Typical applications
Alternatives that meet or exceed these figures
Engineers often come to us with a Moog part number and leave with an alternative that is easier to source, quicker to deliver or a better fit for the machine. These 2 series from our supply network are the closest match on published figures.
Fibre optic rotary joints that carry single-mode or multi-mode optical channels across rotation for high-bandwidth, interference-free data. Channel counts run from one to fifty.

Figures are the highest published for each series and are not always measured the same way. A higher figure is not automatically a better choice: mounting, duty cycle, feedback, connectors and approvals matter too. An engineer will check the fit against your application before recommending anything.
