FRMMS Fiber Optic Rotary Joint

Product Introduction

The FRMMS type super-integrated multi-channel fiber optic rotary joint can contain 2 to 31 fibers, with an installation diameter of only 38mm. It is one of the smaller diameter fiber optic slip rings with 8 or more channels and is suitable for scenarios with limited installation space. It can be selected as single-mode, multi-mode, or single-multi-mode hybrid and has excellent optical performance.
