AB  - In this work, we propose to use four-level pulse amplitude modulation (PAM4) and multicore fibers (MCFs) to support very high capacity datacenter interconnect (DCI) links. The limitations
imposed by inter-core crosstalk (ICXT) on the performance of 112 Gb/s up to 80 km-long optically
amplified PAM4 inter-DCI links with intensity-modulation and direct-detection and full chromatic
dispersion compensation in the optical domain are analyzed through numerical simulation for high
and low skew-symbol rate product (SSRP). With only one interfering core, we show that those
PAM4 inter-DCI links achieve an outage probability (OP) of 10−4 with a maximum ICXT level of
−13.9 dB for high SSRP and require an ICXT level reduction of about 8.1 dB to achieve the same OP
for low SSRP. Due to using full dispersion compensation, for an OP of 10−4, the maximum acceptable ICXT level shows only a 1.4 dB variation with the MCF length increase from 10 km to 80 km. When
considering the ICXT induced by several interfering cores, the maximum ICXT level per interfering
core for an OP of 10−4 decreases around 3 dB when doubling the number of interfering cores. This
conclusion holds for high and low SSRP regimes. For two interfering cores, we show that a single
interfering core with low SSRP is enough to induce a severe reduction of the maximum acceptable
ICXT level.
