Fiber Optic Rotary Joints

SPINNER is one of the world’s leading manufacturers of high-performance rotary joints. Fiber optic rotary joints (FORJs) in particular require exacting optical and mechanical manufacture. And SPINNER ideally meets these requirements. We provide all of the mechanical and optical parts in top quality from a single source. This guarantees a constantly high quality of the SPINNER fibre optic rotary joints, which are characterised by minimum insertion loss values (IL) as well as being maintenance-free.

All fiber-optic components are assembled in an ISO Class 7 cleanroom environment and 100% tested. We build fiber-optic rotary joints available up to 109 channels and any fiber type (single-mode, multi-mode or large-core). The rotary joints transmit signals with low insertion loss, high return loss values, guarantee data transmission at high speeds and/or in EMI/EMC-sensitive environments.
