Datacom introduces DmOS 10.8, a release that consolidates the DmOS 10.x series launched in recent months. Throughout this cycle, the operating system has evolved in terms of optical capacity (DWDM), switch synchronization and operation, IP/MPLS features, management/observability, and GPON — enhancing performance, predictability, and end-to-end operational efficiency.
