Objectives

The main goal of PASSION project is the development of application driven photonic technologies supporting an innovative transceiver and node featuring different levels of aggregation (in spectrum, polarization and space) for an envisaged network architecture able to match the growing traffic demand in metro connections.
The proposed approach is capable to establish high capacity connection for metro network distances (a few hundreds of km) with high-throughput, low-cost, energy-efficient, reduced-footprint devices for massive deployment. End-to-end metro transport for novel services and business is achieved with dynamic SDN control of the different systems and subsystems to ensure metro connectivity and deployment of services.
In order to pursue its ambitious goal, PASSION is based on the design and feasibility demonstration of photonic components and sub-systems, targeting five main science and technology (S&T) Objectives:

Objective 1: Design and development of photonic technologies for the realization of a new generation of energy-efficient and compact transmitter (Tx) modules for the metro network enabling up to Tb/s capacity per PIC.

Objective 2: Design and development of photonic technologies for the realization of a new generation of compact, flexible receiver (Rx) modules for the metro network, able to sustain the PASSION sliceable-bandwidth/bitrate approach.

Objective 3: Development of energy-efficient and small-footprint switching technologies for a node featuring functional aggregation/disaggregation, together with switching in the space and wavelength domain in order to handle 1-Pb/s capacity.

Objective 4: Design and development of scalable and modular S-BVT architectures, allowing to adaptively generate multiple flows of Tb/s capacity and enabling up to 100 Tb/s aggregated capacity per link.

Objective 5: Development of scalable and modular metro network architectures for subsystem sharing and functional reuse to support flexible agile spectrum/spatial switching addressing capacities of Pb/s per node.
The PASSION project team aims at upgrading the present metro network targeting 1 Tb/s per channel and enabling up to 100 Tb/s per link thanks to flexible agile spectrum/spatial aggregation. Moreover, with respect to the present solutions based on external modulation, PASSION will demonstrate the development of suitable optical modules achieving at least a 10-fold energy reduction in consumed Joule/bit and equipment footprint reduction by more than 10. The agile generation and routing of optical channels with high-capacity will be enabled by scalable, modular, sliceable bandwidth/bitrate variable transport, enhancing system capacity and reach, also exploiting the space dimension (SDM is approached either considering different fibre cores or different fibres in a bundle).
