Optical Multiplexing Section 1+1 Protection (OMSP)
◆Protects the entire transmission segment, including optical cables and optical amplifiers.
◆Using the multiplexing segment no-optical signal as the criterion to trigger the inversion, when the performance of the active router deteriorates or there is no matte, the system automatically switches to the standby line. Since the APS protocol is not required, the protection switching is stable and fast.
◆It is often used in point-to-point scenarios with a high level of protection.
