Abstract: Various example embodiments for supporting burst mode communications in an optical communication system may be configured to support burst mode communications based on use of a burst delineation scheme for burst detection. The burst delineation scheme may be based on detection of a delimiter in a burst mode transmission based on selecting, from a received bit stream, a first and second sets of bits, computing first and second error statistics on the first and second sets of bits, computing one or more error metrics based on one or more linear combinations of the first and second error statistics, and determining, based on one or more comparisons based on the one or more error metrics and one or more error thresholds, whether the received bit stream includes a delimiter. The burst delineation scheme for burst detection may be used for burst detection within various types of optical communication networks, including passive optical networks.

Abstract: A test-communication path is provided between chips in a multi-chip package. Externally-accessible JTAG input and output pins are provided to a first chip in the multi-chip package, and this first chip is configured to allow signals received on these JTAG pins to be routed to other chips in the multi-chip package. Control signals provided to the first chip control the routing of the JTAG signals to each chip.
