Abstract:
1. A method performed by an emulated Optical Network Unit (ONU) platform hardware to execute functions of a plurality of emulated ONUs simultaneously, to thereby enable traffic emulation in a Gigabit-capable Passive Optical Network (GPON) that carries mixed types of emulated ONU traffic and real ONU traffic, the GPON including an Optical Line Termination (OLT) system coupled to the emulated ONU platform hardware, the method comprising the steps of: generating upstream GPON frames by the emulated ONU platform hardware according to respective profiles of the plurality of emulated ONUs, wherein the emulated ONU platform hardware includes a plurality of ONU emulator blocks, and each of the ONU emulator blocks including circuitry to emulate multiple ones of the emulated ONUs simultaneously; sending the upstream GPON frames from the emulated ONU platform hardware to the OLT system, at least a subset of the upstream GPON frames reaching the OLT system via one or more passive optical splitters that couple the emulated ONU platform hardware and a set of real ONUs to the OLT system; and receiving downstream GPON frames form the OLT system by the emulated ONU platform hardware.
