The present invention relates to a technique of encoding each data unit of an image and simultaneously, its relevant information indicative of a coding mode of the data unit. The optical fiber cable includes one or more multi-fiber unit tubes having an optical fiber ribbon stack snugly positioned therein. When the panel is in the first position, a pillow may be at least partially received within the storage cavity and it may be hidden. When a pull-out force is applied to the pipe end, the housing retrains each annulus on one side, causing each annulus to tilt from a position substantially perpendicular to the housing.
