1. Product Overview

The EFGH is a high-density, carrier-grade 16-port EPON (GEPON) service board designed for the ZXA10 C600/C650 series OLT platforms. It provides 16 independent EPON interfaces to connect and manage up to 1,024 subscriber ONUs/ONTs (1:64 split per port) for FTTH, FTTB, and enterprise access networks. Supporting full EPON protocols, high-speed data transmission, and advanced management features, the EFGH delivers reliable, high-bandwidth triple-play services (HSI, VoIP, IPTV) with carrier-grade stability.
