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: The present invention is directed to a protection switch disposed at a node in a two-fiber optical channel ring. The protection switch includes a wavelength selective switch (WSS) (20) coupled to the two-fiber optical channel protection ring. The WSS (20) is configured to selectively drop at least one wavelength channel propagating in the two-fiber optical channel protection ring. A dynamic spectral equalizer (DSE) (30) is coupled to the two-fiber optical channel protection ring. The DSE (30) 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 translation: 本发明涉及一种设置在双纤维光通道环中的节点处的保护开关。 保护开关包括耦合到双光纤光通道保护环的波长选择开关（WSS）（20）。 WSS（20）被配置为选择性地丢弃在双纤维光通道保护环中传播的至少一个波长信道。 动态频谱均衡器（DSE）（30）耦合到双光纤光通道保护环。 DSE（30）被配置为基本上阻挡对应于至少一个波长信道的波长，并且光学地管理不对应于至少一个波长信道的至少一个快速波长信道。
