Abstract: Embodiments address optimization of an electrical interface between an optical host device and an optical module device at installation time. Certain methods try each entry in a set of Finite Impulse Response (FIR) filter settings at the host transmitter, while asking the module to measure the signal integrity for each. The module will then provide an indication of which entry was the best choice for signal integrity in the current hardware configuration. Note that for the module to host electrical interface, this same technique can be used in reverse, whereby the host asks the module to configure its transmitting FIR filter, and the host records and keeps track of which filter setting is the best, and then configures the module with that filter setting. In both cases, for modules supporting CMIS (Common Management Interface Specification) for module configuration and control, methods are provided.

Abstract: The present invention is direct to data communication. In a specific embodiment, multiple independent data streams, which are at a first data rate, are transcoded by separate communication pipelines into data blocks. The data blocks, associated with these separate and independent data streams, are multiplexed with alignment markers to generate an output data stream. The output data stream is transmitted at a second data rate, which is higher than the first data rate.
