Passive Optical Networks (PONs) have revolutionized fiber-optic communication, providing cost-effective and high-bandwidth solutions for residential and business users. Within a PON architecture, several key components play a crucial role, including the Optical Line Terminal (OLT), Optical Network U

​With the continuous advancement of communication technology, Gigabit-Capable Passive Optical Networks (GPON) have gradually become the mainstream access method. Consequently, the maintenance of GPON equipment has become increasingly important. At the Technical Center of Xinrui Technology, we have accumulated extensive maintenance experience with both mobile and Tietong GPON equipment. Today, I would like to share some valuable insights on GPON equipment maintenance.

1. Introduction to PON NetworkPON (Passive Optical Network) is a fiber-optic access technology that establishes physical connections between users and network providers using passive devices such as optical splitters. The primary advantage of PON networks is their ability to provide high-bandwidth,

The interface of OLT devices is designed to be slanted for several key reasons:Firstly, slanted interfaces facilitate cable management. In a complex network environment, cables can easily become tangled and difficult to organize. By angling the interface, cables can be routed more cleanly and effici

Gigabit Passive Optical Network (GPON) technology has emerged as a leading choice for fiber-to-the-x (FTTx) networking solutions, offering high-speed, high-bandwidth data transmission over a passive optical network. The key component in any GPON deployment is the GPON module, which enables efficient

The core chips in coherent optical modules can be divided into two categories: optical chips, including bipolar IQ modulation, lasers, coherent optical mixers, and balanced detectors; Electric chips, including modulator drivers, transimpedance amplifiers (TIAs), and DSP chips. From the perspective of chip manufacturing technology, current electric drives are based on Si or SiGe materials using CMOS standard process flow. Due to power consumption and performance requirements, the core DSP chip needs to adopt a relatively advanced 7nm node process.

Optical modules are key components in optical communication systems, responsible for converting, transmitting, and receiving optical signals. With the rapid development of optical communication technology, optical modules have become increasingly diverse in types and applications. This article aims

Gigabit Passive Optical Network (GPON) is a communication technology used for fiber to home (FTTH) broadband installation. The GPON architecture has two key devices: Optical Line Terminal (OLT) and Optical Network Terminal (ONT). These two components are responsible for establishing reliable communi

In fiber-optic communication networks, the Optical Line Terminal (OLT) plays a crucial role as the central aggregation point for data transmission. Understanding the relationship between the OLT upstream port, PON (Passive Optical Network) port, and downstream Optical Network Units (ONUs) is essenti
