OXADM dalam Sistem Keselamatan Rangkaian Cincin Metropolitan

The Optical Cross Add Drop Multiplexer (OXADM) is a new hybrid optical device which has the combination of the original Optical Add And Drop Multiplexer (OADM) and Optical Cross Connect (OXC) devices. OXADM is developed based on the study on the demerits of the existing devices and new features are added to the device. OXADM is introduced to increase the survivability in ring architecture network. With its ‘Accumulation’ feature enable the multiplexing protection scheme can be activated where all the signals pass through an optical node are multiplexed onto a single path as a protection/preparation in case breakdown happens at the working line in an optical ring network. Other protection schemes provided by OXADM are the Linear Protection and Ring Protection. OXADM enable the signal to route internally as U turn to segment the breakdown area from the safe area. Both features have differentiated the OXADM with the previous existing device. With this new OXADM device, any breakdown happens in an optical network can be quickly fixed by activating the appropriate protection scheme based on the type and the location of the breakdown. OXADM device is known as the first device that integrates all three network safety mechanisms onto a single device
