Transport Generic Requirements
• Support Residential, Enterprise/Government, Wholesale, And Internal Requirements
• Remain “X”able– Accessible (Protocol Agnostic, Defined Interfaces) – Predictable (Throughput, Latency, ...)– Scalable (Rate Adaptive/Adjustable Port) – Reliable/Survivable (Protected – Nodal, Port, Link,
Route, Service, …)
• Become Dynamic– Control Plane Enabled– Topology, Element And Capacity Aware– Routing, Bandwidth Allocation, And
Protection/Restoration Functional
© Verizon 2007 – All Rights Reserved21
Future Optical Network Requirements
• More Capacity (Speed and Wavelengths)• Greater End User Access Bandwidth• Common Control Standards• Easier Fiber Administration In Central Office And
Outside Plant• Fiber In the Premises for Higher Bandwidth and Ease
of Installation• Higher Functional Integration (To Reduce Cost)• Bandwidth On Demand Capability• Multi-Vendor Supply• Maintenance Of Reach And ITU Spacing At Higher
Speeds• Routing Flexibility
© Verizon 2007 – All Rights Reserved22
Optical Innovation Areas
• Beyond GPON: 10GPON And/Or WDM PON• Low Loss/Bend Insensitive Fibers • Mechanized Optical Patch Panels For Central Office,
CEV And FDH Applications • GMPLS Control Plane Standards For SONET And
DWDM• More Wavelengths Per Fiber• Higher Bit Rates: 40G/100G• Alien Wavelength• Advanced Modulation Techniques For 40/100 Gbps • Dynamic Colorless Mesh Networking• Optical Packet Switching
