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 multicore optical fiber including four cores arranged in a linear configuration, the centerline of each core being spaced from the centerline of an adjacent core by a distance x of about 30 microns or less, and each core having a relative refractive index Δ1. A cladding surrounding each of the four cores, the cladding including an inner cladding region with a relative refractive index Δ2, a depressed-index cladding region with a relative refractive index Δ3, and an outer cladding region with a relative refractive index Δ4, wherein Δ1>Δ2>Δ3 and Δ1>Δ4>Δ3. Furthermore, each core of the four cores has a mode field diameter, at a wavelength of 1310 nm, of about 8.1 microns or less, and cross talk between adjacent cores is about −18 dB or less at wavelengths of 1310 nm and 1550 nm per 2 km fiber length.
