Wavelength-selective cross-connect architecture interconnecting multiwavelength self-healing rings

摘要

Networks using ring architectures provide increased reliability and survivability to the network. The need to connect multiple rings together increases as the network expands. This report focuses on wavelength-selective cross-connect (WSXC) architecures used to interconnect multiwavelength self-healing rings (SHRs).~1 Multiwavelength SHRs use most of the protection concepts incorporated in the SONET SHRs.~(1,2)
