ERMES proposes a disruptive approach to the colourless ONU transmitter for the Next Generation Access Network (NGAN) Wavelength Division Multiplexed Passive Optical Networks (WDM PON).

The breakthrough idea is to use a significant portion of the network to implement an embedded self-tuning modulable laser cavity sustained by a dedicated multifunction active device (MFAC).

The specific scientific and technical objectives of the ERMES project leading to the achievement of its main goal are the following:

1. Development of a suitable active chip component able to sustain the triple role requested to this MFAC device;

2. Theoretical understanding and development of a simulation model of the MFAC and of the network-embedded cavity (long laser cavity) for operation up to 10 Gb/s;

3. Realization of a laboratory prototype operating at 10 Gb/s;

4. In-field demonstration of the colourless prototype operating at 10 Gb/s.


The prototype of a colourless WDM PON ONU is a potential highly effective alternative to the existing approaches in terms of cost reduction as it is colourless and gets rid of the need for external seeding sources. It is also appealing in terms of achievable performance, as it is not impaired by Rayleigh back-scattering, allowing for longer bridged distances. ERMES target data rate is envisaged to fulfil the requirements for the next generation access network, which will be essential to support the development of broadband applications and services. ERMES success will enforce European industrial leadership in the access arena, whose development in terms of capillarity and bandwidth has major social and economical fallouts. In a broader sense thus, ERMES will have a societal impact by contributing to support the data traffics needed for new applications for activities such as education, sustainable health and e-government.
