Optical Carrier Bandwidth, SONET/SDH/Optical Carrier Facts and Optical Carrier Providers
The two protocols below are standardized by the following:
Synchronous Digital Hierarchy or the acronym SDH is the standard defined by the ETSI or the European Telecommunications Standards Institute
Synchronous Optical Networking or SONET for short is the standard defined by T1.105 from American National Standards Institute and GR-253-CORE from Telcordia.
