摘要： A multi-bit packet carried on an optical network includes a marker pulse. A bit-rate clock for use in a bit-level operation on the packet is generated by replicating the marker pulse. The bit-level operation may comprise retiming, regeneration or demultiplexing. The marker pulse may be distinguished by a fixed, bit-asynchronous time relationship to the rest of the packet.

摘要： An optical device includes a 50-50 cross-coupler having a pair of ports optically coupled by a waveguide which includes a portion of material having a non-linear refractive index with a relaxation time such that the effect on the non-linear portion of a first pulse passing through the portion last long enough to affect the phase of a second pulse relative to the first. It finds application as a logic element, optical amplifier modulator and the like.

摘要： An optical regenerator suitable for use with optical signals has two stages. An incoming optical signal to be regenerated passes first through a data division stage. This divides the optical data stream into a number of data streams at a bit rate lower than the original optical signal. These data streams then pass to a regeneration stage. In the regeneration stage, there are a number of optical gates. Each gate receives one of the optical data streams at its control input. An optical clock stream at the lower or at a multiple thereof passes through the optical gates. The outputs of these optical gates are connected in common to the optical output of the regenerator and provide a bit-interleaved regenerated optical data stream at the output.

摘要： A roller shaft mount or support secures a shaft end of a conveyor roller at and between opposite sidewalls of a conveyor. The shaft support includes a mounting portion mountable to a sidewall of the conveyor and a clamping portion. The clamping portion is movably attached to the mounting portion and movable relative thereto. The shaft support receives a roller shaft at least partially therethrough. The clamping portion is movable relative to the mounting portion so as to clamp the roller shaft within the shaft support in response to movement of the clamping portion relative to the mounting portion. The clamping portion may move along a ramped surface toward and into engagement with the shaft of the roller in response to adjustment of a fastener to clamp the roller shaft within the shaft support.
