Abstract: A system and method are provided for transmitting and receiving asynchronous channels of information via a SerDes Frame Interface (SFI) 4.2 interface. The SerDes device accepts a plurality of channels operating at asynchronous channel clock rates. Bytes of data from each channel are loaded into a source at the channel clock rates. Once loaded, the bytes of data for each channel are drained from the source at a line clock rate and interleaved into four 64-bit segments. A 2-bit control word is added to each segment, creating 66/64-bit data blocks. The control word indicates the validity of bytes of data within the 66/64-bit data blocks. Then, the 66/64 bit data blocks are transmitted via a SFI4.2 interface in four lanes, at a rate proportional to the line clock rate.

Abstract: Techniques for multiplexing and demultiplexing signals for optical transport networks are presented. A network component comprises a multiplexer component that multiplexes a plurality of signals having a first signal format to produce a multiplexed signal in accordance with a second signal format, while maintaining error correction code (ECC) of such signals and without decoding such signals and associated ECC. The multiplexer component interleaves the plurality of signals with stuffing and adds overhead without generating new ECC. A second network component receives the multiplexed signal as part of a frame in accordance with the second signal format. A demultiplexer component of the second network component demultiplexes the multiplexed signal using the original ECC associated with the plurality of signals, wherein the second network element removes and filters the stuffing from the multiplexed signal and produces a plurality of demultiplexed signals as an output, in accordance with the first signal format.

Abstract: A high-capacity digital communications system and method of transporting 10 GbE LAN packets between user devices over an OTN network that allows the packets to be transported in a manner that is transparent to the destination device(s) on the network. The digital communications system includes an OTN network, and at least one source device and at least one destination device connected to the network via respective 10 Gbase-R interfaces. The system transports 10 GbE LAN data packets over the OTN network by performing decoding on the packets to recover the preamble and variable length data contained in each packet, removing the IPG between successive packets in the stream, encapsulating the packets including the respective preambles and data, and mapping the encapsulated packets to the overhead and payload areas of ODUk frames. The packets are then transported over the OTN network from the source device to the destination device.

Abstract: A digital communications system that can asynchronously map/de-map digital signals from one clock domain to another, while reducing mapping jitter levels and permitting higher levels of integration. The digital communications system includes an asynchronous stuff bit insertion circuit, an asynchronous stuff bit removal circuit, and a communications network connected therebetween. The asynchronous stuff bit insertion circuit includes a first elastic store, a barrel shifter, and a stuffing circuit. The asynchronous stuff bit removal circuit includes a de-stuffing circuit, a second elastic store, and a frequency control path including a phase-locked loop having a variable divider circuit, the operation of which is controlled based on the presence/absence of stuff bits in the data provided to the de-stuffing circuit. By employing the first elastic store for temporary gross data frame storage and the barrel shifter for temporary fine data frame storage to reduce the number of gates in the asynchronous stuff bit insertion circuit, integration levels are increased. Further, by employing the frequency control path in the asynchronous stuff bit removal circuit to recover the clock signal of the first clock domain, mapping jitter levels in the digital communications system are reduced.
