Compact but Precise. NEC keeps its journey through inovation intact

NEC Corporation (TSE: 6701) and its subsidiary OCC Corporation announced on 15th January 2020 that they have completed full qualification of subsea repeaters and optical cable containing up to 20 fiber pairs (40 fibers).

Industry impact of this innovation is as below:

  1. This is more than 100% improvement in fiber count over traditional fiber pair systems previously built by NEC.
  2. Cable owners worldwide would be able to construct subsea telecom cables capable of the highest traffic capacity, while optimizing the cost per bit of the wet plant for this development.
  3. NEC can visually identify individual fibers using a combination of ring marking and conventional fiber coloring. This allows the potential number of fibers in a cable to be greatly expanded. Significantly, in OCC cable, the fiber’s transmission performance is completely unaffected, either by the fiber coloring or cabling processes.
