Single-Lane 100Gb/s 4-PAM Transmission over 80km SSMF Based on K-K scheme and Integrated 10G TOSA

We experimentally demonstrated a 10G tunable InP TOSA based 100G 4-PAM transmission over 80 km SSMF employing Kramers-Kronig receiving technologies, nonlinear compensation algorithm and partial response signaling. The required OSNR of 32.5 dB at the 7% overhead FEC limit (BER=4.×10
^-3
) was achieved.
