Optical line protection is 1+1 protection, which can be classified into 1+1 OTS trail protection and 1+1 OMS trail protection. This paper was presented at the 71st Annual Conference for Protective Relay Engineers and can be accessed at: https://doi. For the complete history of this paper, refer to the next page. The communication protocol and the. The OCH layer handles individual client signals; the OMS layer is the part between the OMU/ODU, aggregating multiple OCHs onto a common wavelength; and the OTS layer represents the physical layer of the optical network, and encompasses the actual optical fibers, transmission equipment, and line.
