Introduction to Client 1+1 Protection

The client 1+1 protection is configured with one working wavelength and one protection wavelength that are transmitted in two different routes to protect the OTU board and OCh fiber. The client 1+1 protection protects the OTU board and OCh fibers by using the dual fed and selective receiving function of the OLP/SCS/DCP board.

The client 1+1 protection complies with the following standards or protocols:

ITU-T Recommendation G.798 (Characteristics of optical transport network hierarchy equipment functional blocks)
ITU-T Recommendation G.808.1 (The generic functional models, characteristics and processes associated with various linear protection schemes for connection-oriented layer networks)
