In Optisystem simulation tool how to change the ONU data rate in passive optical network??
The Passive in PON means that you do not have amplifiers but does not say anything about the transmitter type which can be a tuneable laser and at the receiver you will have to have some tunable filter
Let at receiver I am having tunable filter. from the optical line terminal (OLT) i send two wavelengths one at 10 Gbps and another at 2.5 Gbps. now I want to receive these transmitted signals at ONU. now I want to ask how I change the data rates between 10gbps and 2.5 Gbps.
sorry I read too fast, to change the data rate you will need a transmitter with the higher bw you want to operate. A directly modulated laser able to afford 10 gbps modulation, for instance. Or you can imagine to have two transmitters, actually silencing one. At the receiver also the PD BW will need to accomodate the larger data rate thus introducing higher noise than needed for the lower data rate. It's unclear to me wether you are asking how it is done or how could be done.
I as asking how it could be done??
means I have to change the optical filter BW used at ONU to change its data rate
I noticed this question. I will try to explain it according to my understanding. You got two wavelengths, one with 10g and the other 2.5g. If you want to change the received data rate, just tune the central wavelength of the filter to make it align with the wavelength you want. That's EXACTLY what the TOF is used for in TDM/WDM–PON.
