Patent number: 10684434Abstract: A flexible optical ribbon and associated systems and methods of manufacturing are provided. The ribbon includes a plurality of optical transmission elements and an inner layer comprising a cross-linked polymer material and an outer surface. The outer surface of the inner layer includes first areas having first concentrations of uncrosslinked polymer material and second areas having second concentrations of uncrosslinked polymer material. The first concentrations are greater than the second concentrations. The ribbon includes an outer polymer layer having an inner surface interfacing with the outer surface of the inner layer. The outer polymer layer has a higher level of bonding to the inner layer at the first areas than at the second areas due to the ability of the outer polymer material to bond or crosslink with the larger numbers of uncrosslinked polymer material in the first areas.Type: GrantFiled: August 16, 2019Date of Patent: June 16, 2020Assignee: CORNING OPTICAL COMMUNICATIONS LLCInventors: Julie Ann Chalk, David Wesley Chiasson, Barada Kanta Nayak, Rebecca Elizabeth Sistare
