optical fiber receiver

[commeng]

hi my brothers and sisters ( edaboard members)

could u help me to model the figure bellow ( receiver side Only ) using any software, please help me i am really facing a big problem.

i'll appreciate your helpful

tnx a lot

What is the need for the "pump LO"? The photodetector should have RF coming out of it already without any "Pump".

Software? Maybe you need an ap for your Iphone?

Unless you know something about the block diagram you are trying to make, software would just be dangerous to you!

What are you transmitting (digital or analog signals)?
How far are you transmitting them?
Do you care about noise (time jitter, phase noise, AM noise, spurious)?
Cost?
How many are you making?
Any weird environment?

You know, engineering stuff!

i don't care the data is analog or digital

How far are you transmitting them?

i don't care about the distance

Do you care about noise (time jitter, phase noise, AM noise, spurious)?

i don't care about it

Cost?

i don't care about the cost

Any weird environment?

no



tnx for ur replay
