GPON ZyXEL OLT 2406 Series - GPON Solution

GPON ZyXEL OLT 2406 Series

GPON ZyXEL OLT 2406 Series:

GPON ZyXEL OLT 2406 Series provides up to 1024 FTTH subscribers with four PON line cards that support four ITU-T G.984 GPON fiber links or four GbE line cards for 16 active non-blocking Gigabit Ethernet fiber links. The GPON line card supports the split ratio of at least 1:64, while each of the four SFP slots supports both class C+ and class B+ transceivers for different service reaches. The temperature-hardened design allows service providers to install OLT2406 Series in street cabinets to provide services for more subscribers.

  • Sixteen ITU-T G.984-compliant GPON ports with each port supports up to 64 ONTs
  • Two management switching cards plus two power module for redundancy
  • Four 10 GbE and two GbE uplink ports
  • 10 GbE backplane bandwidth per line card slot for non-blocking services
  • Four PON or GbE ports per line card
  • ITU-T G.984.1 type A and type B for protection
  • Temperature-hardened
  • All front-access and hotswappable design


The OLT2406 Series supports Dual Stack. By supporting MLD, IGMP as well as other comprehensive IPTV functions, the OLT2406 Series can be deployed in either IPv4 or IPv6 environments. Users can also provision protocol-based VLAN for IPv6 traffic or assign various IPv6 access control list profiles for each subscriber.

Traffic protection

The OLT2406 Series provides two types of PON protection defined in ITU-T G.984, type A and type B, to prevent fiber cuts or PON card failures. With all common modules supporting redundancy, the OLT2406 Series is able to avoid single-point failures to ensure non-stop user traffics, and service providers can benefit from applying VLAN bridging, VLAN translation, VLAN isolation and Multicast VLAN to quickly setup services for various types of subscribers. The OLT2406 Series also supports comprehensive QoS and complete traffic management for efficient triple-play services.
