Abstract
Metro and access networks are facing more and more challenges due to tremendous increase of bandwidth demand and great variety and flexibility of services. Traditional network architectures can only follow with big efforts in terms of both Capex and Opex. Therefore the metro and access part becomes the bottleneck of the whole transport network. With the introduction of PID (Photonic Integrated Device) technology the flexibility of modern OTN transport networks can be brought also to the metro and access area with sustainable Capex and dramatic reduction of Opex, while at the same time the flexibility of the network is increased significantly.
