First design of dynamically reconfigurable broadband photonic access networks (BB Photonics)

The BB Photonics develops reconfigurable access networks for providing the user with congestion-free access to virtually unlimited bandwidth. First design of reconfigurable access network architecture is presented in this paper together with preliminary specifications for components and modules. The simulation results of a reference network with wavelength agnostic optical network units based on a reflective semiconductor optical amplifier (RSOA) and a wavelength router based on ring resonators filtering characteristics give an encouraging perspective for further research. Consideration is given to a possible migration scenario

1.25-Gb/s transmission over an access network link with tunable OADM and a reflective SOA

The emerging broadband services and the avalanche-like growth of the broadband subscribers result in the intensification of data traffic in access networks. This drives the development of last-mile technologies to support multiservice provision on high bit-rate-capable reconfigurable networks. In this letter, we present the first transmission experiments carried out on the testbed of a hybrid wavelength-division-multiplexing/time- division-multiplexing access network based on cost-efficient elements like an integrated optical add-drop multiplexer and a reflective semiconductor optical amplifier. We successfully transmit two 1.25-Gb/s wavelength channels over 26-km standard single-mode fiber carrying data to and from the user

1.25 - 10 Gbit/s reconfigurable access network architecture

In this paper we propose a novel reconfigurable access network architecture which enables the bidirectional transmission of 1.25 - 2.5 Gbit/s. Optical network units (ONUs) are equipped with a reflective semiconductor optical amplifier (RSOA) and remote nodes (RNs) are based on microring resonators - both contribute to network transparency and flexibility. We also propose ONU upgrade to serve 10 Gbit/s per end-user. Next to the theoretical description and transmission simulations some principle measurement results are presented which show the feasibility of the concept
