Coherent UDWDM–PON Guard Band for Legacy Video and 10G–NRZ Systems

Not Accessible

Your library or personal account may give you access

Abstract

We experimentally analyze the required guard band of coherent optical UDWDM networks transporting 16×1.25 Gb/s – QPSK at 3.125 GHz frequency grid to coexist with Video and 10G – NRZ transmissions. Using simple DSP based ONU, guard bands of only 0.8–1.6 nm are achieved.
