Abstract: A modular optical tap device as described herein may include a coupler comprising an input configured to be connected to an upstream portion of a network and a first output configured to be connected to a downstream portion of the network. The optical tap device may also include a splitter with an input configured to be connected to a second output of the coupler and one or more outputs configured to be connected to one or more customer devices, wherein the coupler and splitter are modular components in the optical tap device and are configured to be replaced with a second coupler and a second splitter based on a number of customer devices associated with the optical tap device.

Abstract: The present disclosure generally relates to a spherical or curved skateboard wheel that is interchangeable with ordinary, standardized skateboard wheels used in the marketplace. The wheel in some embodiments provides greater weight to the board and protects internal bearings by not resulting in preferential shock positions within each wheel. Further, the spherical wheels allow for higher speed, reduced friction with the road surface when desired, reduction of random bounces of the board during tricks, and increased maneuverability over dry, granular, or soft surfaces.
