widely used in cable reel systems from cranes to sensing systems applications where twist-free optical cable is essential. Hitachi Metals brings you high performance, reliability and low cost all in one.
