Description
The XGS PON transceiver ONU SFP is a high-performance optical module designed for 10G symmetric passive optical network (XGS-PON) applications. It integrates advanced transmission and reception technologies into a compact SFP+ form factor, enabling reliable and high-speed fiber access for modern broadband networks.
This module features a 1270nm burst-mode DFB transmitter and 1577nm APD receiver, delivering stable 10Gbps upstream and downstream performance in compliance with ITU-T G.9807.1 standards. With built-in automatic power control (APC) and temperature compensation, it ensures consistent optical output across varying environmental conditions.
Designed for seamless integration into OLT/ONU systems, it supports digital diagnostic monitoring (DDM), providing real-time visibility into key operating parameters such as optical power, temperature, voltage, and bias current.
