“…The red ring marker in Fig. 5 corresponds to the achieved received power at the FEC threshold after 2 km of SSMF for a 56 GBd 4PAM signal reported in 4 . It offers 4.4 dB higher sensitivity compared to the split-carrier reported here.…”

“…To realise this, reduction of P mod,loss has been demonstrated using direct modulation, but requires nonlinear Volterra equalisation 2,3 . Alternatively, externally modulated lasers have enabled receiver sensitivities as low as −7.1 dBm at a BER of 3.8 × 10 −3 , but typically incur a 10 dB modulation loss 4 . Nyquist-shaped subcarrier modulation (N-SCM) has also been proposed 5,6 , using 16-ary quadrature amplitude modulation (16-QAM) to achieve 112 Gb/s at 28 GBaud per channel.…”

“…We have studied how to adapt direct-detection-PAM format (experimentally shown for 112Gbit/s-4-PAM links very recently [18]) to this architecture by means of computer simulation. More precisely, we have set several simulation scenarios, taking into account five adjacent WDM channels.…”

We compare by numerical simulation several options to increase up to 112 Gbit/s the bit rate used for intradata-center interconnections relying on the recently proposed Passive Optical Pod Interconnect (POPI) architecture, itself derived from the TWIN (Time-Wavelength-Interleaved Network) concept. The motivation for such bit rate is the need to migrate full server content in a small energy-source-aware data center. The analysis focuses on Pulse Amplitude Modulation (4 or 8 PAM), due to its performance/cost ratio. Three types of receivers are considered including a PIN photodiode with integrated semiconductor optical pre-amplifier (SOA-PIN), associated with pre-distortion mechanism. Depending on modulation format and receiver type, the maximum number of connected entities, N, (servers or racks) is limited either by the insertion losses or by the number of channels that can be packed into the band of the fast-tunable-POPI emitters. The highest N value, 48, is obtained using 8 PAM and SOA-PIN in conjunction with a 62.5 GHz grid.

“…he third generation 400 Gbps client-side links are demanding a solution as the cloud services together with the huge size datasets are driving demand for bandwidth in datacenters [1], [2]. Potential solutions are under discussion within the IEEE P802.3bs 400 Gigabit Ethernet (GbE) Task Force [3].…”

“…One attractive solution is based on eight optical lanes (i.e., 8×50 Gbps/λ [4]) thanks to compatibility with existing building blocks for 100 GbE (drivers, lasers, and photodetectors with transimpedance amplifiers). However, large lane count increases complexity and power consumption resulting in higher costs [1]. More scalable and cost efficient approach is to reduce number of lanes and increase the bandwidth for a single lane.…”
