i realize it is kinda randomly asking but do anyone know of a good place to watch new movies online ?
how do we calculate overall attenuation loss in optical fiber?
Sir attenuation increasing after coloring in natural fibre pls tell me the reason
Thankyou sir ❤️💫

Sir, in the formula for attenuation, shouldn't it be log(output power/input power) instead of log(input power/output power). Maybe I am wrong. Please clarify

If you get +ve attenuation then it should be Pin/Pout and visaversa.
super video

The submarine fiber optif is he has the same attenuation of fiber optique that we use in our houses for internet??

Engineering Funda in fact i want study the attenuation and dispersion and absoprtion in submarine fiber optical and my question is if i study those (attenyation dispersion....) in optical fiber that we do in our house. My studies can be the same as if do it in submarine fiber in other word attenyation and dispersion in realité it is the same in water???

Yeah, cable is completely isolated from water. I don't know material used for submarines optical Fiber but science will not change.

shout out kay Batang at Diane
sir its not aatenuation its attenuation
Attenuation loss=10*log(Pout/Pin)
Formula is wrong
