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. All fiber-optic components are assembled in an ISO Class 7 cleanroom environment and 100% tested.

We also supply combinations of fiber optic rotary joints with radio frequency (RF) rotary joints, contactless power transmission modules, slip rings, multi-media joints and contactless data transmission. Our specialties also include integrated data and power transmission solutions with a small form factor.

SPINNER builds fiber-optic rotary joints available up to 81 channels and any fiber type (single-mode, multi-mode or thick-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.

SPINNER FORJ 1.14/1.14L

The SPINNER FORJ 1.14 features top performance with the most compact dimensions available in SPINNER’s single-channel family. Superior design results in typical insertion losses below 1.0 dB with single-mode fibers. Its small size combined with a low weight of only 18 g enables rotational speeds of 10,000 rpm and more.

For very low-profile designs in which even the minimum bending radius of optical fiber is a constraint, the SPINNER FORJ 1.14L lets the optical beam turn a tight 90° corner. Based on the SPINNER FORJ 1.14, it features equally outstanding performance.

SPINNER FORJ 1.17/1.17pc

The SPINNER FORJ 1.17 is designed for very harsh environments, being able to withstand extremely strong vibrations, jolts, and shocks as well as humidity and seawater. Its design responds to the needs of offshore and underwater applications and boasts a protection rating of IP68. As a special feature, we provide this single-channel rotary joint with pressure compensation for your deep sea applications at depths down to 4,500 m as the SPINNER FORJ 1.17pc.
