Abstract: The specification describes an optical fiber device wherein a LOM is converted to an HOM prior to entering the gain section. The gain section is a few mode fiber that supports the HOM. The output from the gain section, i.e. the HOM, may be utilized as is, or converted back to the LOM. With suitable design of the few mode fiber in the gain section of the device, the effective area, Aeff, may be greater than 1600 μm2. The large mode separation in the gain section reduces mode coupling, allowing greater design freedom and reducing the bend sensitivity of the optical fiber.

Abstract: A visually-distinguishable fiber pair in a shared coating, a method for making uncoated visually-distinguishable fiber, and a fiber-optic system using a visually-distinguishable fiber and a dark fiber in a shared coating are disclosed. To form the visually-distinguishable fiber, a marker is incorporated onto or into uncoated optical fiber. The marker can be applied to the cladding of the fiber, to a buffer layer disposed on the cladding layer, or integrated in a boule from which an optical fiber is drawn. In a further aspect, a marked fiber is paired with an unmarked fiber or a differently-marked fiber creating a visually-distinguishable fiber pair. The distinguishable paired fibers are then coated with plastic.
