System and Method for 10/40 Gigabit Ethernet Multi-Lane Gearbox

摘要

A system and method for system and method for 10/40 gigabit Ethernet multi-lane gearbox. In one embodiment, a gearbox device includes one or more inputs on a line side of the device, the one or more inputs being configured to receive four asynchronous 10 Gbit/s Ethernet channels, a marking module that is configured to insert virtual lane markers into four data flows at defined intervals to produce four marked data flows, and a 4:n physical media attachment (PMA) module that is configured to generate one or more higher-rate data flows based on the four marked data flows.
