Abstract: A connector assembly has a male portion and a female portion. The male portion has a pair of electrical contacts and ends of a pair of plastic optical fibers attached. The female portion has a set of through-holes configured to accept the electrical contacts of the male portion and the ends of the plastic optical fibers attached to the male portion such that the plastic optical fibers of the male portion abut plastic optical fibers secured to the female portion within the through-holes of the female portion. In one embodiment, the male portion has a cylindrical shroud configured to accept a cylindrical protrusion on the female portion. The female portion also has a nut rotatably attached with internal threads configured to engage external threads located on the cylindrical shroud of the male portion.

Abstract: The present invention generally relates to the field of fiber optics, and more specifically to optical fibers, methods of manufacturing optical fibers, and methods of classifying optical fibers. In an embodiment, the present invention is a multimode optical fiber which comprises a core and clad material system where the refractive indices of the core and cladding are selected to minimize chromatic dispersion in the 850 nm wavelength window and the refractive index profile is optimized for minimum modal-chromatic dispersion in channels utilizing VCSEL transceivers. Multimode optical fibers according to this embodiment may have increased channel bandwidth.

Abstract: The present invention generally relates to the field of fiber optics, and more particularly, to apparatuses, systems, and methods directed towards improving effective modal bandwidth within a fiber optic communication environment. In an embodiment, a multimode optical fiber in accordance with the present invention comprises a core and cladding material system where the refractive indices of the core and cladding are selected to modify the shape of the profile dispersion parameter, y, as a function of wavelength in such a way that the alpha parameter (α-parameter), which defines the refractive index profile, produces negative relative group delays over a broad range of wavelengths. The new shape of the profile dispersion parameter departs from traditional fibers where the profile dispersion parameter monotonically decreases around the selected wavelength that maximizes the effective modal bandwidth (EMB).

Abstract: A method for compensating for both material or chromatic dispersion and modal dispersion effects in a multimode fiber transmission system is provided. The method includes, but is not limited to measuring a fiber-coupled spatial spectral distribution of the multimode fiber laser transmitter connected with a reference multimode fiber optical cable and determining the amount of chromatic dispersion and modal dispersion present in the reference multimode fiber optic cable. The method also includes, but is not limited to, designing an improved multimode fiber optic cable which compensates for at least a portion of the chromatic dispersion and modal dispersion present in the reference multimode fiber optic cable resulting from the transmitter's fiber-coupled spatial spectral distribution.

Abstract: A new metric applicable to the characterization and design of multimode fiber (MMF) is described. The metric is derived from a Differential Mode Delay (DMD) measurement and when used in combination with industry-standard metrics such as Effective Modal Bandwidth (EMB) and DMD, yields a more accurate prediction of MMF channel link performance as measured by Bit Error Rate (BER) testing. The metric can also be used in the design of MMF for improved bandwidth performance. When implemented as a test algorithm in production, it can be used to select, sort, or verify fiber performance. This process can yield a multimode fiber design with a greater performance margin for a given length, and/or a greater length for a given performance margin.

Abstract: A low latency free-space optical data communication channel has at least two opposing parabolic mirrors for transmitting an optical communication signal in the form of a parallel beam across a free-space channel. The input and output of the collimators are multicore optical fibers. Multiple cores of the multicore optical fibers are positioned at the focal points of the at least two opposing parabolic mirrors and the at least two opposing parabolic mirrors image the optical communications signal in each core of the multiple cores of the multicore fibers into corresponding cores of opposing multicore fibers forming at least one optical communication channel.
