Flexible FTTH applicationsN/AThe Zyxel OLT1404A/OLT1408A 4/8-port GPON OLT provides up to 500/1K FTTH to subscribers with 4/8 ITU-T G.984 GPON fiber links. The GPON OLT supports split ratios of up to 1:128 while each SFP slot supports both class C+ and class B+ transceivers for different service reaches. The 4/8-port pizza box OLT is a cost-effective solution in thinly populated regions and the 1U design makes installation easier thanks to its small size and compact design.N/AN/AVarious interfaces for network applicationsN/AThe Zyxel 1U OLT supports various interfaces including eight Gigabit Ethernet optical interfaces eight Gigabit Ethernet RJ-45 interfaces and four 10G interfaces. The 8 GE optical interfaces support P2P services for enterprise users to enjoy guaranteed bandwidth. The RJ-45 GE interfaces facilitate local server connections for vertical applications or aggregate access network technologies like MSAN VoIP AG and more. Customers can have more flexibility and unified management to smoothly integrate even more services. The 10G interfaces can be used with ERPS function for ring protection or to cascade other GPON devices without sacrificing bandwidth.N/AN/AAdvanced triple-play and mass deployment functionalitiesN/AThe Zyxel OLT1404A/OLT1408A supports QoS security and multicast functionalities; it also features IGMP snooping to prevent unnecessary multicast forwarding to all subscribers which optimizes bandwidth utilization for multicast applications such as broadcast video. The OLT1404A/OLT1408A also supports the multicast VLAN feature that distributes the source to all VLANs requesting video streams.N/AN/AHigh-reliability network deploymentsN/AThe Zyxel OLT1404A/OLT1408A is a temperature-hardened remote system with a power supply compatible with either AC or DC power sources and an extra battery charger function. The OLT can operate in environments with temperature ranging from -40C to 65C which allows it to meet various environment conditions worldwide. Since the OLT1404A/OLT1408A comes with battery charger function customer doesnt need an additional Switch Module Rectifier (SMR) to power the OLT1404A/OLT1408A as well as to charge the backup battery at the same time. It not only reduces CAPEX but is also easier to deploy.N/AN/ASophisticated OAM&P featuresN/AThe Zyxel OLT1404A/OLT1408A provides various management methods such as local console port Telnet and SNMP v1/v2/v3-based EMS (NetAtlas EMS) along with a web GUI. The management functions include alarm and status surveillance configuration management performance management and fault management. The NetAtlas EMS also provides view-based MIB management that partial MIB objects can be defined and accessed for customization and security purposes. The OLT1404A/OLT1408A offers a user-friendly web GUI that allows operators to manage through any browser on any PC laptop or smart phone.
