I had an interview for an L2 Network Engineer role, and went intense 😅 Its been a long time since I revised or practice networking, any one join me in the studing journey!.
I still think about the version of me who could solve these in one sitting.
Think of OTN as: The organized traffic inside the lanes-packets with FEC, IDs, monitoring, and switching. How They Work Together OTN prepares and organizes the service DWDM transports it over optical wavelengths OTN = Digital transport DWDM = Optical highway
It encapsulates client services and provides intelligent transport functions. Key points: Encapsulation into ODU/OTU frames Supports FEC (Forward Error Correction) Performance monitoring & alarms ODUk switching & grooming Provides carrier-grade protection mechanisms
DWDM vs OTN - What's the Difference? Today I want to clarify one of the most common questions in transport networks: What is the difference between DWDM and OTN? Although both are used together in modern optical networks, each one plays a very different role.
