Abstract:	The Grade of Service (GoS) or ONU rejection probability in coherent UDWDM-PONs with ONU lasers under limited tunability is evaluated. Each active ONU is assigned an exclusive wavelength channel, which is managed by heuristic Wavelength Assignment (WA) schemes. With a take rate of 90%, GoS values below 0.1% are achieved, but when statistical subscribing is considered, the GoS is dramatically improved.
