Powered by the ADVA FSP 3000 open line system, spectrum as a service is a whole new way for communication service providers (CSPs) to drive more revenue from their already deployed fiber networks. CSPs can now sell different frequency blocks to different customers, enabling them to fully harness the untapped value in their networks.

1. Introducing spectrum as a service
March 2020
A new way to monetize optical network infrastructure

End customers need more capacity and flexibility
• Growing traffic demands are exceeding single wavelengths
• Institutions are looking for increased flexibility and
control to better deal with continuous change
Paving the way for a new service offering
Ever-increasing capacity demand
CSP and carriers must respond
• They need to provide new differentiated services with
maximum reuse of their existing network infrastructure

Market demands and technology go hand-in-hand
Optical networking technologies are also evolving
Coherent transport innovation
• Coherent technology increases spectral efficiency, and simplifies
planning and operation
• Ultra-flexible interfaces and adaptive networking optimize
performance
Flexgrid technology innovation
• Programmable flexgrid technology with finest grid
granularity is becoming affordable
• This enables new types of optical VPN services

 Accommodates different lifecycles
 Enables greater flexibility for varying network optimization requirements
 Facilitates multi-vendor environments; no implementation lock-ins
 Provides open orchestration and control
Unlocks innovation and enables best-in-breed solutions
A new era of openness and disaggregation
Disaggregation benefits:

Traditional options for high-bandwidth services
Dark fiber service
• CSP offers fiber only
• End user owns and operates the network
• Provides high level of flexibility and user control
Fiber
OLS
Terminal Terminal
Active wavelength service
• CSP owns and operates the network
• End user purchases fiber capacity in wavelength increments
• Provides low level of flexibility but less operational overhead

Combining the best of dark fiber and
active wavelength services with
multiple benefits for CSPs and users
Unlocking the network’s full potential with a new class of wholesale services
Spectrum as a service – the sweet spot

• Optical spectrum is segmented into slices
• Slices can be assigned to different users
and applications
• CSPs and carriers can sell unused spectrum
• CSPs can provide fully assured spectrum
services and complete control
Monetize unused spectrum and provide differentiated services
Spectrum as a service – What does it mean?

A truly open line system with open control and management is key
Spectrum as a service – the building blocks
Programmable flexgrid technology
Gridless spectrum allocation
Support for any coherent format and baud rate
Service demarcation and monitoring
Optical spectrum policing
Strict user separation
Open optical line system
Truly open and disaggregated OLS design
Full OLS characterization (GOSNR)
Open control and management
Programmability with open APIs
Network slicing with client control

Passband
Modulation
Baud rate
• High-resolution flexgrid OLS enables the
optimum support of high coherent
modulation formats with high baud rates
• By controlling baud rate and coherent
modulation format, end users have control
• Optimizing bandwidth-distance trade-off
• Optimizing capacity-margin trade-off
… and CSPs offer differentiated services
Spectrum service users can leverage their own terminals to optimize throughput
Spectrum as a service – putting the user in control
