NEC and Corning achieve petabit optical transmission

86758256_816cadb0db

Researchers from the NEC Labs in Princeton, NJ, USA, and from Corning’s Sullivan Park Research Center in Corning, NY, successfully demonstrated ultra-high speed transmission with a capacity of 1.05 petabit/s (1015 bits per second) over novel multi-core fiber that contains 12 single-mode and two few-mode cores by employing the advanced space division multiplexing scheme and optical multiple-input multiple-output signal processing technique.

The fiber designed by Corning researchers has cores arranged in a triangular lattice, which enables transmission over a large number of spatial modes. By combining spectral multiplexing with polarization and spatial mode multiplexing and employing multilevel modulation formats, NEC researchers achieved the total spectral efficiency of 109 bits/sec/Hz, while the aggregate transmission capacity was 1.050 Petabit/s, which the partners claim is the highest capacity over a single optical fiber reported so far.

Wowsers!
