“…In the near future, the need for 400G connectivity and beyond has been crystal clear for intradatacenter networks [2,3]. Intra-datacenter interconnects (DCIs) comprise server-to-ToR (top of rack), ToR-to-fabric, and inter-fabric links, covering links with transmission distances from tens of meters to several kilometers [4].To address the growing capacity demands in DCIs, research efforts have been put on improving the single lane rate, e.g., to 100 Gbps and beyond with intensity modulation and direct detection (IM/DD) systems [5][6][7][8][9]. In addition, low latency should be guaranteed for time-critical services involving DCNs (e.g., remote control), and therefore heavy digital signal processing (DSP) needs to be avoided.…”

A BiCMOS chip-based real-time intensity modulation/direct detection spatial division multiplexing system is experimentally demonstrated for both optical interconnects. 100 Gbps/λ/core electrical duobinary (EDB) transmission over 1 km 7-core multicore fiber (MCF) is carried out, achieving KP4 forward error correction (FEC) limit (BER < 2E-4). Using optical dispersion compensation, 7 × 100 Gbps/λ/core transmission of both non-return-to-zero (NRZ) and EDB signals over 10 km MCF transmission is achieved with BER lower than 7% overhead hard-decision FEC limit (BER < 3.8E-3). The integrated low complexity transceiver IC and analog signal processing approach make such a system highly attractive for the high-speed intra-datacenter interconnects.

“…100 Gb/s transmissions were experimentally demonstrated employing short-wavelength VCSELs and multimode fibers (MMF), together with advanced modulation formats, such as pulse amplitude modulation (PAM), discrete multitone (DMT), or carrier-less amplitude and phase modulation (CAP) [1][2][3]. However, the bandwidth of MMF prohibits a sufficiently long transmission distance, restraining the transmission reach to a few hundred meters.…”

“…With extremely low complex transceiver design, especially when the communications are achievable with analog equalization, real-time communication can be realized [4]. Many research efforts have been also put on advanced modulation formats, such as 4-level pulse amplitude modulation (PAM4) [5] and discrete multi-tone (DMT) [6] to support high-speed single lane transmission with relaxed requirement on the system bandwidth. For DCN applications for which distances of more than a few kilometres are required, recent works on high data rate advanced modulation signals transmission with 1.5-μm single mode vertical cavity surface emitting laser (VCSEL) and single mode fiber (SMF) [6] also shows promising results to match the requirement on cost, energy consumption, footprint, and potential for seamlessly extension to long-term parallelism enabled by SDM techniques.…”

Emerging mobile and cloud applications drive everincreasing capacity demands, particularly for short-reach optical communications, where low-cost and low-power solutions are highly required. Spatial division multiplexing (SDM) techniques provide a promising way to scale up the lane count per fiber, while reducing the number of fiber connections and patch cords, and hence simplifying cabling complexity. This talk will address challenges on both system and network levels, and report our recent development on SDM techniques for optical data center networks.
