Agile Open Line System

1. What is an Agile Open Line System?

2. What is Required for an Agile Open Line System To Exist?

3. What does an Agile Open Line System Enable?



INSTRUCTION

What is an Agile Open Line System?

A Fully Reconfigurable, Coherent Optimized, Line System which can carry any wavelength service regardless of modulation format, data rate, or vendor and allows for these wavelength services to be created / modified programmatically.

• Colorless, Directionless Wavelength Routing

• Colorless, Directionless Wavelength A/D

• Hybrid (Raman + Switched Gain EDFA) Amplifiers

• Flexible Grid Support

• Advanced Monitoring Capabilities

• Alien Wavelength Management

• Programmable, open interfaces

Decouple the Transponders from the Transport System



INSTRUCTION

From Fixed OADM to Fully Reconfigurable ROADMFixed Terminal Architecture

State of the Art DWDM System in 1999!

Completely Closed System

• No Reconfigurability (Point to Point Only)

• No Alien Wavelength Support

• Static Mux / Demux Structure

• Transponders were Wavelength Specific

• No Software Defined NetworkingAlcatel 1640

Agile Photonic Layer:

• Enables dynamic traffic creation with minimum deployed resources

• Existing transponders can be used to transmit/regenerate/recolor any wavelength to/from any direction without recabling.

• Enables Photonic Restoration

INSTRUCTION

Flexible Grid

•50G

Flexible Grid is the ability to set channel spacing to an arbitrary grid (e.g. 37.5GHz, or 50GHz, or 62.5GHz, etc) instead of the standard 50GHz or 100GHz.

1. Higher channel count within the same amplifier BW window

2. Spectral efficiency tradeoff for reach vs capacity

3. Grouping of multiple carriers within a larger channel for easier management

4. Allows support for higher baud-rate transmission
