Figure 8-1 Fiber-shared virtual path protection

As shown in Figure 8-1, in the fiber-shared virtual path protection, one STM-16,
STM-4, or even STM-1 optical path is logically divided into lower-order or higher-order
paths, which are then combined with other links to form the path-level rings. The
path-level rings can be set with protection schemes such as path protection (PP), MSP,
SNCP, and non-protection (NP).

8.2.5 MS-Shared Optical Path Protection

In the MS-shared optical path protection, an optical interface can be configured with
multiple MSP groups, so that MSP rings can share the same fiber and optical interface.
This function is conditioned on the optical board's capability of processing multiple
sets of independent K bytes. SL64 of the OptiX OSN 7500 support a maximum of four
sets of K bytes and SL16 support two.
Figure 8-2 shows the networking for two-fiber MS-shared optical path protection that
the OptiX OSN 7500 supports.
