Virtual concatenation (VCAT) is an inverse multiplexing technique creating a large capacity payload container distributed over multiple smaller capacity TDM signals. These signals may be transported or routed independently.Virtual concatenation has been defined for SONET / SDH, OTN and PDH path signals.CAT helps in providing services at a lower cost and more quickly than contiguous concatenation. However, it creates differential delay whereby each path that is created, represented by a VT has a different propagational delay across the network. The difference in these delays is called differential delay (D).
