Fiberhome OLT FTTH GPON OLT GDOLT2000L--G High Density Multicast OLT
Overviews
GDOLT2000 is geared to the needs of the next generation optical access, large capacity, high density, convergent full-service optical access platform and supports GPON, EPON access and smooth upgrade to the XG - PON1 and TWDM - PON technology.
XPON system provides abundant xPON terminal, including SFU, SBU, CBU, MDU, MTU, and various types of outdoor terminal.XPON terminals provide 10/100M, 10/100/1000 M, WLAN, RF port, fully meeting the requirements of FTTx network and business access.
Features
l PON ports support downstream and upstream FEC
l Support measurement and diagnosis for optical link parameters
l GPON transmission control layer: single PON port supports 4 K GEMPORT and 1 K T - CONT.Support the NSR DBA and SR DBA;Based on the ITU - T G. 984.3- the ONU auto discovery and manual configuration;Based on ITU-TG. 984.4 and ITU-TG. 988 OMCI protocol stack;Support the the alarm and performance monitoring of ITU-TG.984.3 and ITU-TG.984.4
l VLAN management: create, delete, query VLAN information.VLAN processing and business model are in accordance with the TR - 156, TR - 101 specification requirements. Meet the standarded IEEE 802.1ad VLAN Stacking functions.Support Selective QinQ function .
l Layer two multicast: support IGMP (Internet Group Management Protocol) v1 / v2, v3;Support IGMP Snooping/Proxy, MVR management;Support MLD (Multicast Listener Discovery) v1;Support MLD Snooping/Proxy;The layer two ACL.Based on the purpose/source MAC address, physical ports, Ethernet type, 802.1Q, 802.1P ACL flow classification.
l The user location: support DHCP Option82/18, and PPPoE+.Support flexible configuration and customization development.
