Product Details

Dual model four channel fiber optic rotary joint 
Model number: BTFO-04-02

Fiber Optic slip rings are to optical signals what electrical slip rings are to electrical signals, a means to pass signals across rotating interfaces, particularly when transmitting large amounts of data. Fiber optic slip rings  maintain the intrinsic advantages of fiber end to end. ByTune Electronics has been producing fiber optic slip rings for  20 years.
