The dual-pass Fiberoptic Rotary Joint (FORJ) connects two independent fiber channels simultaneously. It allows uninterrupted transmission of optical signals while rotating along the common mechanical axis. Our unique patented design provides customers with a significant advantage in size, performance, availability, and cost. The device accommodates two standard multimode fibers.

Note: The MJ2 model is specifically designed for LED types of light sources only. If your application is laser-based, check out our ZJn or MXn series FORJs. They are also good for singlemode fibers. All insertion loss and return loss measurements are performed by joining the FORJ to the light source through a fusion splice (without the use of connectors). Insertion loss of all receptacle types of FORJs, such as RST, RFC, and RFCX, are measured with connectors of similar type. Their return loss is not measured.
