摘要： An optical device (D) is dedicated to the transformation of the propagation mode of optical signals. This device comprises at least a first mode converter (3) that is supplied with signals that are propagated in a first guided mode and that delivers the signals in a multimode fibre (4) partly in the first guided mode and partly in a second guided more of a higher order that the first. The multimode fibre (4) comprises at least first passive filtering means (R) which have the task of converting the first guided mode into at least one dissipative cladding mode in order to prevent or limit the propagation of the signals in this first guided mode while at the same time authorising the propagation of the signals having the second guided mode in the multimode fibre (4).

摘要： An optical fiber telecommunications cable includes micromodules positioned with a longitudinal central cavity formed by a jacket. Two strength members are arranged longitudinally in the jacket and define a bending axis of the cable. Each strength member has an elongated oval cross-sectional shape with a height perpendicular to the bending axis and a width parallel to the bending axis. The height-to-width ratio of each strength member is more than one and no more than two. The optical fiber telecommunications cable has a reduced diameter and good robustness, and can be manufactured at lower cost.

摘要： Disclosed is an optical fiber cable that includes optical fibers and a deformable coupling element enclosed within a buffer tube. The coupling element is formed from a deformable yet substantially incompressible material that is capable of releasably and intermittently coupling the optical fibers to the buffer tube in various orientations. The design of the coupling element layer permits coupling of the optical fibers to the buffer tube without the use of a compressive cushioning layer and yet permits localized movement the optical fibers relative to the buffer tube to account for disparate thermal expansion and to accommodate optical fiber placement.

摘要： A single-mode optical fiber includes a central core, an intermediate cladding, a depressed trench, and an external optical cladding. The central core has a radius r1 and a positive refractive index difference Δn1 with the optical cladding. The intermediate cladding has a radius r2 and a positive refractive index difference Δn2 with the optical cladding, wherein Δn2 is less than Δn1. The depressed trench has a radius r3 and a negative index difference Δn3 with the optical cladding. At a wavelength of 1310 nanometers, the optical fiber has a mode field diameter (MFD) between 8.6 microns and 9.5 microns and, at a wavelength of 1550 nanometers, the optical fiber has bending losses less than about 0.25×10−3 dB/turn for a radius of curvature of 15 millimeters. At a wavelength of 1260 nanometers, attenuation of the LP11 mode to 19.3 dB is achieved over less than 90 meters of fiber.
