Co-Packaged Optics (CPO) is an optoelectronic co-packaging technology that integrates an optical module (responsible for optical signal transmission and reception) and a switch ASIC (responsible for electrical signal processing) into the same physical package. Matching SFP modules with switches or media converters is a critical step in building a reliable fiber-optic network. SFP (Small Form-factor Pluggable) is a compact, hot-pluggable network interface module used to connect network devices (switches, routers, firewalls) to fiber optic or copper cables. Optical switching is the process of controlling the destination of individual optical information signals.
