Scaling limitations in transparent optical networks due to low-level crosstalk

Abstract

As transparent optical networks are scaled up in size, stringent constraints must be placed on the in-band crosstalk generated by their components. Measurements show that transparent networks corrupted by interferometric signal-crosstalk beat noise from only 8 crosstalk fields require component crosstalk levels <-35 dB. Good agreement with theory is shown.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
