Patent number: 10451795Abstract: A optical fiber having core and cladding regions, a primary coating, and a secondary coating may be defined in part by a curve relating the microbend sensitivity to a ratio of the elastic modulus of the secondary coating to the elastic modulus of the primary coating (as plotted on respective y and x axes). The curve has a substantially peaked shape defined by a positive-slope region and a negative-slope region. The ratio of the elastic modulus of the secondary coating to the elastic modulus of the primary coating is within the positive-slope region.Type: GrantFiled: November 7, 2018Date of Patent: October 22, 2019Assignee: OFS FITEL, LLCInventors: Kariofilis Konstadinidis, David W Peckham, Debra A Simoff

Publication number: 20110188822Abstract: Certain embodiments of the invention may include systems and methods for providing optical fiber coatings to reduce microbend losses. According to an example embodiment of the invention, a method is provided for coating an optical fiber to reduce microbend losses and polarization mode dispersion (PMD). The method includes applying a primary layer to the optical fiber, wherein the optical fiber comprises a core region surrounded by a cladding region. The method includes applying a secondary layer to the primary layer, and curing the primary and secondary layers, wherein the cured primary layer adheres to the cladding region with a minimum pullout adhesion of 6 N/cm, and the cured secondary layer has an in situ modulus of about 700 MPa to about 1200 MPa at room temperature.Type: ApplicationFiled: February 4, 2010Publication date: August 4, 2011Applicant: OFS FITEL, LLCInventors: Kariofilis Konstadinidis, Harry Garner, Peter Haslov, Jinkee Kim, Debra Simoff, Durgesh Vaidya, Yoshihiro Arashitani
