The Problem:
–
–
–
–
•
The Solution: Alternate Modulation Schemes
–
–
•
•
Most point-to-point 2.5 Gbps links are < 120km
Market demands 2.5 Gb/s to 10 Gb/s upgrade
NRZ requires dispersion compensation
Carriers require solution with low upfront cost
No dispersion compensation needed up to 120 km
New standard defined by P1V1-2C2 application code
OIF Interoperability demo supports standard
Interoperability allows market wide adoption
