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

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
Colorless Directionless Add/ Drop Ports – Any Wavelength Any Direction

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
Improves Flexibility while increasing the capacity of the photonic line
