Article Excerpt:
Feature: 100 Gig and Beyond. Part 2
  • Xtera's Raman amplification boosts capacity and reach
  • 40 Terabit optical transmission over 1,500km in Verizon trial
  • 64 Terabit over 1,500km in 2015 using a Raman module operating over 100nm of spectrum  

 

Herve Fevrier
Optical transport equipment makers continue to research techniques to increase the data carried long distances over a fibre without sacrificing reach. The techniques include signal processing of the transmit signal to cram data-carrying channels closer in the C-band, advanced soft-decision forward error correction (SD-FEC) and receiver signal processing to counter transmission impairments.
