Optical layers
WebThin-film optics is the branch of optics that deals with very thin structured layers of different materials. In order to exhibit thin-film optics, the thickness of the layers of material must be similar to the coherence length; for visible light it is most often observed between 200 and 1000 nm of thickness. Layers at this scale can have remarkable reflective properties due … WebThere are six distinct layers to this format. OPU: Optical Channel Payload Unit. This contains the encapsulated client data, and a header describing the type of that data. It is analogous to the ‘Path’ layer in SONET/SDH. ODU: Optical Data Unit.
