Optical Networking / DWDM Basics (Dense Wave Division Multiplexing)

Optical networking delivers the distance, bandwidth scalability, resiliency, and manageability that broadband networks require.
Slides are available here ribboncommunications.com/comp...
You're invited to a special session from Ribbon on Tuesday, December 15th where we will review optical networking technology and basics and explain how optical networks solve reachability, survivability, bandwidth growth, and maintenance challenges for broadband services.
Key topics of discussion:
What problems do optical networks solve? What are the major piece parts and important vocabulary? What do I have to think about when deploying? Any cool stuff on the market I should be aware of?

i think this is the best DWDM presentation i have ever seen so far. sincere congrats

[@L33TDOT3R]

great video about DWDM technology
i'm working a lot with your equipment(SDM, XDM, Apollo OPT) and nice to see that u have this very informative presentation for my colleagues

[@foxxrider250r]

This just blew my mind

[@awanishsingh123]

Nice and very useful presentation on DWDM

[@Derbauer]

This is so fascinating, even though as not in this industry a lot of it is going over my head 😀😁

[@muddasirkhan805]

great talk! i wish more people were talking to network engineers about optical, as more and more network engineers are expected to know the ins and outs of dwdm

[@PiyushSharma-gi6vi]

a good brief video for DWDM systems. A few points on protection :
- MOTR (transponder) module can itself provide protection using integrated OPS. (at the expense of having another line port redundant)
- Trunk OPS can be deployed in photonics where the OPS card makes switching decisions solely on the Rx power.
- Client OPS can used in MUX , where an external OPS card can provide redundancy between clients(100GE or OTU4) either in same transponder shelf or different transponder shelf.
- We can have mesh protection in photonics layer, of course software defined routing is there using photonics control plane. intended protection routes or a combination of routes between originating and terminating sites can also be decided beforehand.
- The L0CP mesh restoration is rather slow ( since it finds & creates new path depending upon N number of factors , like spectrum availability in possible paths, any potential alarms in those paths as well )
- OTN switching to have

Thank you

[@RibbonCommunications]

You're welcome

[@prafful_kumar1988]

@@RibbonCommunications why there are amplifier as EDFA-SDH, EDFA-DWDM etc.
Are they designed specific network.
Can we use EDFA-SDH in DWDM system?

[@Arun-zd5lp]

can i get the slides pls

[@abuhanif592]

great one sir.
would you suggest me some topic on basis of dwdm which we can work for future (for research )?

[@md.rakiburrahman1397]

Hi, like you I also would like to do research on DWDM/ OTN. Where are you from. Let's do it together

[@tariqehsan6000]

Thanks very informative session. Could you please share the slides if possible. thanks

Hi! my name is Gilbert i'm from Brazil and i'm need help about module WSS in to ROADM, explanation, can you help me about that? I could use your intelligence for solution this?
