Patent ID: 8660424

Claim:
A method comprising: at a signal processing module of a scalable signal processing test device that is scalable to test a plurality of data rates, processing one or more sets of source electrical signals according to a first predetermined number of configurable signal processing parameters in order to generate one or more sets of test electrical signals that model electrical signals produced by an optical module from received optical signals in accordance with a plurality of high speed optical standards for optical transmission; selectively disabling and enabling individual transmit links of a scalable number of transmit links to match a number of enabled transmit links to one of the plurality of high speed optical standards; and transmitting the one or more sets of test electrical signals over the enabled transmit links to a host device that is configured to receive the one or more sets of test electrical signals in a format that would normally be produced by an optical module in accordance with the one of the plurality high speed optical standards; wherein at least one of the plurality of transmit links is enabled when transmitting for each of the plurality of high speed optical standards.
