1.2.2 Protected Channels

In optically-protected channels, data traffic flows in two physically separated streams to the receiving node. The configuration of the receiving node determines which traffic flow is transferred to the client layer of the receiving node. Figure 1-2displays an example of optical fiber-protected channels in an ONS 15200 system. This form of optical channel protection is rapid and provides continued system coverage in case of fiber breaks between nodes.
