Abstract
A joint for disposing between a rotatable drum and stationary surface equipment. The joint serves as a channel through which optical data from a well access line may be routed through the rotating drum and to the stationary equipment for processing. The optical data may be routed in a manner that allows for multi-fiber transmissions with one fiber dedicated to uphole transmissions and another dedicated to downhole transmissions. This is achieved through embodiments of the joint in spite of the separate optical channels involved sharing the same central axis to allow for data transfer between moving and stationary joint components.
