摘要： An optical beam delivery device establishes, from an optical beam, an optical trap that is moveable to different optical trap locations. The device has a first length of fiber through which the optical beam propagates along a propagation path and which has a first refractive index profile (RIP) enabling modification of the propagation path to form an adjusted optical beam movable to propagate along different propagation paths in response to different states of applied perturbation. The device also has a second length of fiber coupled to the first length of fiber and having confinement cores defining a second RIP. The confinement cores occupy different positions in, and correspond to the different optical trap locations at an output of, the second length of fiber.

摘要： A fiber optic cable assembly includes a distribution cable and a tether cable. The distribution cable includes a jacket having a generally flat profile such that the periphery of the distribution cable, when viewed in cross-section, includes two major surfaces of the jacket that are generally flat and are connected by arcuate end surfaces of the jacket. The jacket defines a cavity therein. Further, the distribution cable includes strength members embedded in the jacket and positioned on opposing sides of the cavity. The distribution cable includes a plurality of optical fibers extending through the cavity. The tether cable includes an optical fiber that is fusion spliced to one of the optical fibers of the distribution cable by way of an opening in a side of the jacket of the distribution cable.

摘要： A multicore fiber includes a plurality of unit multicore fibers each including: a plurality of core portions; and a clad portion which is formed in an outer circumference of the core portions and has a refractive index lower than a maximum refractive index of the core portions. The plurality of the core portions have substantially same refractive index profile and different group delays at same wavelength in same propagation mode. The core portions of the multicore fiber are configured so that the core portions of the plurality of the unit multicore fibers are connected in cascade, a maximum value of differential group delays between the core portions of the multicore fiber is smaller than a reduced value of a maximum value of differential group delays between the core portions of each unit multicore fiber as a value in terms of a length of the multicore fiber.

摘要： Methods and systems for distribution of digital data services, radio frequency (RF) communications services, and power are provided for use in optical fiber-based distributed communications systems. Electrical digital data signals are received at a distribution unit. Downlink digital data signals representing the electrical digital data signals are distributed from the distribution unit over a downlink digital data services line to a remote antenna unit (RAU). Uplink digital data signals are received from the RAU over an uplink digital data services line and are distributed to head-end equipment. The distribution unit also receives optical RF communications signals and distributes the optical RF communications signals over at least one RF communications services optical fiber to the RAU. Power is also distributed, from at least one power output of the distribution unit, over at least one power line to the RAU.
