The coating includes three layers, a first high-modulus coating layer having a Young's modulus greater than 500 MPa, a second high-modulus coating layer having a Young's modulus greater than 500 MPa, and a low-modulus coating layer having a Young's modulus between about 0.20 MPa and 5 MPa. The coating may have the first high-modulus coating layer as the inner layer, the low-modulus coating layer as the intermediate layer, and the second high-modulus coating layer as the outer layer. Alternatively, the coating may have the low-modulus coating layer as the inner layer, first high-modulus coating layer as the intermediate layer, and the second high-modulus coating layer as the outer layer.

Abstract: A method of measuring optical properties of a multi-mode optical fiber during processing of the fiber is described. The method includes: transmitting a light signal through one of the draw end of the multi-mode fiber and a test fiber section toward the other of the draw end and the test fiber section; and receiving a portion of the light signal at one of the draw end and the test fiber section. The method also includes obtaining optical data related to the received portion of the light signal; and analyzing the optical data to determine a property of the multi-mode fiber.

Abstract: A printed circuit board (PCB) composite material includes a polymer layer and a fiber layer encapsulated within the polymer layer. The fiber layer includes a first monolayer of continuous silica fibers longitudinally co-aligned in a first direction. Each continuous silica fiber in the first monolayer extends without discontinuity through the polymer layer such that opposed ends of each continuous silica fiber are adjacent to a perimeter of the polymer layer. The PCB composite material has a dielectric loss tangent of less than or equal to about 0.0015 at 15 GHz or higher frequency. A printed circuit board (PCB) includes the PCB composite material and at least one conductive layer disposed on a side of the PCB composite material.

Abstract: A method of forming an optical fiber includes the steps of forming a soot blank of a silica-based cladding material, wherein the soot blank has a top surface and a bulk density of between 0.8 g/cm2 and 1.6 g/cm3. At least one hole is drilled in the top surface of the soot blank. At least one core cane member is positioned in the at least one hole. The soot blank and at least one soot core cane member are consolidated to form a consolidated preform. The consolidated preform is drawn into an optical fiber.
