Amplifier at Mux or at transmitter is called Booster amplifier which amplifies the signal before it leaves Amplifier at DeMux or at receiver is called Pre amplifier which amplifies before it handover to de-mux Line amplifier is recommended when the fiber travel the distance of 100-150 km, instead of Line amplifier we can use OADM which also allow us to add or drop channel at some distance
Great video! Gives an overview of a DWDM Network creation. Just to Add On we too have CWDM [Coarse wavelength division multiplexing] where wavelengths are spread far apart. Typically used for short-range communications.
This is very excellent demo animation in very plain language really appreciated, and please add same scenario on OTN if possible and would like to thank you in advance sir !
The idea behind this channel, to learn technology with animation (not with images), so everyone can easily understand, clear the concept, and can creak the interview. For suggestion and feedback, please feel free to write in the comment section. If you like my work please like and subscribe to the channel for more videos.
Very good knowledgeable video and useful but why you use artificial voice use your natural voice bro you are doing great work you have to proud yourself. RESPECT
Explanation of DWDM Network flow is wrong(8:15). With Mux/Demux we cannot add/drop & express the channels, even if it is 2-Degree. Mux/Demux can only perform multiplexing (Many to one - Nx1) & demultiplexing (one to many 1xN). For add, drop & express functionalities we have to use OADMs (FOADM or ROADM)
Your voice was like compressed cat sound and yellow words in boxes were hard to read instead it should be red to easily read, however, it a good simple video
What is the purpose of Transponder convert from optical to electrical than convert again to optical? I mean, what is the different between The Optical before convert to electrical with The optical after convert from electrical?
It's convert optical signal (1310/850) which we also called black and white or grayed into DWDM C band range (1528-1565nm) signal called as collared as DWDM signal only work on this range now L band also supported
Client signal is normally on 850nm/1310nm that we called Black and white signal also. Now this signal to transmit on DWDM we need to convert that signal. We convert first into electrical and that reconvert into optical and assign a ITU-T C band frequency. So our signal transmit on DWDM network Hope this helps.

Can you check for OSC signal? As per your signal flow OSC is getting amplified by amplifier which is not correct.
Informative video
Really nice video with a good piece of information
Amplifier at Mux or at transmitter is called Booster amplifier which amplifies the signal before it leaves
Amplifier at DeMux or at receiver is called Pre amplifier which amplifies before it handover to de-mux
Line amplifier is recommended when the fiber travel the distance of 100-150 km, instead of Line amplifier we can use OADM which also allow us to add or drop channel at some distance
Thanks for adding useful information 🙂
Thanks for the additional info.

Thanks Pranav ! for adding points
Very Imformative, nice presentation thanks.
Thanks for your feedback
Thanks for providing perfect information 😊
Excellent Graphical Presentation for easily understandable. Hats off for that.. Waiting for more videos
Thanks for your feedback.
Thanks sir.. for providing the information
you welcome
Fantastic description
Thanks for your feedback
Thanks for your feedback
This is very excellent demo animation in very plain language really appreciated, and please add same scenario on OTN if possible and would like to thank you in advance sir !
Thanks hope you liked it sure will do
Transmission window (Wavelength Bands)
800-900nm range! is for shoted distance!!
Original O-Band 1260-1360 nm.
Extended E-Band 1360-1460 nm.
Short Wavelength S-Band 1460-1530 nm.
Conventional C-Band 1530-1565 nm.
Long Wavelength L-Band 1565-1625 nm.
Ultralong Wavelength U-Band 1625-1675 nm.
Thanks for the valuable information
Great insight.
Thanks for your feedback ☺️

Perfect!
thanks a lot
Very good knowledgeable video and useful but why you use artificial voice use your natural voice bro you are doing great work you have to proud yourself. RESPECT
Great video. Really appreciate it. :)
Glad it was helpful!
I didn't understand the criteria why sometimes, you don't need an Amplifier after the Mux? Can you please shed some light into this?
❤
great one sir.
would you suggest me some topic on basis of dwdm which we can work for future (for research )?
Can you check for OSC signal? As per your signal flow OSC is getting amplified by amplifier which is not correct.
Yes you are right. Missed this while creating video.. thanks for your feedback
Thx very nice an helpfully video. May you can make a video which Typ of Equipment use as add drop, mux/demux and ampilifr thx a lot
Thanks hope you liked it
Everything here is excellent except for the voice quality... please do consider. Thanks anyway
Thanks hope you liked it sure will do

Nice explanation.
What is filter card and will that fit in this network
Filter is multiplexer and demultiplexer
Smart Cat :D

@@OpticsTrans oohh i see. ok thanks for the explanation.
What is the need for optical to electrical to optical conversation at transponder level?
Client signal is normally on 850nm/1310nm that we called Black and white signal also.
Now this signal to transmit on DWDM we need to convert that signal. We convert first into electrical and that reconvert into optical and assign a ITU-T C band frequency.
So our signal transmit on DWDM network
Hope this helps.
Sound is very low and unclear! Great information though.
Could you improve audio ?
Sure, will work on that thanks.
Its hard to focus with the chipmunk effect in the voice
Why did you put that voice on the video? At least it should be with your voice or some artificial one.
