Thus, the optical module further provides high speed and long-distance transmission, large capacity, small volume, and light weight and can be broadly applied to high speed optical communications.Type: ApplicationFiled: January 27, 2015Publication date: July 28, 2016Inventors: Xiaohui Tang, Qiang Wang, Yuefeng Sun, Kui Wu, Yuanzhong Xu

Publication number: 20160216468Abstract: A fiber optic cable includes a jacket forming a cavity therein, a stack of fiber optic ribbons located in the cavity, and a strength member embedded in the jacket. The jacket forms a ridge extending into the cavity lengthwise along the fiber optic cable. The ribbon stack is spiraled through the cavity such that corners of the ribbon stack pass by the ridge at intermittent locations along the length of the cable, where interactions between the ridge and the corners of the ribbon stack facilitate coupling of the ribbon stack to the jacket.Type: ApplicationFiled: April 17, 2014Publication date: July 28, 2016Applicant: Corning Optical Communications LLCInventors: Michael John Gimblet, Julian Latelle Greenwood, III, Jason Clay Lail, Eric John Mozdy, David Alan Seddon
