Receiver Sensitivity

[pooja rawat]

I wish to know what is the maximum and minimum value of receiver sensitivity that we can use for our systems in optisystem.

The sensitivity of an electronic device, such as a communications system receiver, or detection device, such as a PIN diode, is the minimum magnitude of input signal required to produce a specified output signal having a specified signal-to-noise ratio, or other specified criteria.

Thanks

Can please someone help.

Hi Pooja,

I agree to most of the replies made by the forum members. I want to add here that receiver sensitivity is the average power required by a receiver to detect a signal and in my opinion we should choose it as small as possible.

Thank you

HI pooja rawat…
you have rightly mentioned that the sensitivity of an electronic device is the minimum magnitude of input signal required to produce a specified output signal having a specified signal-to-noise ratio, or other specified criteria. Receiver sensitivity parameter is an important factor.Also the value of this parameter should be as much low as possible which means that the receiver requires less power to detect a signal.
I hope you find it helpful.

Hi Ubaid Bhat

That is fine but can you tell me what are the values. My query is about the values we can use for our systems in optisystem.

Thanks

Hi Pooja mam..
What are you designing..?
i think it will depend on your system application..you check this topic where it is mentioned..

Receiver Sensitivity

i hope this will help you..

HI pooja rawat…

It has been rightly mentioned by ubaid that receiver sensitivity is an important parameter and its value should be as much low as possible which means that the receiver requires less power to detect a signal.As far as your query on the exact values is concerned it will depend on the type of application for which you are designing… Try to look into the link provided by jyoti… May be it will be of help..

Hi Sahil Singh.

I am perhaps looking for the values. Thanks Anyway for your help.

Thanks

[pooja rawat]

Hi Jyoti Raina.
I am designing a TWDM PON network. I wanted to know what values are permissible for the receiver sensitivity. I hope i get some replies that would answer my question.
Anyway Thanks for your effort.

Thanks

Hello Pooja,
i think jyoti is right in saying that selection of receiver sensitivity is application dependent.
In optisystem the default receiver sensitivity lies between -100 to -30 dBm.
I hope this will help.
Thanks & regards

HELLO POOJA,
I have replied you on the other thread as well but for your convenience let me repost it here too.
If you go through the previous replies you will find that receiver sensitivity will be determined by the need of the system implementation.. You can see that we have discussed that it is the application that will decide the values selected for the sensitivity …If you want your receiver to be less sensitive then choose low negative value else higher negative value. I hope this will help you in getting some idea.

[pooja rawat]

Hello Remo
Thanks for your help. I appreciate that but i am looking for the minimum and maximum values for receiver sensitivity. I tried to google but could not get any specific values.
Thanks
Regards

[pooja rawat]

Hi Fayiqa
Thank you for responding. I already replied at your previous thread. anyways i was mentioning that I think i got a little idea about it. But still is there any limit on choosing the minimum and maximum values for receiver sensitivity. I tried to google but could not get any specific values. Please help if you can.

Thanks
Regards

[FAYIQA NAQSHBANDI]

HELLO POOJA,
I am not sure about the values but yeah if i found any shall let you know definitely. But i strongly believe the values are application specific.

Thanks & Regards

Hi Pooja.
I hope you get your required and appropriate answers from our members. All The Best.

[SAHIL SINGH]

Hello Pooja,
As far as the values are concerned i am not pretty sure about that..As correctly pointed out by Romeo in optisystem the default receiver sensitivity lies in between the range of -100 to -30 dBm.

Thanks & regards

Hello Sahil Singh.
Thanks for your efforts. I appreciate.

Hi Pooja,

Please let me know if you find out the exact values..

[pooja rawat]

Hi Sahil.
I don’t know the exact values as per the suggestions there are no fixed values.

Pooja

[Ankita Sharma]

Hi Pooja,

A very nice question posed by you… But I am also unaware about the exact values..

Regards
Ankita

[pooja rawat]

Hello Ankita.
I guess as mentioned by other members it is application dependent.
Anyways thanks for your concern.

Thanks

[Ankita Sharma]

Hello Pooja,

Well I thought you were looking for some precise values..I do understand it varies from application to application..Thanks for the information..

Regards
Ankita

[Remo De Suza]

Hi all.
I think there are no precise values for the receiver sensitivity. You can take them as per your system application as aforementioned by other members.

Regards
Remo

[Ankita Sharma]

Hi Remo,

Thanks for the information.. Infact I too was of the same opinion that the values of receiver sensitivity are application specific…

Hello Ankita
You are welcome. I am though not sure but most probably that is how it is. Anyway thanks for appreciation.

Hi,
The sensitivity of any electronic device, like a communications system receiver,
or any detection device, such as a PIN diode APD diode , is the minimum magnitude of input signal
required to produce a specified output signal having a specified signal-to-noise ratio.

We are always confused to sensitivity and responsitivity.
If anyone has good understanding of both , please share your idea.

Seeking your response

Rajguru

[pooja rawat]

Hello Rajguru,
Thank you for the useful information and yes i agree to what other forum members have said. These are two different parameters

[nagesh kuknoor]

Hi Rajguru,

Sensitivity and responsitivity are two different things. You can think responsitivity as part of sensitivity and if you check the mathematical expression you can see sensitivity depends on responsitivity of the photodetetor.
Thanks

hi rajguru sir..
i too agree with nagesh sir..these are two different things.

Hi Shafeen,

Thanks…

[Rajguru M. Mohan]

Hi everyone,
Yeah, i also agree that responsivity and sensitivity are not same.
The responsivity is usually defined for the steady state.
responsivity as the ratio of output voltage and optical power.
The photodiode response typically falls off for signal frequencies above some detection bandwidth.
while sensitivity is sensitivity is the lowest detectable light level,
which is typically determined by detection noise and significantly influenced by the required detection bandwidth.

Thanks for suggestion and response.

[FAYIQA NAQSHBANDI]

HI RAJGURU..

I appreciate that..Actually responsitivity is one important factor in determining the sensitivity of receiver..You were intermingling both..Anyway it is a learning process. Cheers.
