NPO, or Near-Packaged Optics, is a highly integrated optical interconnect solution that falls between traditional pluggable optical modules and CPO. Near-packaged optics (NPO) helps send data faster. It puts the optical engine close to the switching chip. You do not have to redesign your whole system. This technology uses less power. LPO (Linear-drive Pluggable Optics), NPO (Near Package Optics), and CPO (Co-Packaged Optics) architectures are becoming core areas of industry focus. By shortening the electro-optical conversion path and improving bandwidth density and energy efficiency, they are redefining the system. Near Packaged Optics (NPO) is a key innovation for next-generation data center architectures, where optical components are placed close to switching ASICs, significantly increasing data bandwidth and energy efficiency while maintaining system flexibility.
