Interoperability Demonstration of P1V1-2C2 Application Code

for 120 km (2400 ps/nm)

OFC/NFOEC 2006March 7-9, 2006

Anaheim, CA

Participating Companies: Azna LLCEssexKodeos CommunicationsOpnextVitesse

Impact of 120 km ITU application

• The Problem:– 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

• The Solution: Alternate Modulation Schemes – 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
