All-Optical Packet Switches (OPS) are considered as a good candidate for future ultra-fast communications as they do not require Optical-Electronic-Optical (O/E/O) conversions. However, currently there is still no practical optical random access memory available, which makes it difficult to reduce packet loss to an acceptable level in OPS. Thus, hybrid optical/electronic switch architectures, such as the switch proposed in which the authors refer to as the OpCut switch in this paper, are promising alternatives due to their potential to achieve ultra-low packet loss and packet delay.
