    摘要： A method of performing forward error correction with configurable latency, where a configurable latency algorithm evaluates a target Bit Error Rate (BER) against an actual BER and adjusts the size of a configurable buffer such that the target BER may be achieved when utilizing the smallest buffer size possible. When errors are corrected without the utilization of each of the configurable buffer locations, the algorithm reduces the size of the buffer by y buffer locations; the algorithm may continue to successively reduce the size of said buffer until the minimum number of buffer locations are utilized to achieve the target BER. If the buffer locations have been reduced such that the buffer size is too small and the target BER cannot be achieved, the algorithm may increase the size of the buffer until the minimum number of buffer locations are utilized to achieve the target BER.

    摘要： A present invention discloses a method for performing forward error correction (FEC) in long-haul submarine transmission systems. Data is encoded at a transmitter by serially concatenated, binary Bose-Ray-Chaudhuri-Hochquenghem (BCH) error correcting codes. The invention encodes a stream of data employing a plurality of serially concatenated, binary Bose-Ray-Chaudhuri-Hochquenghem (BCH) error correcting codes, arranging said data into a frame of parallel data blocks (the outer frame) with redundancy bits appended by a BCH(3896, 3824) code; the outer frame is then interleaved to produce a frame of serial data blocks (the intermediate frame); and the final frame (the inner frame) is produced by appending the redundancy bits of the BCH(2040, 1952) code to the intermediate frame. The data, once encoded, is transmitted across a datapath and decoded at the receiver.

    摘要： This algorithm and apparatus provides the ability to determine the amount of skew that should be injected into a high-speed data communications system comprising of a plurality of lanes comprising a data bus on a per lane basis, relative to a reference lane, for the purpose of compensating for inherent system skew. By knowing the relative amount of skew that each lane requires for alignment, an appropriate amount of skew can then be injected on each lane to provide alignment and thus compliancy with relevant standards, such as the SxI-5 standard, in terms of data skew specifications. These relative skew amounts for each transmitting lane are determined using dual loopback methods.
