Fiber optic rotary joints
Fiber optic rotary joints (or simply FORJs) transmit optical signals without contact and without wear over a rotating axis. No electromagnetic noise (EMC protection), no mechanically induced signal losses, and a service life of up to 200 million revolutions.
In the SCHLEIFRING shop you will find a range of FORJ variants: Single-mode version (LC/PC and FC/PC) as well as multi-mode variants (OM1 and OM4) – all as single-channel solutions with protection class IP40 and an operating temperature range from -40 °C to +85 °C.
Individual customizations are always possible: Different fiber lengths (single-mode: up to 4.0 m / multi-mode: up to 2.0 m) and connector types (FC/PC, LC/PC, SC/PC, i.a.) are available upon request. Simply let us know what your specific needs are – we would be pleased to advise you.

What are fiber optic rotary joints?
Fiber optic rotary joints transmit light signals from a stationary to a rotating part without mechanical contact at the transmission surfaces. This is based on the principle of coaxial light guidance: the beam is collimated in the stator and refocused in the rotor. Result: no wear, no EMC problems, full signal integrity even during continuous rotation. The contactless optical transmission is wear-free and supports, depending on the fiber type, data rates up to 100 Gigabit Ethernet.
Single-mode vs. multi-mode
Single-mode FORJs (SM, E9/125 µm) are suitable for applications that require the highest return loss (> 40 dB) and minimum insertion loss (< 1.5 dB) over wide wavelength ranges. Multi-mode FORJs (MM, OM1 or OM4) offer a larger core diameter (50 or 62.5 µm) and are particularly economical for short or medium distances and existing MM infrastructure.
Fields of application for our fiber optic rotary joints
Fiber optic rotary joints are used wherever electrical transmission reaches its limits – e.g., in industrial automation and in special machinery construction (EMC protection), in measuring technology and research, in robotics, in wind turbines, and also in industrial image-processing systems.
