300+ Gbps Short-Reach Optical Communications

Abstract: We review experimental intensity modulation and direct detection demonstrations for short reach optical communications. We also evaluate 8-level PAM and DMT transmitter to deliver 300 Gbps line rate and beyond per single lane in C-band. © 2020 The Author(s)

“…Below 9 Gbit s −1 the signal is error-free. Given that a BER ≤ 4 × 10 −3 can be corrected using error correction codes without excessive overhead, [3,27] we achieved an error-free transmission up to 10 Gbit s −1 which is far beyond the state-of-theart at this wavelength in free-space using either external [28] or direct [3] modulation, without any postprocessing nor equalization.…”

“…We attribute the main implementation penalty to electrical components in the transmitter which could be remedied by improving the bandwidth and linearity in the electrical domain. Further improvement in the electrical signal generation scheme for PAM potentially would allow achieving better signal quality and, thus, improving the link latency thanks to a reduced FEC [21,31]. This would result in an even higher baud rate for multilevel signal transmission with the EML [19].…”

“…Eight optical lanes-based 400 GbE solutions are already being deployed [8,9]. Solutions based on eight optical lanes [10][11][12][13][14][15], or even four optical lanes [16][17][18][19][20][21][22][23][24][25][26][27], for 800 GbE are more appealing thanks to the use of using high bandwidth components. This allows reducing of costs, power consumption, and complexity of parallelism.…”

“…High-speed digital/analog to analog/digital converter (DAC/ADC) [8], and broadband optoelectronic components including the direct-/electro absorption-modulated lasers (DML/EML) and silicon photonics (SiP)-based modulators [9] are being reported. With advanced components and DSP, several IM/DD system demonstrations of beyond 200 Gbps lane rate have been reported [10][11][12][13][14].…”
