A translucent wavelength switched optical network (WSON), with sparse 3R regenerators to guarantee the signal quality of an optical connection, is a promising paradigm for a metro/ core network. This is because a translucent WSON can achieve performance comparable to that of an all-electronic switching (i.e., opaque) network with far lower network cost and a great reduction in power consumption. Because...
We propose a hybrid all-optical repeater for 10G/1G-EPON mixed bit-rate upstream link. Through a bidirectional transmission experiments, we successfully achieved a total loss budget of 62.1 dB which corresponds to 80km reach and 1024 split.
We experimentally present a lab trial of PCE-based OSNR-aware dynamic restoration in multi-domain GMPLS-enabled translucent WSON, assessing the overall feasibility and quantitatively evaluating the service disruption time and path computation latency during end-to-end lightpath restoration.
Multi-domain resilient translucent WSONs with distributed GMPLS control and centralized PCE/GMPLS control were experimentally demonstrated and quantitatively compared in terms of lightpath provisioning latency and service disruption time in case of an inter-domain link failure.
A resilient translucent optical network controlled by a PCE and extended GMPLS controllers was successfully demonstrated, while quantitatively evaluating the path computation latency and service disruption time during end-to-end lightpath restoration.
