    摘要： In today's reconfigurable optical add/drop multiplexer (ROADM) based optical node, ROADMs multiplex (and demultiplex) colored optical signals to form wavelength-division multiplexed (WDM) signals. Transponders connected to the ROADMs' add/drop ports convert noncolored optical signals to colored optical signals (and vice versa). Dedicating transponders to given ports degrades the node's ability to route around network failures. Example embodiments of the invention include an optical node and corresponding method for routing optical signals within an optical node that compensate for this inflexibility. The optical node may include two ROADMs to transmit respective WDM signals onto at least two internode network paths and a routing module that can direct channels of the same wavelength along different internode network paths. Advantageously, a transponder may transmit (receive) different signals at the same wavelength to (from) different network node interfaces within the optical node, thereby improving the optical node's ability to route around network failures.

    摘要翻译： 在当今可重配置的光分插复用器（ROADM）的光节点中，ROADM将彩色光信号复用（和解复用）以形成波分复用（WDM）信号。 连接到ROADM的添加/关闭端口的应答器将未着色的光信号转换为彩色光信号（反之亦然）。 将转发器用于给定端口会降低节点绕过网络故障的能力。 本发明的示例实施例包括光节点和用于在光节点内路由光信号以补偿该不灵活性的相应方法。 光节点可以包括两个ROADM，以将相应的WDM信号发送到至少两个节点间网络路径上，以及路由模块，该路由模块可以沿着不同的节间网络路径来引导相同波长的信道。 有利的是，应答器可以向（从）光节点内的不同网络节点接口发送（接收）相同波长的不同信号，从而提高光节点绕网络故障的路由能力。

    摘要： An apparatus for managing an optical signal includes a system optics card including an add filter, a drop filter, electrical backplane connector, and a mechanical front panel including express input and output ports providing channels to other system optics cards. The card transports information over a first optical transport link and receives information over a second optical transport link. The card identifies at least one network channel on the second optical transport link destined for a client device. The drop filter delivers the identified network channel to the optical converter card for delivery to the client device. The add filter receives client channels from the optical converter card generated by the client device. The card also transports the client channels of the client device over the first optical transport link. The electrical backplane connector is connectable to a chassis for housing the system optics cards and other system optics cards and/or other optics cards.
