Methods for modifying multi-mode optical fiber manufacturing processes are disclosed. In one embodiment, a method for modifying a process for manufacturing multi-mode optical fiber includes measuring at least one characteristic of a multi-mode optical fiber. The at least one characteristic is a modal bandwidth or a differential mode delay at one or more wavelengths. The method further includes determining a measured peak wavelength of the multi-mode optical fiber based on the measured characteristic, determining a difference between the target peak wavelength and the measured peak wavelength, and modifying the process for manufacturing multi-mode optical fiber based on the difference between the target peak wavelength and the measured peak wavelength.

Systems and methods for inspecting wound optical fiber to detect and characterize defects are disclosed. The method includes illuminating the wound optical fiber with light from a light source and capturing a digital image based on measurement light that is redirected by the wound optical fiber to a digital camera. The method also includes processing the digital image with a computer to detect and characterize the defects. The types of defects that can be detected using the systems and methods disclosed herein include bubbles, abrasions, punctures, scratches, surface contamination, winding errors, periodic dimensional errors, aperiodic dimensional errors and dents.

An optical fiber inventory selection system selects optical fibers from inventory for use in a communication network. In one embodiment, the system generates an internal specification of requirements to select optical fiber reels from an inventory to be used as components in spans, such as dispersion managed spans, wherein at least one of the selected optical fiber reels is identified to have an amount of optical fiber on the reel cut back to a reduced length. The spans can then be selected to satisfy customer requirements or standardized requirements for a communication network that may include a plurality of cables and paths.
