Abstract: An apparatus having a plurality of multifiber connector interfaces, where some of these multifiber connector interfaces can connect to network equipment in a network using multifiber cables, has an internal mesh implemented in two tiers. The first is configured to rearrange and the second is configured to recombine individual fiber of the different fiber groups. The light path of each transmitter and receiver is matched in order to provide proper optical connections from transmitting to receiving fibers and complex arbitrary network topologies can be implemented with at least 1/N less point to point interconnections, where N=number of channels per multifiber connector interface.

Abstract: A patch cord for transmitting between a single mode fiber (SMF) and a multi-mode fiber (MMFs) has a MMF, SMF, and a photonic crystal fiber (PCF) with a hollow core placed between the SMF and MMF. A mode field diameter (MFD) of the PCF hollow core section is in the range of 16 to 19 microns, the length of the PCF is between 1 cm to 10 cm, the MMF has 50+2 microns core diameter, the SMF has a 6-9 microns core diameter, and the coupling between the PCF mode to the MMF fundamental mode is maximized.

Abstract: An apparatus having input and output ports using a plurality of optical connector adapters, wherein the fiber connections can follow a specific mesh pattern has a plurality of fibers inside the apparatus. The fibers pass through at least one mandrel and are designed to produce a leakage in the transmitted light from each fiber of least −30 dBm, wherein the fiber buffer of fibers around the mandrel are partially stripped in at least one section. The apparatus also has an imaging system consisting of at least a lens, camera sensor and an optical filter are placed in proximity to the fiber striped section wherein the optical filter has spectral properties tuned or partially tuned to the operational wavelength of the network and the optical filter is placed in the light path before the camera sensor.

Abstract: Various implementations of visual inspector attachments for fiber connector cleaners are disclosed. The example fiber optic inspection module includes a camera to capture an image of an end-face, a light source to illuminate the end-face, and a first mirror that reflects light from the light source to the end-face and includes a fixed point that allows the first mirror to pivot. Alternatively, an example fiber optic inspection module includes a camera to capture an image of an end-face, a light source to illuminate the end-face, and a first mirror that reflects light from the light source to the end-face and the first mirror moves in an upward direction.

Abstract: A tool for testing the termination of optical connectors has a housing, a cradle attached to the housing, and a cover removeably attached to the cradle. The cradle is configured to restrain a fiber optic connector and the cover is configured to at least partially block ambient light from reaching the fiber optic connector. In another embodiment, a tool for testing the termination of optical connectors has a housing, a cradle attached to the housing, a launch fiber, and a ferrule adapter. The ferrule adapter is connected such that it rotates about a pivot point on the cradle.

Abstract: The present invention relates in general to communication systems, and more specifically towards methods, systems, and devices that help improve transmission rates and spectral efficiency of intensity modulated (IM) or power modulated channels utilizing multi-level pulse amplitude modulation PAM-M. In an embodiment, the present invention used an iterative algorithm to open the eyes of an eye diagram in a relatively short number of steps. The algorithm, which may not require previous characterization of the channel, utilizes pseudo-random sequences, such as PSBS15 or PRQS10, and adaptive non-linear equalizers to optimize the pre-distortion taps.
