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

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.
