Connect your fiber drop cable to the optical port. Verify that the lights up solid green, confirming a successful handshake with the EPON OLT. If you plan to perform this conversion, tell me: The current hardware version on your device sticker The software version currently installed on your ONT Whether your ISP uses LLID or MAC authentication Log in using the super administrator credentials (typically
Converting a Huawei HG8245H from GPON to EPON via firmware is highly dependent on your specific hardware revision. While software parameters can toggle optical modes on newer dual-mode silicon, older legacy hardware cannot bridge this physical layer gap. Always back up your original configuration XML files and stock firmware binaries before making low-level system modifications.

Network migrations frequently require hardware adaptability. Internet Service Providers (ISPs) often switch their optical line terminal (OLT) architecture from GPON to EPON. This shift leaves thousands of Huawei HG8245H GPON optical network terminals (ONTs) unusable without a firmware modification.
Check the sticker on the bottom of your device. Look for revisions that mention dual-mode or specific chipsets (like Hisilicon) capable of switching modes.
If you need a guaranteed EPON ONT, buy an HG8240 (EPON native) instead. But if you enjoy the tinker – go for it.
