The stock web interface (192.168.100.1) will not allow PON mode switching. You need Telnet.
If you truly need EPON, buy an EPON ONT (e.g., HG8240E, HG8547E) instead of forcing a protocol change. The HG8245H5 is widely documented as GPON-only in official Huawei datasheets.
Firmware Huawei HG8245H5 GPON to EPON 2021 Exclusive: A Comprehensive Guide
The Huawei HG8245H5 is a popular Optical Network Terminal (ONT) device used in Fiber-to-the-Home (FTTH) networks. It supports Gigabit Passive Optical Network (GPON) technology, which provides high-speed internet connectivity to homes and businesses. However, some users may want to convert their HG8245H5 from GPON to Ethernet Passive Optical Network (EPON) technology, which is also widely used in FTTH networks. In this article, we will explore the firmware upgrade process for the Huawei HG8245H5 GPON to EPON conversion in 2021.
What is GPON and EPON?
GPON (Gigabit Passive Optical Network) and EPON (Ethernet Passive Optical Network) are two different technologies used in FTTH networks to provide high-speed internet connectivity. Both technologies use optical fibers to transmit data, but they differ in their architecture and protocols.
GPON is a point-to-multipoint network technology that uses a single optical fiber to connect multiple users to a central office. It offers high-speed data transmission rates of up to 2.5 Gbps downstream and 1.25 Gbps upstream.
EPON, on the other hand, is a point-to-point network technology that uses a separate optical fiber for each user. It offers high-speed data transmission rates of up to 1 Gbps downstream and upstream.
Why Convert HG8245H5 from GPON to EPON?
There are several reasons why users may want to convert their HG8245H5 from GPON to EPON:

"firmware huawei hg8245h5 gpon to epon 2021 exclusive" refers to a specialized software modification designed to reconfigure the Huawei EchoLife HG8245H5 Optical Network Terminal (ONT). This conversion allows a device originally built for (Gigabit Passive Optical Network) to operate on (Ethernet Passive Optical Network) infrastructure. The Technical Need for Conversion
Typically, GPON and EPON are incompatible due to different signaling protocols and hardware architectures. However, "exclusive" 2021 firmware releases emerged in online communities to bypass these restrictions, primarily for users moving between ISPs with different network standards. : Default state; supports up to 2.5 Gbps downstream.
: Converted state; typically limited to 1.25 Gbps symmetric speeds. xPON (Dual Mode)
: Some unofficial firmwares attempt to turn the device into an

The Huawei HG8245H5 is a high-end routing ONT. Sporting a Gigabit gateway, dual-band Wi-Fi (supporting 802.11ac), and two POTS ports for voice, it became a staple for ISPs globally. Out of the box, the H5 variant is primarily manufactured and sold as a GPON (Gigabit Passive Optical Network) device.
GPON and EPON (Ethernet Passive Optical Network) are competing standards. GPON uses ATM/GEM encapsulation and offers higher bandwidth efficiency (2.488 Gbps downstream), while EPON uses standard Ethernet frames (1.25 Gbps symmetric). Because the physical transmission layer differs, a standard GPON stick cannot natively communicate with an EPON OLT (Optical Line Terminal).
Or so it was thought.
Firmware Conversion and Compatibility: Assessing the Feasibility of Running EPON Software on the Huawei HG8245H5 GPON ONU (2021 Review)
In the intricate world of Fiber-to-the-Home (FTTH) networking, the Optical Network Terminal (ONT) is often viewed as a locked "black box." However, for network technicians and advanced users, the year 2021 marked a significant turning point for one of Huawei’s most ubiquitous devices: the HG8245H5.
While the hardware remained static, a specific wave of "exclusive" firmware releases in 2021 allowed for the re-provisioning of GPON units to EPON standards. This process—technically known as a "mode switch"—transformed the utility of surplus inventory and changed how ISPs manage their fiber ecosystems.

In the world of ISP hardware, the Optical Network Terminal (ONT) is often viewed as a "black box"—a sealed device provided by the carrier that you have no control over. But for the network enthusiast and the independant ISP technician, there is a holy grail of modifications: Protocol Conversion.
Specifically, converting the Huawei HG8245H5—a ubiquitous GPON terminal—to function on an EPON network.
Back in 2021, a specific wave of firmware exploits and tools circulated within the Chinese technical community (and niche forums like 4PDA). This wasn't just a simple password change; it required a fundamental rewrite of the device's PON layer. This article explores the technical reality of that "2021 Exclusive" conversion, why it matters, and the extreme risks involved.
This study examines whether the Huawei HG8245H5—an optical network terminal (ONT) designed for GPON—can be converted to run EPON firmware, the technical barriers to doing so, security and legal implications, and recommended safe alternatives for operators seeking EPON capability. Conclusions: direct firmware replacement is effectively infeasible for most users due to hardware/bootloader differences, vendor locks, and legal/operational risks; interoperable solutions or gateway devices are the practical options.
