B-to-B BER measurement

[K. Esakki MuthuParticipant]

How can we do measure B-to-B BER measurement?

[Dr Rk SethiParticipant]

Hi esakkimuthu!
Do you mean back to back or something else?
In case of optical fiber communication systems back to back measurement can be performed by simply connecting the output of the transmitter directly to the input i.e., making the length of the fiber zero.

Sorry typing mistake….
output of the transmitter directly to the input of the receiver

[Heitor GalvaoParticipant]

I agree with you

Hi esakkimuthu,

Agree with corrected version of Rk Sethi. You should be able to find the examples of B-to-B schemes in previous OptiSystem forums.

[K. Esakki MuthuParticipant]

Yes,I do agree with you both, thank you, but how these B-to-B BER will be very close to the link with fiber.

[Heitor GalvaoParticipant]

Have good threads on the subject in the Forum search
success

Regarding Back to Back,I found some research that run Back to Back,then Plot the BER versus OSNR,and the noise is the ASE (EDFA main noise) noise,How the noise appear in this case,If we connected Tx to Rx directly according to the definition of back to back.

back to back transmission scheme Describes the system where the receiver and transceiver are directly connected with the transmission link.

thank you all
