OLT2406 Series
2U Temperature-Hardened 6-slot Chassis GPON OLT
Flexible FTTH applications
The Zyxel OLT2406 Series provides up to 2K 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 up to 1:128, 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.
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.
