History

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.
