Corelink 4 Port 1G EPON OLT – Dual Power Optical Line Terminal for FTTH Networks in Bangladesh The Corelink 4 Port 1G EPON OLT is a high-performance optical line terminal designed for modern FTTH (Fiber to the Home) and FTTB (Fiber to the Building) networks. It delivers reliable gigabit connectivity, supporting up to 256 ONUs through a 1:64 split ratio — ideal for ISPs, enterprises, and telecom providers building scalable broadband infrastructure in Bangladesh. This dual-power OLT (AC 100–240V / DC -48V) features 4 EPON ports (SC/UPC), providing 1Gbps symmetric bandwidth per port. With advanced VLAN, QoS, and IGMP Snooping/Proxy support, it ensures stable performance for Internet, IPTV, and VoIP services. The system can be easily managed through CLI, Web GUI, SNMP, and EMS, making it convenient for both small and large-scale deployments. Built for long-term reliability, the Corelink OLT operates efficiently with only 20W power consumption and has an MTBF of 100,000 hours. Fully compliant with IEEE 802.3ah EPON standards, this device guarantees strong compatibility and future-proof network expansion.
