A method, system, and apparatus for emulating impairments in a communication system.

Impairment generation

Techniques for performing forward error correction of data to be transmitted over an optical communications channel. The techniques include: receiving data bits; organizing the data bits into an arrangement having a plurality of blocks organized into rows and columns and into a plurality of strands including a first strand of blocks that includes a back portion comprising a first row of the plurality of blocks, and a front portion comprising blocks from at least two different columns in at least two different rows other than the first row of blocks; and encoding at least some of the data bits in the arrangement using a first error correcting code at least in part by generating first parity bits by applying the first error correcting code to first data bits in the front portion of the first strands and second data bits in the back portion of the first strand.

Forward error correction systems and methods

A system, method, and apparatus enabling synchronous and asynchronous data sources to be demapped from an oFrame container using a generic mapping system.

System, method, and apparatus for mapping synchronous and asynchronous data

A method, system, and apparatus for interleaving data including creating a buffer, writing input data, and reading output data out of the buffer.

System, method, and apparatus for interleaving data

A method, apparatus, and system for deinterleaving data.

Deinterleaver

A method, system, and apparatus for transmitting information over an coherent optical link comprising enabling synchronous and asynchronous data sources to be mapped together into a single payload using a generic mapping system which performs decoupling of a clock from each data source, and mapping data from each data source into a tributary of an oFrame.

A method, apparatus, and system for a deinterleaver.
