Optical interconnect on printed circuit boards (OPCBs) is a research focus in the field of communication due to its unique advantages of high transmission rate, low power consumption, low cost, no electromagnetic interference, etc. In this article, firstly the schematic diagrams of optical waveguide and the preparation process of OPCBs are introduced in brief. Then, the progresses of the transmission characteristics, coupling method, environmental reliability, system application, etc. about OPCBs are discussed in detail. Finally, the outlook of its development direction is prospected.
