FORJs are the optical equivalent of an electrical slip ring. As passive devices, they allow for the low loss transfer of single or multi-mode signals, through rotating interfaces, using optical technology. Rigorously tested in our environmental test facility and in UKAS accredited test facilities to military vibration standards, our FJ1 FORJ's (Multimode, Single Channel) are implemented in the world's leading wind turbine manufacturer and other high-speed data transfer applications. The FJ1 range of FORJs are available with ST direct connection or any specified standard connection leads. Constructed from Stainless Steel, the FORJ range are designed to be chemically resilient and rugged.
