1. Product Overview

The ETGH is a carrier-grade, high-density 16-port EPON (GE-PON) service board designed for the ZXA10 C300/C320/C220 series OLT platforms. It provides asymmetric 1.25Gbps EPON transmission (downstream 2.488Gbps / upstream 1.244Gbps) over single-mode fiber, supporting PX20, PX20+, and PX20++ SFP optical modules.The ETGH enables scalable FTTH/FTTB triple-play services (HSI, VoIP, IPTV) and supports up to 1,024 subscriber ONUs (max 1:64 split ratio per port). It features hot-swappable design, advanced DBA, and carrier-grade security for reliable, cost-effective fiber access networks.
