Coriant originates from the Transmission Technology department of Siemens based in Munich, Germany,. In those days the technology evolved from Plesiochronous Digital Hierarchy to Synchronous Digital Hierarchy in the STM-4 / STM-16 level.
In the late 1990s and early 2000s DWDM emerged to allow for even higher transmission capacity. This technology is also named optical transport network, where a set of multiplex and encapsulation hierarchies is standardized.
