Nowadays, the new technologies provide high capacity by using 100 Gb/s channels. These systems are useful, practical, and flexible by using Optical Transport Networks (OTN) and Reconfigurable Optical Add Drop Multiplexers (ROADMs) structures. These new features supply new protection mechanisms over switching on Wavelength Selective Switching (WSS) layer, and Automatically Switching Optical Network (ASON) that is the Generalized Multiprotocol Label Switching (GMPLS) based software runs on the Dense Wavelength Division Multiplexing (DWDM) network elements. In this paper, effects of the optical signal-to-noise ratio (OSNR) are analyzed by increasing the channel lengths on a real long-haul ROADM DWDM network. Then, new cases on channel balancing comes with ROADMs are discoursed. In addition, protection mechanisms are represented and compared by the test results.
