  Ultra-wideband, field-deployed metropolitan fibre transmission is
experimentally demonstrated, measuring a record 202.3 Tb/s GMI and 189.5 Tb/s
after decoding with 20.9 dBm launch power and lumped amplification only. An
experimentally-optimised 5 dB pre-tilt over the 15.6 THz optical bandwidth was
applied to overcome ISRS.
