Description

The HSGQ E04D is a high-performance 4-port EPON OLT that provides scalable fiber access for FTTx, ISPs, and enterprise networks. It supports IEEE 802.3ah EPON standard and is backward compatible with multiple ONU types, offering seamless integration and high reliability for network operators.

Equipped with 4 EPON SFP PON interfaces, 4 Gigabit RJ45 copper uplinks, and 4 Gigabit SFP uplink slots, it can serve up to 256 ONUs (64 per PON port) with a maximum transmission distance of 20 km. The system uses a dual AC (100–240V) power supply for redundancy and high availability.

The E04D supports a rich Layer 2/3 feature set including VLAN, STP/RSTP, IGMP snooping, QoS, port isolation, MAC management, ACL, and 802.1X authentication. Advanced management via CLI, SNMP, WebGUI, and SSH allows easy configuration and monitoring. With a compact 1U rackmount design, lightning protection, and wide environmental tolerance, the E04D is built for stable performance in professional EPON deployments.
