This disclosure provides systems, methods and apparatus of establishing a free-space communication link through a medium. The medium can be an occluded environment with increased absorption and/or scattering effects. The free-space communication link includes a transmitter configured to transmit an optical signal at a wavelength suitable for transmission through the medium without suffering excessive optical losses due to absorption and/or scattering effects. The free-space communication link includes a receiver configured to receive the transmitted optical signal. The transmitter-receiver pair is configured to efficiently transmit optical signals at the suitable wavelength over a distance between about 1 mm and about 50 m. The transmitter and the receiver can be configured as portions of a fiber-optic connector assembly that can be used to connect two fiber-optic cables in an occluded environment.

Methods, apparatus, and computer readable storage media reduce or eliminate network traffic meeting criteria. In some aspects, network traffic transmitted by one or more source nodes to one or more destination nodes may comprise a denial of service attack against the destination node(s). At least a portion of the denial of service attack traffic may be reduced or eliminated with the disclosed methods and apparatus. In one aspect, a method of managing undesirable network traffic transmitted from a source node to a destination node over a communications network includes receiving a notification of a routing rule change, authenticating the notification, determining a network routing rule based on the notification, applying the network routing rule, determining a network path toward the source node, determining an entity based on the network path, and transmitting a notification of the routing rule change to the entity.

Fabrication techniques for polishing fibers engaged in grooves on substrates. A protection template assembly is disclosed to protect the unpolished portions of fibers. Chemical mechanical polishing may be used to achieve high fabrication throughput and high polishing uniformity. Optical monitoring may be used to monitor the polishing in real time.

A radiation detection device for gamma radiation is disclosed having an array of crystals optically positioned adjacent an optional collimator, the crystals emitting visible light upon illumination by the incident gamma radiation. An array of photodetectors is optically positioned adjacent the crystal array on the side of the crystal array opposite that of the collimator. A select photodetector in the photodetector array provides an output signal when the select photodetector is illuminated by the visible light. An integrated circuit having an input from the output signals of said array of photodetectors is used to process and output signals indicative of the intensity and position of the gamma radiation.
