Ak. Srivastava et al., FAST-LINK CONTROL PROTECTION OF SURVIVING CHANNELS IN MULTIWAVELENGTHOPTICAL NETWORKS, IEEE photonics technology letters, 9(12), 1997, pp. 1667-1669
Link control, a new technique for protecting surviving channels on a p
er-link basis from fast power transients resulting from network reconf
igurations or line failures, is demonstrated in a 560-km eight-amplifi
er wavelength division multiplexed link carrying seven 2.5-Gb/s channe
ls plus the Link control channel.
