Abstract
A rotatable capsule for a fiber optic rotary joint and a method of using thereof is disclosed. The rotatable capsule may have a housing with one or more sections, where inside the housing there may exist multiple chambers. The rotatable capsule may be designed to be submerged under water and withstand high pressure loads during operation. A first chamber may be designed to support one or more shaft seals between a rotatable shaft and the housing of the capsule by equalizing the pressure of the outside environment with the usage of a high viscosity liquid fluid that is non-conductive and non-compressible. At least one other chamber may be designed to hold different portions of the fiber optic rotary joint and be sealed from the first chamber to provide a second level of sealing.
