text: # G.8201
  
  In Optical Transport Networks, G.8201 is an international standard that defines error performance parameters and objectives for multi-operator international paths.
  
  G.8201 is defined by the International Telecommunications Union's Standardization sector (ITU-T).
  
  ## History
  
  G.8201 was developed by Study Group 13 of ITU-T in 2003. In 2011 a revised version was published (April 2011).
  
  ## Standard
  
  The G.8201 standard defines error performance parameters and objectives for international ODUk paths transported by the optical transport network (OTN).
  
  The standard specifically addresses objectives for international ODUk paths, however the allocation principles can also be applied to the design of error performance for national or private ODUk paths.
