Abstract: A hollow-core optical fiber may include a substrate having a tubular shape and an inner surface surrounding a central longitudinal axis of the hollow-core optical fiber; a hollow core extending through the substrate along the central longitudinal axis of the hollow-core optical fiber; and a plurality of cladding elements positioned between the central longitudinal axis of the hollow-core optical fiber and the substrate. Each of the plurality of cladding elements may extend in a direction parallel to the central longitudinal axis of the hollow-core optical fiber. Each of the plurality of cladding elements may include a wound glass sheet configured as a spiral, and each of the plurality of cladding elements may contact an interior surface of the substrate.

Abstract: A method for producing a hollow-core preform may include rolling a glass sheet to form a rolled-glass structure; and attaching one or more of the rolled-glass structures to an inner surface of an annular support structure to form a hollow-core preform, wherein the inner surface of the annular support structure defines an interior cavity and the one or more of the rolled-glass structures are positioned within the interior cavity. The hollow-core preform may be drawn into a hollow-core optical fiber.

Abstract: Supporting distributed massive multiple-input multiple-output (DM-MIMO) in a distributed communications system (DCS) is disclosed. The DCS includes multiple remote units each configured to communicate downlink and uplink radio frequency (RF) communications signals with a number of user equipment (UEs) at different UE locations in the DCS. Each remote unit includes multiple antennas, multiple RF chains, and an RF switch circuit configured to dynamically couple the RF chains to a subset of antennas in accordance to the UE locations such that the subset of antennas can be activated to concurrently radiate the downlink RF communications signals and absorb the uplink RF communications signals. By dynamically activating the subset of antennas in accordance to the UE locations, it is possible to optimize signal strength and channel quality for each UE in the DCS, thus making it possible to improve wireless data capacity of the DCS with negligible additional hardware cost.
