Long-haul terabit transmission (2272km) employing digitally pre-distorted quad-carrier PM-16QAM super-channel

We experimentally demonstrate long-haul WDM transmission of 36GBaud four-subcarrier Terabit PM-16QAM super-channel. Digital pre-distortion enables ~50% reach improvement for both LAPSCF and SSMF fiber-types, with maximum recorded reach of 2272km and 949km, respectively.
