Closed Optical Transport
Disaggregation in Optical Transport Networks will deliver the next-level of efficiency and break vendor lock-in.
Optical solutions are traditionally provided as closed solutions. The transponders and optical line system are highly coupled. The optical line system can only transport wavelengths from the same vendor.
In this traditional closed optical networking solutions, the entire solution is provided by a single vendor, hence operators are dependent on the vendor’s roadmap and limited to a single source of innovation. This model limits functionality, service offerings, and results in higher costs.
Disaggregated Optical Transport
Disaggregated Optical Network decouples the optical line system from optical transponders. Optical line systems have an average lifecycle of 10 years. On the contrary coherent DWDM transponders are constantly evolving; on average every 2 years. Therefore decoupling them enables operators to expand their network at any time, taking advantage of the best of breed and most cost-efficient technology.
Operators can leverage their existing optical line system and choose the best available transponders from any vendor to meet their specific needs for their metro or long-haul networks.
On the management side, Open optical networks leverage standards-based management interfaces and data models including YANG, NETCONF, and RESTCONF making it easier to automate planning, service provisioning, and troubleshooting.
Open and disaggregated optical networks help service providers remove vendor lock-in, lower TCO, and ignite faster innovation.
