A series of high-capacity optical transmission system experiments at 1.3 ¿m wavelength are reported. Margins greater than 2 dB were observed at 144 Mbit/s over 93 km and at 750 Mbit/s over 65 km, thus demonstrating the practicality of unrepeatered optical systems using commercially available components.
