“…Filterless solutions have been proposed for terrestrial and submarine network topologies. The first studies were focused on regional and core network applications [6][7][8][9][10]. Unsurprisingly, comparative cost analyses in terrestrial networks have shown significant savings are achievable in the filterless network solutions due to replacement of switching and filtering elements by simple fiber couplers.…”

“…A validation of the physical layer performance of passive filterless networks was carried out in [6], while a control plane solution based on path computation element (PCE) was presented in [7]. The dynamic operation of filterless network supported by the proposed control plane was evaluated in [8], indicating similar trends in the resource usage overhead as in the static scenario [5]. Resilience issues were addressed in [9] by constructing the optical fiber trees so as to guarantee for at least two linkdisjoint paths between each pair of nodes in the network.…”

In Elastic Optical Networks (EONs), advanced transmission techniques based on coherent detection strategies have been proposed and exploited to provide high flexibility in resource allocation. So far, these techniques have assumed the constraint of each optical signal being transmitted along a dedicated frequency slot, by carefully avoiding frequency overlap with other optical signals.In this study, an overlap technique, that enables uncorrelated optical signals to be superimposed along the same spectrum resources, is designed and validated through simulations, both in terms of performance bounds and bit-error rate (BER) in coded transmissions. In particular, it is demonstrated how this technique allows each overlapped signal to be correctly received and detected. The proposed technique is less spectrally efficient and more complex to implement than increasing the constellation size and using non overlapping frequency slots, but it warrants consideration for flexible networking.The proposed technique is first theoretically detailed and justified. Then, networking scenarios and implementation schemes suitable for its effective utilization are identified and applied in the case of two overlapped 112 Gb/s polarization-multiplexed quadrature phase shift keying (PM-QPSK) signals. Simulation results show that, applying 3-dB optical signal-to-noise ratio margin on the achieved bounds, optical reaches of around 800 km can be successfully supported by the proposed overlap technique.
