BT-PON EPON ONU Product Introduction

I. What is an EPON ONU?

An EPON ONU (Ethernet Passive Optical Network Optical Network Unit) is a core user-side terminal device in an EPON fiber optic access system, and a crucial bridge connecting the operator’s EPON fiber optic network and user terminal equipment. Its core function is to receive optical signals from the passive optical distribution network (ODN), efficiently convert them into electrical signals directly usable by the user, and simultaneously transmit the electrical signals from the user terminal to the optical line terminal (OLT). Finally, through an EPON fiber optic network conforming to the IEEE 802.3ah standard, it provides users with high-speed data, voice, video, and other comprehensive telecommunications services.

As an important component of the EPON system, the EPON ONU, with its passive transmission advantages, features resistance to electromagnetic interference, long transmission distance, high bandwidth utilization, and low maintenance costs. It is widely used in various scenarios such as homes, enterprises, and smart cities, and is one of the core devices for achieving “last mile” fiber optic access.

II. Types of BT-PON EPON ONUs

BT-PON, as a professional optical communication equipment solution provider, offers a rich product series of EPON ONUs. These ONUs are categorized into various types based on device functions and application scenarios, precisely matching the differentiated needs of different users and comprehensively covering various FTTx deployment scenarios such as residential, enterprise, and industrial applications. The main types include:

• Wi-Fi ONU: Integrates wireless LAN functionality, providing high-speed Wi-Fi connectivity for mobile phones, computers, smart TVs, and other wireless terminals without the need for an additional router. It supports both wired and wireless access, making it a mainstream choice for home and small office scenarios.
• PoE ONU: Supports PoE (Power over Ethernet) functionality, providing both network access and power to connected IP cameras, wireless APs, IP phones, and other terminal devices via Ethernet cable. This simplifies cabling, reduces deployment costs, and is widely used in security monitoring, enterprise offices, and other scenarios.
• CATV ONU: Integrates CATV (Cable TV) functionality, providing simultaneous high-speed internet access and cable TV viewing, meeting the one-stop needs of home users for both internet and television, and achieving a convenient “triple play” experience.

Furthermore, the entire V-SOL EPON ONU series supports compatibility with mainstream OLT equipment, featuring loop detection and fault alarm functions to ensure stable network operation. It also allows for centralized monitoring and configuration through the VSOL INCE intelligent management platform, significantly improving operational efficiency.

III. Detailed Specifications of the 1GE+1FE Wi-Fi EPON ONU

This high-performance Wi-Fi EPON ONU from BT-PON is equipped with one Gigabit Ethernet port (GE) and one 100Mbps Ethernet port (FE), balancing high-speed wired access with flexible wireless connectivity. Suitable for home broadband, small office scenarios, and other applications, it can meet the daily needs of multiple devices simultaneously accessing the internet, playing high-definition video, and online office work. Its core Wi-Fi specifications are as follows:

• Protocol Standard: Compliant with IEEE 802.11b/g/n protocols, offering excellent compatibility and seamless connectivity with various Wi-Fi-enabled terminal devices. It is also backward compatible with older 802.11b/g devices, adapting to the needs of different users.
• Operating Frequency: 2.400-2.4835GHz ISM band. This band offers wide coverage and strong wall penetration, suitable for wireless signal coverage in homes and small spaces. No additional frequency band licensing is required.
• Transmission Performance: Supports MIMO (Multiple-Input Multiple-Output) technology, increasing data transmission rates through spatial multiplexing, up to 300Mbps. This meets the high-speed data transmission needs of high-definition video-on-demand and large file downloads, while also improving signal stability and anti-interference capabilities.
• Antenna Configuration: Employs a 2T2R (2 transmit, 2 receive) architecture, paired with two 5dBi external omnidirectional antennas, effectively expanding wireless coverage, reducing signal blind spots, and improving transmission stability when multiple devices are connected simultaneously. Suitable for the coverage needs of large homes and small office spaces.
• SSID Support: Supports multiple SSIDs (Service Set Identifiers), allowing users to set different Wi-Fi names and passwords as needed. This separates guest networks from home networks, ensuring private network security while facilitating temporary guest access and enhancing flexibility.
• Channel Configuration: Supports 13 operating channels, allowing flexible selection based on the surrounding wireless environment. This effectively avoids channel congestion, reduces interference from devices on the same frequency band, and ensures stable and smooth Wi-Fi transmission.
• Modulation Type: Supports three modulation types: DSSS (Direct Sequence Spread Spectrum), CCK (Complementary Code Keying), and OFDM (Orthogonal Frequency Division Multiplexing). DSSS and CCK are used to improve anti-interference capabilities for low-speed transmission, while OFDM is used for high-speed data transmission, catering to the needs of different transmission scenarios and adapting to complex wireless environments.
• Encoding Scheme: Supports four encoding schemes: BPSK, QPSK, 16QAM, and 64QAM. It automatically switches according to wireless signal strength, using the higher-order 64QAM encoding to improve speed when the signal is strong, and switching to the lower-order BPSK encoding to ensure connection stability when the signal is weak, achieving a dynamic balance between speed and stability.

Overall, with its stable performance, flexible interface configuration, and excellent Wi-Fi coverage, it is a Wi-Fi EPON ONU product that balances practicality and cost-effectiveness, perfectly suited for broadband access needs in home and small office scenarios.
