Patent number: 7231558Abstract: An bit error rate tester for use in connection with a high speed networks. The bit error rate tester includes transmit and receive ports, as well as a sequence generator, memory, synchronizer, sequence start detect module, and comparator. The sequence generator generates a bit sequence for transmission through a network path. The bit sequence returns to the bit error rate tester by way of the receive port. The synchronizer then bit-aligns the received bit sequence to compensate for idles/fill words added/dropped as the bit sequence transited the network. The synchronized bit sequence is passed to the start word detector which detects start and end words in the bit sequence and instructs the comparator to compare only data between the start and end words. The comparator compares the received bit sequence with a copy of the transmitted bit sequence regenerated from the memory, and calculates a bit error rate.Type: GrantFiled: April 24, 2003Date of Patent: June 12, 2007Assignee: Finisar CorporationInventors: Paul Gentieu, Chris Cicchetti, Arthur M.

Patent number: 7032139Abstract: The present invention is a bit error rate tester that may operate on network paths having devices that add or drop idles within a transmitted bit sequence. In particular, the bit sequence determines whether a received bit sequence is synchronized. If the received sequence is not synchronized or if a certain event/threshold is reached, then the bit error rate tester re-synchronizes the sequence prior to analysis. Also, the bit error rate detector is able to operate on high-speed networks and provide bit granularity measurements.Type: GrantFiled: June 24, 2002Date of Patent: April 18, 2006Assignee: Finisar CorporationInventors: Farhad Iryami, Paul Gentieu
