NPO is CPO

Time:2022-03-19 Views:261
NPO is near packaged optics, which is one of the solutions of CPO, or consider NPO as the first generation of CPO.
The NPO solution solves this problem by relying on a high-performance PCB backplane, the middle layer interposer, which is seated on the motherboard. Because of the larger space in this middle layer, the signal routing from the switch chip to the optical engine is more convenient. The use of the intermediate layer technology also means that the entire PCB board does not need to be upgraded, which greatly reduces the cost, and is not afraid of problems with the light engine on the same bottom plate. NPO uses an intermediate layer, and there are no high-speed signals on the PCB. In the existing 51.2Tbps solution, the existing organic backplane manufacturing capability cannot support such a high-bandwidth connection. The NPO scheme came into being. NPO is the current realistic solution, and many manufacturers can provide it.
