Appl. No.:

09/426287

Inventors:

Vidyananda Bangalore Chandraiah - Lawrenceville GA
Kenneth Wade Jackson - Snellville GA

Assignee:

Fitel USA Corporation - Norcross GA

International Classification:

G02B 638

US Classification:

385 75, 385 85, 15 971

Abstract:

The present invention provides an apparatus for cleaning an optical fiber ribbon without splitting the ribbon. The apparatus comprises a first element that has a channel formed therein, which preferably has a width that is substantially equal to the width of an optical fiber ribbon. A ribbon is cleaned by disposing it in the channel and by pulling it through the channel while applying a force to the top surface of the ribbon. The force may be applied, for example, by a user who applies a cleaning cloth to the top surface of the ribbon as it is pulled through the channel. The contact between the channel, the cleaning device and the exterior surface of the ribbon effectuates removal of foreign material from the exterior surface of the ribbon. In accordance with the preferred embodiment, the apparatus further comprises a second element. The second element includes a bottom surface that is disposed over the channel when the first and second elements are placed in their operative positions.

Abstract:

An assembly for curing a linear work product which is passed through a curing oven at high speed along a first path the assembly having a first path altering member, such as a sheave, re-directing the work product through the oven along at least a second path spaced from the first path. A plurality of such sheaves in a first embodiment redirect the work product through the entrance end of the oven for travel along a second path in the same direction as in the first path. In a second embodiment, the path altering members re-direct the work product into the exit end of the oven for travel in a second path in the opposite direction to the first path. Additional curing may be realized by passing the work product through the curing oven in the same or in opposite directions, as desired or as necessary.

Abstract:

A fiber optic cable is disclosed that buffers against loss, where the cable includes an outer jacket, and an optical fiber ribbon disposed within the outer jacket, wherein the ribbon includes more than one optical fiber, and at least two distinct matrix coatings disposed on the optical fibers, the coatings having distinct characteristics. Preferably, the inner coating is relatively soft, with a lower elastic modulus than the relatively stiff, hard outer coating. Also disclosed is a method of buffering loss in an optical fiber transmission, including providing an optical fiber ribbon, wherein the ribbon includes more than one optical fiber, and at least two distinct matrix coatings disposed on the optical fibers, the coatings having distinct characteristics; and transmitting in at least one of the C-band, L-band and U-band of wavelengths.

International Classification:

US Classification:

385114

Abstract:

A method for performing fiber break-out in an optical fiber ribbon, which does not require shutting down the fibers in the ribbon while break-out is being performed, includes the step of placing the ribbon on a smooth surface that is either flat or curved with a radius much greater than the critical bend radius after the matrix material of the ribbon has been softened and swollen. The ribbon is temporarily affixed to the surface, and the softened matrix is then pulled away therefrom. The ribbon is then turned over and temporarily affixed to the surface and the remaining matrix is removed. The fibers that remain are then cleaned with an alcohol solution. In a variation of the method, the matrix is removed by rubbing or abrading it with a textured cloth or pad.

International Classification:

US Classification:

51281R

Abstract:

An alignment sleeve (66) for holding two conically shaped portions (30-30) of plugs (24-24) each of which terminates an optical fiber (25) includes two conically shaped cavities (68, 70) communicating through a common minimal diameter plane (72). After the sleeve has been molded, a tool (100) faced with an abrasive material is inserted into each cavity of the sleeve and turned rotatably while a force is applied in a direction parallel to the longitudinal axis of the tool. This causes material to be removed from the walls defining the cavities so that when the two plugs are inserted into the cavities, the axes of the fibers will be aligned coaxially and the end faces of the fibers will have a predetermined separation. The methods of this invention also may be used to adjust a length measurement of plugs. This is accomplished by inserting a plug into a conically shaped cavity of a tool.

International Classification:

G02B 644

US Classification:

385114

Abstract:

An optical module includes a stack of optical fiber ribbons that are within a buffer encasement, such as a thin sheath, that closely bounds the periphery of the stack. The optical modules can be rectangular, so that the optical modules can be readily stacked in a manner that results in a very space efficient fiber optic cable. The optical modules can be tested prior to being incorporated into the fiber optic cable so as to maximize the probability of the fiber optic cable being fully operable. The sheath cushions all of the sides of the stack. In some optical modules, the stack is movable relative to the sheath and the optical fiber ribbons are movable relative to one another. The sheath is preferably sufficiently rigid to maintain the stack in a stacked configuration, and sufficiently flexible to allow the optical fiber ribbons to slide laterally relative to one another so that, in an end elevation view of the stack, the stack and the sheath can transition from a non-skewed configuration to a skewed configuration. The lateral displacement between the optical fiber ribbons in the skewed configuration is different from the lateral displacement between the optical fiber ribbons in the non-skewed configuration. The stack can be in a longitudinally twisted configuration, and the sheath is sufficiently rigid to hold the stack in the longitudinally twisted configuration.

US Classification:

Abstract:

An optical fiber ribbon in which a plurality of optical fibers are held in an array has a matrix material for bonding to the fibers to form the ribbon. The matrix material has certain characteristics which serve to enhance fiber access, among which are an elastic modulus from 600 to 1200 MPa at room temperature, from 100 to 280 MPa at 100. degree. C. , and from 15 to 45 MPa at temperatures greater than 170. degree. C. The matrix material swells in ethanol more than 15% by volume within 20 minutes, and is virtually immune to the action of cleaning solvents. The matrix material has a surface tension of 20-35 mJ/m. sup. 2 as do the color coding inks which identify the fibers.
