摘要： A data mapping device, a method, and an article of manufacture for adjusting a transmission rate of ISC words are provided. The GFP data mapping device has a FIFO buffer and a transceiver operably coupled to the FIFO buffer. The method includes reading first and second ISC words from the FIFO buffer that were received from a transmitting device. The method further includes determining whether a first number of ISC words stored in the FIFO buffer are greater than a second predetermined number indicating an over-running condition. The method further includes determining whether the first and second ISC words indicate either an ISC continuous sequence of words or an ISC idle sequence of words, if the first number is greater than the second predetermined number. The method further includes deleting the first and second ISC words if the first and second ISC words indicate either the ISC continuous sequence of words or the ISC idle sequence of words. The method further includes reading a third ISC word from the FIFO buffer and transmitting the third ISC word from the transceiver.

摘要： A fiberoptic communications computer program product is presented which allows an open-link condition on one link of a multi-link fiberoptic connection to be propagated to other links of the connection while satisfying the Open Fiber Control safety standard. Each link comprises a duplex link and at least one optical repeater is employed. The at least one optical repeater is adapted to propagate an open-link condition in one link of the multiple duplex links between the links of the fiberoptic connection. Propagating the open-link condition can be accomplished using an out band signal, an electrical wrap mode, or a hybrid approach using both an out band signal and electrical wrap mode. Automatic propagation of a closed-link condition is provided once the originally opened link is closed.

摘要： Laser light is focused in an accurate manner on selected layers in a multilayer optical disk recording system by means of an analysis of output electrical signals from a dithered source which results in the production of an electrical signal which is proportional to an amount by which the parts of the system are to be relatively moved in order to achieve the desired focus on one of the layers.
