Patent number: 8306382Abstract: Methods, cleavers, and packagings for cleaving an optical fiber using an abrasive medium are disclosed. The abrasive medium may be placed into contact with an optical fiber to induce a flaw in the optical fiber. The optical fiber is broken about the induced flaw to create an end face for fiber optic termination preparations. In one embodiment, a method for cleaving an optical fiber without employing a blade is provided. The method includes providing an optical fiber. A flaw is created in a portion of the optical fiber using a bladeless cleaver comprised of a body and a cleaver structure attached to the body. The cleaver structure is configured to actuate to place an abrasive medium in contact with the portion of the optical fiber to create a flaw in the optical fiber. The method further includes breaking the optical fiber at the flaw to create an end face.Type: GrantFiled: February 1, 2010Date of Patent: November 6, 2012Assignee: Corning Cable Systems LLCInventors: Joshua D.

Publication number: 20120125167Abstract: Imbedded carrier blades for cleaving optical fibers and related cleavers and methods are disclosed. In one embodiment, the blade includes a carrier body that defines a blade edge. At least one cleaving material is imbedded into at least a portion of the carrier body. The at least one cleaving material is additionally exposed on at least a portion of the blade edge to induce a flaw in a portion of an optical fiber contacted by the blade edge. The portion of the optical fiber can be broken about the induced flaw to create an end face for fiber optic termination preparations. Cleaving the optical fiber prepares an end face on the optical fiber to prepare fiber optic terminations, including in the field. The imbedded carrier blade can be disposed in a cleaver to cleave an optical fiber. Methods of cleaving an optical fiber using an imbedded carrier blade are also provided.Type: ApplicationFiled: May 25, 2011Publication date: May 24, 2012Inventors: Todd C. Henke, Michael A.

Patent number: 8155490Abstract: Furcation assemblies (100) for furcating a fiber optic drop cable (10) are disclosed. An example furcation assembly includes a furcation member (110) having an elongate furcation body (112) defining an axial channel (130) with a front section (132). The channel front section is configured to accommodate and be secured to either a buffer tube (30) of a buffered drop cable or a protective cover (20) of an unbuffered drop cable. A flexible guide (150) is secured to the furcation member back end. A flexible protection member (180) slidably fits within the guide back end and is telescopically adjustable relative thereto. To create a cable assembly (200) using the furcation assembly, the furcation member is secured to the drop cable so that the optical fiber (40) carried thereby is passed through the furcation member, through the guide and through the protection member to form an exposed fiber section.Type: GrantFiled: September 30, 2008Date of Patent: April 10, 2012Assignee: Corning Cable Systems LLCInventors: Michael de Jong, Paul X.

Patent number: 8094988Abstract: Apparatus and methods for verifying an acceptable splice termination include propagating light energy into the stub optical fiber of a fiber optic connector, detecting and collecting the amount of optical power emanating from the stub optical fiber at a termination area of the connector, converting the optical power to an electrical signal proportional to the amount of collected optical power, and displaying the electrical signal on a feedback monitor, such as an optical power meter, an LCD bar graph, or an LED. An initial (i.e., reference) value is obtained with the field optical fiber not in physical contact with the stub optical fiber. A final (i.e., terminated) value is obtained with the field optical fiber in physical contact with the stub optical fiber and terminated to the connector. The final value is compared to the initial value to determine whether the change (i.e., difference) is sufficient. Alternatively, the final value is compared to a predetermined limit or threshold.Type: GrantFiled: December 15, 2005Date of Patent: January 10, 2012Assignee: Corning Cable Systems LLCInventors: Bradley S.
