Agenda
Optical Network Evolution to Tunability Applications of Tunable Lasers in the Network Benefits of Tunability in the Optical Networks
• Service providers deployment business case OIF MSA Founders
• iolon, Intel, Santur and Bookham• Gaining momentum …
MSA scope and objectives
Revolutions in Fiber Optics – 1980s
• Single , point-point links • Single-mode Fiber• InP Lasers
Networks Enabling Technologies
Enabled lower transmission cost
Revolutions in Fiber Optics – 1990s
Networks Enabling Technologies
• WDM point-to-point links • EDFA• DFB Lasers• Optical Pump Lasers
Increased capacity to reduce total network cost
Revolutions in Fiber Optics – Today
Networks Enabling Technologies
• Re-configurable Networks • Tunable Lasers• Tunable Filters• Photonic Switching
Reduce both Capital and Operational expenses and increase network flexibility
Why Tunable Devices?
Current DWDM networks are static since unique laser required for each wavelength• Provisioning is a local, manual process• Expensive, takes weeks
Tunable devices enable dynamic DWDM networks• Flexible, remote service provisioning under
software control • Cost savings to carriers by reducing inventory,
provisioning and the wavelength contention costs• New revenue generating services to carriers for
rapidly provisioned services Tunable lasers have become the “Holy Grail”
for next generation DWDM networks
Tunable Lasers Have Arrived! Tunable lasers, under development for over a decade, have only
recently met the basic optical performance requirements• New developments have allowed tunable lasers to approach
performance levels of fixed lasers• Maturation of new technologies• Integration of multiple technologies
Tunable lasers use a variety of structures and tuning methods• Thermally tuned DFBs – single element - narrow thermal tuning• Integrated DFB Array –integrated combiner- temperature tuned• Switched DFB Array- MEMS switched - temperature tuned• DBRs – Distributed Bragg Reflector chips – current tuned• SGDBRs – Sampled Grating DBRs – current tuned• VCSELs – Vertical Cavity Surface Emitting Lasers – MEMS tuning• ECLs – External Cavity Lasers – mechanically tuned
Tunable Interface Networking Requirements
Better or same optical performance as the fixed wavelength DFB’s• Output Power, Linewidth, RIN, SMSR
Reliability• Meet requirements to support 99.999 network
reliability• 100% Locking• Hitless Tuning
Density• Small form/factor• Low power consumption
Revenue Generating services• Remote Provisioning and Bandwidth on demand• Efficient network utilization
Price• Same price as fixed wavelength DFB’s
Network Applications Sparing /Inventory Mgmt
• Back-up laser that can replace any faulty laser in system Universal Line Card / Transponder
• Save inventory and production costs by designing “universal line card”
These applications reduce cost of operation of networks for Service
Providers while enabling new revenue opportunities

Management
Fast Provisioning Wavelength Conversion Flexible OADM/OS Protection/Restoration Bandwidth on Demand
Benefits:• Rapid service turn-up with ability to rapidly handle churn
– Maximum flexibility with limited pre-deployment of capital
• Highest network availability with additional photonic layer restoration capability
• Simplified network operations and significant OPEX savings
• Lowest deployed capital cost
• Enables photonic flexibility, thereby reducing EXC core size requirements
Example of Agile Transparent Networks
4. Photonic Layer Control Plane•Auto-Discovery of network topology and photonic
properties•Automated wavelength routing, engineering &
activation•Wavelength assignment “on demand”
1.Transparent Photonic Switch• All optical by-pass eliminates OEO costs on express traffic
3. Tunable Edge• Full Spectrum Tunable Transponders &
Filters• Enables instantaneous any-to-any
connectivity
2. Dynamic Line System• Per- control to enable dynamic wavelength assignment

Capex and Opex Savings
If demand set is known exactly, static transparency can produce lower
network cost. In reality, to handle traffic variations, network price is more than
doubled with static technology.
