We estimate resource savings from low-margin optical-network design considering (i) different transmission modes (including PCS), (ii) full vs. actual load for interference modelling and (iii) greedy heuristic vs. evolutionary metaheuristic for routing. Numerical results, mimicking multi-year-traffic evolution, allow to quantify extent of these savings.

We demonstrated a transmission of 4x53 GBd PAM4 signals using a bismuth-doped fibre amplifier for the first time. Transmission reach was successfully expanded by amplifying 4 CWDM signals from 1271 to 1331 nm.

Theoretical gains of digital multi-carrier systems are hindered by the use of sub-optimal conventional phase recovery, especially after fiber transmission. We experimentally validate an advanced, dispersion-aware algorithm that addresses this issue, achieving SNR gains up to ∼0.5 dB with 800G 125 Gbaud 16-carrier PCS-64QAM, transmitted over 1800 km.

Using real-time transceivers with symbol rates up to 72 GBd, we investigate the impact of ROADM filtering on optimum symbol rate and fractional m-QAM modulation required to maximize channel capacity. Granularity below 5 GBd is shown to yield maximum margin for a given link passband.

We present a photodiode in which germanium is laterally sandwiched in between complementary in-situ doped silicon layers. We demonstrate optoelectrical 3-dB bandwidth ≥110 GHz with responsivities of 0.6 A/W at 1550 nm, and show, for the first time, results at 1310 nm wavelength.

A silicon photonics chip is successfully employed for frequency multiplication of an 18.5-GHz clock up to 92.5GHz (×5) with low additional phase noise. The chip includes a 20-GHz phase modulator for comb generation and a thermally tunable distributed feedback resonator for reconfigurable spectral mode selection.

We report a converged fixed wireless testbed spanning Metro-Access, built with no dedicated or mobile technology. An overarching intelligent orchestrator is implemented to tailor, in real-time, the fixed-line end-to-end QoS-aware bandwidth slices to the wireless system, taking into account the status of the entire network.
