Zyxel OUL2420 End-of-Life & EOSL Dates
Zyxel has published end-of-life dates for the OUL2420. End of global marketing and end of service and support are taken from Zyxel's own end-of-life table, linked below.
Every tracked Zyxel OUL2420 SKU group is past Zyxel end of service life (last group Dec 2018). Units in production should be treated as unsupported. For past-EOSL units, weigh third-party maintenance, spares, replacement, or a documented run-to-failure. Zyxel’s named migration path: OLT2406.
