Abstract: The present invention is directed to a protection switch disposed at a node in a two-fiber optical channel protection ring. The protection switch includes a wavelength selective switch (WSS) coupled to the two-fiber optical channel protection ring. The WSS is configured to selectively drop at least one wavelength channel propagating in the two-fiber optical channel protection ring. A dynamic spectral equalizer (DSE) is coupled to the two-fiber optical channel protection ring. The DSE is configured to substantially block wavelengths corresponding to the at least one wavelength channel, and to optically manage at least one express wavelength channel not corresponding to the at least one wavelength channel.

Abstract: An optical fiber link suitable for use in a mode division multiplexing (MDM) optical transmission system is disclosed. The link has a first optical fiber having a core which supports the propagation and transmission of an optical signal with X LP modes at a wavelength of 1550 nm, wherein X is an integer greater than 1 and less than or equal to 20 the first fiber having a positive differential mode group delay between the LP01 and LP11 modes at a wavelength between 1530-1570. The link also has a second optical fiber having a core which supports the propagation and transmission of an optical signal with Y LP modes at a wavelength of 1550 nm, wherein Y is an integer greater than 1 and less than or equal to 20 said optical fiber having a negative differential mode group delay between the LP01 and LP11 modes at a wavelength between 1530-1570.
