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 breakout device that separates and protects individual fibers from a ribbon fiber cable. The breakout device includes a collet assembly that secures the ribbon fiber cable in the device. The collet assembly includes a base having a tapered internal bore, a collet positioned within the internal bore and a nut positioned over the base. The collet includes an aperture that receives the ribbon fiber cable and fingers that retain the ribbon fiber cable in the collet. When the nut is tightened over the base, the nut forces the collet further into the base thereby compressing the fingers axially along the cable.

Abstract: The location and type of equipment shelf installed in an optical fiber distribution frame is detected and transmitted to a software management system automatically. A plurality of photo transceivers, arrayed on the frame, detects encoded indicia on each shelf. The coded information is inventoried into a database and displayed in a virtual graphical representation of the frame.

Abstract: A method is provided for utilization of previously unusable space within an optical fiber distribution frame for electrical fuses, power, ground, and electrical communications and control for optical fiber management. These components as well as optical fiber installation tools, maintenance tools, and spare parts are housed within spaces defined by upper and lower raceways.
