thank you

[Swapandeep KaurParticipant]

thank you sir. and sorry for deviating from the topic

[Swapandeep KaurParticipant]

sir i want to ask how to solve e raised to the power of 4e15 meaning e^4*e15

[Swapandeep KaurParticipant]

sir how will we calculate e to the power (4*10 to the power 15)

[Swapandeep KaurParticipant]

ok sir, got it, thank you

[Swapandeep KaurParticipant]

sir erbium ion density is given as e+025 . does it mean 10 to the power of 25?

[Swapandeep KaurParticipant]

sir i was getting output power lesser than input power , so when i substituted it in the formulae (pout-pin)/ppump=PCE=lambda,p/lambda,s and Gain=(lambda,p/lambda,s)*ppump/pin i got negative values because i took input power as power of wdm tramsmitter

[Swapandeep KaurParticipant]

sir for calculating gain, we will take input power obtained at the dual port analyser at the amplifier?

[Swapandeep KaurParticipant]

no sir, i am getting negative gain

[Swapandeep KaurParticipant]

sir meanwhile i am trying out with the normal edfa and hopefully, i am getting the results….

[Swapandeep KaurParticipant]

sir i have to perform the mathematical analysis of the optical amplifiers and that involves gain and noise figure calculation but in our simulation ,we have already fixed the gain and noise figure. should i change it to the normal edfa component? also i read that gain of edfa becomes negligible with increase in input power and in our simulation , we have set it to 10 db (for noting non linearity effects). what should be done?

[Swapandeep KaurParticipant]

sir the graphs which i sent to you, my sir(guide) wants me to mathematically check them through ber and dispersion formulas. like i set dispersion to 2 ps/nm/km

[Swapandeep KaurParticipant]

sir please give some good mathematical analysis of optical amplifiers. is maths from “fiber optic communication by gp aggarwal” fine?
“

[Swapandeep KaurParticipant]

sir do you have mathematical analysis of BER and dispersion?

[Swapandeep KaurParticipant]

thank you sir. in the thesis, which i sent to you, its shown on pg 27, fig 1.12 that it is because of the gain spectra of the two amplifiers.and given on pg 28 that the gain spectra of the two have opposite slopes………is that the reason. then they must subtract
