The AONT-1421 has been optimized for small business and residential homes to provide triple play services. It can work in both bridge and Routed mode.

Advanced High Bandwidth GPON technology

The AONT-1421 is fully FSAN (ITU-T G.984& G.988) compliant 2.488 Gbps downstream and 1.244 Gbps upstream GPON systems.


The AONT-1421 contains both L2 switch and L3 routing gateway with port forwarding, NAT and NAPT address translation, built-in PPPoE support for HSI, and an integrated stateful packet inspection firewall and application-layer gateway (ALG. Included as part of the gateway function are DHCP client, DHCP server and DNS server for IPv4 and IPv6.

Quality of Service

The AONT-1421 supports extensive QoS features, including ToS/DSCP to 802.1p mapping, and 802.1p to DSCP mapping, Traffic classification and QoS based on layer 3 and layer 4 header.prioritizable queues, ensures that tiered service offerings based on different bit-rates and QoS can be readily supported.
