Digital coherent transceivers: From algorithm design to economics

• Who is the actual customer for the DSP? • How much is the customer willing to pay for a 1dB better reach? • Can the operator use the new DSP on his installed base? • What's the value of a lower power consumption? • Can the operator use the full flexibility of a chip with various modulation schemes and line rates? • How many different DSP designs does the segmented market need? • How much does the development cost and what are the part costs in production?
