“…The same gains were experimentally confirmed for a variety of AIRs, which were achieved by rate-matching the independent identically distributed input binary data to the specific MB PMF. Most recently, a system was demonstrated for a transoceanic distance with a record high capacity [61]. The simplicity of the rate matcher, together with its transparency to the FEC makes it attractive for optical fiber communications.…”

“…It was demonstrated in [61,63], that pilot symbols can be used at a rate of 1-2% for both purposes. This technique also improves the tolerance to phase slips, allows for adaptive equalization, and can potentially be used for frequency and clock recovery.…”

“…Various bidimensional (2D) modulation formats with different SEs have been considered to minimize bit-error rate (BER), maximize mutual information (MI) or generalized mutual information (GMI) for a given constellation and signal-to-noise ratio (SNR) [1]. There are several ways to optimize constellations over a given channel, including geometric [2], probabilistic [3][4][5][6] and hybrid shapings [7].…”

“…Research in long-haul optical fiber communication systems is currently being driven by two complementary strategies: bandwidth expansion and spectral efficiency enhancement. For example, recent record capacity demonstrations have implemented extended bandwidth long-haul transmission using both C-and L-band EDFAs [1,2], effectively doubling the transmission bandwidth, albeit with a spectral guard band between the transmission windows. Semiconductor optical amplifiers (SOA) have also been considered for continuous-band gain in transmission systems with bandwidths up to 100 nm [3].…”

“…The simultaneous use of multiple code rates for forward error correction (FEC) has been shown to increase transmission throughput, by maximising the information rate on a per-channel basis. Recently, probabilistically (PS) [1] and geometrically shaped (GS) [4] modulation formats have also been proposed to increase the achievable information rate (AIR) for a given signal-to-noise ratio (SNR). However, signals shaped to maximize AIR in an additive white Gaussian noise channel (AWGN) typically lose the features exploited by receiver-side digital signal processing (DSP) algorithms (e.g., carrier phase estimation and equalization) and therefore require a training overhead, which in turn reduces the gains from shaping.…”
