“…Their theoretically obtained results are confirmed through experiments that demonstrate successful 40 Gbit/s wavelength conversion functionality for NRZ data signals only when a differentially biased SOA-MZI configuration is employed, whereas an error floor is obtained when 40 Gbit/s NRZ all-optical wavelength conversion with the standard single-control SOA-MZI scheme is attempted [4].

We highlight the feasibility of experimental implementation of both inverted and noninverted wavelength conversion, 2R regeneration, and all-optical logic functions, such as OR, NOR, XOR, and XNOR optical gates by exploiting the self-polarization rotation in a semiconductor optical amplifier (SOA) device without changing the setup configuration. Switching between each optical function is done by only adjusting the input optical power level. In order to allow optimum control and preserve the polarization state of the injected and collected signals, the polarimetric measures have been carried out in free space.

Gridless optical networking field trial: flexible spectrum switching, defragmentation and transport of 10G/40G/100G/555G over 620-km field fiber

Abstract:We present results from the first gridless networking field trial with flexible spectrum switching nodes and 620 km of installed fibre links. Signals at 10G, 12.25G, 42.7G, DP-QPSK 40G, DP-QPSK 100G and 555G are generated, successfully transported and switched using flexible, custom spectrum allocation per channel. Spectrum defragmentation is demonstrated using integrated SOA-MZI wavelength converters. Results show error-free end-to-end performance (BER<1e-9) for the OOK channels and good pre-FEC BER performance with sufficient margin to FEC limit for the 40G and 100G coherent channels as well as for the 555G super-channel.

“…However, full-range wavelength tunability results in very complex, power-consuming and lossy WC devices [26][27][28]. Indeed, current techniques to achieve conversion between any given combination of input/output wavelengths involve cascading a set of limited range WCs, thereby leading to very expensive devices [29].…”

Abstract-Translucent optical networks have emerged as potential yet feasible candidates to bridge the gap between the opaque and transparent network architectures. By allowing electrical 3R signal regeneration only at selected points in the network, translucent architectures represent a cost-effective, power-efficient solution. Concurrently, forecasts predicting highly dynamic traffic patterns make it crucial for next-generation transport networks to engage highly agile technologies that include sub-wavelength switching (SWS). In translucent SWS networks, contention resolution is achieved through the still technologically immature all-optical wavelength converters (WCs). Since WCs are expected to be expensive, power-consuming devices, there has been significant research effort on devising WC-sharing architectures, which aim at minimizing the number of these devices in the network. WC sharing, however, requires complex switching fabrics that involve a much higher number of optical gates and stronger degradation due to physical layer impairments (more electrical 3R regenerators). It is clear, then, that the technological interest in WC-sharing architectures mainly depends on the cost trade-offs existing between these three components. For this reason, in this work, we carry out a comprehensive cost feasibility analysis of translucent networks based on asynchronous WC-sharing packet switches. After modeling a set of translucent WC-sharing switching fabrics, we assess their performance in an isolated node scenario in terms of the number of WCs and optical gates required. Given the results obtained, we select the shared-per-node (SPN) architecture to compare its hardware requirements with those of a network based on dedicated WC nodes (i.e., one WC per wavelength and input port). To this end, an iterative simulation algorithm is used to dimension translucent SWS networks considering a broad range of continental-scale topologies. The results are first analyzed using relative cost values, and finally the viability/feasibility of WC-sharing schemes is discussed considering state-of-the-art technology. Our main conclusion is that, for SPN-based architectures to become cost effective, the cost of WCs has to be at least two orders of magnitude higher than that of the optical gate and similar to or lower than that of the electrical 3R regenerator.
