General Concept: HD-FEC and SD-FEC
 Hard-decision decoding
• Decoding using a fixed decision threshold
• Low cost and low complexity, widely used in the 2.5G, 10G and 40G etc. non-coherent systems
 Soft-decision decoding
• Decoding using a decision threshold and multiple confidence thresholds
• Better performance than hard-decision but complex processing


Allocate coherent wavelengths to
long-wavelength sections first.

Optimize and adjust noncoherent wavelengths to shortwavelength sections.
Migrate 10G/2.5G wavelengths

Migrate services carried on
2.5G/10G wavelengths to the
client side of new coherent
wavelengths for improving the
wavelength usage.
