Network Elements of Optical Transport Network
An optical transport network (OTN) is a digital wrapper that encapsulates frames of data, to allow multiple data sources to be sent on the same channel. OTNs are designed to transport, aggregate, route, supervise, and ensure survivability for digital clients across optical media. The diagram titled "The multiple layers of the OTN network" clearly illustrates how the various layers within the OTN framework work together to ensure smooth transport of different client signals. This article compares OTN interfaces, specifically OTU1, OTU2, OTU3, and OTU4, highlighting the key differences between them.
