Can you check for OSC signal? As per your signal flow OSC is getting amplified by amplifier which is not correct.

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.

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.

@jebssan9 3 месяца назад

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?

What is the need for optical to electrical to optical conversation at transponder level?

@OpticsTrans 3 года назад

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.

@amitparmar144 2 года назад

Can you check for OSC signal? As per your signal flow OSC is getting amplified by amplifier which is not correct.

@OpticsTrans 2 года назад

Yes you are right. Missed this while creating video.. thanks for your feedback

@OpticsTrans 3 года назад

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.

Nice explanation. What is filter card and will that fit in this network

@OpticsTrans 3 года назад

Filter is multiplexer and demultiplexer

@7mzsZyns 2 года назад

Everything here is excellent except for the voice quality... please do consider. Thanks anyway

@OpticsTrans 2 года назад

Thanks hope you liked it sure will do

@Compwib Год назад

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

@Wolfan07 Год назад

Sound is very low and unclear! Great information though.

@petermassage3819 3 года назад

Could you improve audio ?

@OpticsTrans 3 года назад

Sure, will work on that thanks.

@kucretd Год назад

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?

@OpticsTrans Год назад

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

@kucretd Год назад

@@OpticsTrans oohh i see. ok thanks for the explanation.

@praveerfootball 3 месяца назад

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)
