Core Features

●Advanced Technology

Based on the XGSPON standard, it supports symmetric transmission rates of 10Gbps downstream and 10Gbps upstream. It also features automatic dual-mode recognition for GPON and XGSPON, enabling smooth upgrades of existing networks.

●Broad Compatibility

The module is designed to be compatible with both 20PIN and 22PIN interface standards, allowing direct integration with mainstream OLT equipment from different manufacturers. This reduces inventory complexity and simplifies deployment.

●High-Performance Transmission

Offers a high optical power budget of up to 29dB and supports long-distance transmission of up to 20km. Built-in Digital Diagnostic Monitoring (DDM) enables real-time tracking of key parameters such as optical power, temperature, and voltage.

●Stability and Reliability

Designed for industrial temperature ranges to ensure long-term stable operation in harsh environments. Its low-power architecture meets energy-efficient requirements.

Application Scenarios

Uplink connections for OLT equipment in Fiber-to-the-Home (FTTH) networks

Enterprise private line access, base station backhaul, and similar scenarios

Smooth migration from existing GPON networks to 10G PON

Hybrid networking environments with multi-vendor equipment

Installation and Usage

The transceiver adopts a standard SFP+ hot-pluggable form factor and supports plug-and-play operation. Its dual-pin compatibility design eliminates the need to distinguish between interface versions during installation, greatly simplifying maintenance processes. Users can monitor the transceivers status and performance data in real time via the device management system.
