Coherent Detection vs. Direct Detection
Scales to 400 Gb/s for metro and regional applications
Enables 100G transport over ultra-long-haul distances without costly regeneration
or Raman amplification
Provides improved system margin in metro applications for increased capacity
Carries multiple 100G services over a single 50GHz channel significantly
improving metro and regional transport economics
Delivers up to 30% capacity improvement in flexible grid environments 5.
