In 6500 optical platform, how long we can carry 100G transponder signal without 3R functionality of DWDM.
There are some very long Terrestrial networks that have been built without the need for 3R. One that comes to mind is Telstra debut Ciena low-latency optical technology 10,000+ km Round Trip. The length you can go without the need for 3R has many factors such as span length, fiber losses, PMD/CD, Fiber Type, Spectrum fill, amplification technologies, etc. By plugging this information into Ciena's optical modeler OnePlanner you can determine if and where you need to place Regeneration nodes within your network. I would highly recommend working with your Sales Engineer to build and validate your optical network plan.
Hey NAVDEEP, did Darcy's response help address your question? Let us know if you have any follow up questions or have an update to share, we look forward to hearing from you.
Thanks for reply, I was searching for some more information regarding Terrestrial networks transmission without 3R.
Can you provide any relevant document for that?
I'd start with reviewing the Photonic Layer Guide (NTRN15DA) that is part of the 6500 planning documentation series. As indicated, there are a lot of variables that affect the requirement and or placement of 3R nodes within a network. Optical modeling tools such as One Planner are your best way of determining if and where this 3R needs to take place. Workign with your Ciena Sales/Solutions Engineer is your best option to ensure that you get a network that meets your needs.
