OTN and SDH, WDM relationship

7/13/15  |  Technical Article

OTN with WDM technology, large transmission capacity on the basis of the introduction of the SDH powerful operation, maintenance, management and assignment (OAM) capabilities, while addressing SDH function at the transport layer for lack of inadequate management and maintenance overhead. Using the embedded standard FEC, extensive maintenance and management overhead for large particles service access FEC error correction coding, improve the BER performance, increased light transmission span.
