This paper extends a recent demonstration of a 2-line side 15-mode spatial division multiplexing network node. The node is based on fifteen 2 × 2 wavelength cross-connects (WXCs) to direct up to s…
We investigate recirculating transmission of a wideband S-, C- and L-band signal in a 4-core fiber. We transmit 552 x 25 GHz spaced, 24.5 GBd channels, covering more than 120 nm bandwidth from 1487…
Few-mode fibers and coupled-core multi-core fibers are attractive transmission media for space-division multiplexed transmission systems as they enable a high spatial channel multiplicity whilst su…
We introduce a flexible, software-defined real-time multi-modulation format receiver implemented on an off-the-shelf general-purpose graphics processing unit (GPU). The flexible receiver is able to…
High capacity transmission with a data rate over 10.66 Pb/s is demonstrated in a 13 km, 38-core-3-mode few-mode multi-core fiber. This was achieved with a single optical comb source to generate 368…
We investigate high-throughput, multi-band transmission in a 4-core multi-core fiber (MCF) with the same 125 μm cladding diameter of standard single-mode fiber (SMF). A single wideband comb source…
High-capacity, long-haul transmission over a coupled-core three-core multi-core fiber is investigated in a recirculating loop experiment. We report key system characteristics, such as the optimum l…
We demonstrate the first continuous variable quantum key distribution (CV-QKD) system with fully digital phase and polarization tracking, enabling the first wavelength division multiplexing experim…
