is strictly GPON, newer variations (often labeled as or hardware revision dual-mode ) include a hardware chipset capable of autosensing both GPON and EPON wavelengths.
: Always backup your current configuration file via System Tools > Configuration File before proceeding.
Technically, both standards use the same wavelengths (1310nm/1490nm). This means the laser is the same. The difference lies in the layer and the firmware logic . Therefore, by changing the firmware, you can tell the Qualcomm (or Huawei chipset) inside the HG8245H to speak EPON rather than GPON. firmware huawei hg8245h gpon to epon verified
Some newer HG8245H variants are factory-built as XPON. These can often be switched via the command line (CLI) or the web interface without a full firmware flash.

The terminal paused. Leo held his breath. Then, the words flashed: Update Successful. Rebooting system.
That translator was a custom, highly experimental firmware image sitting on his laptop. He had spent the last forty-eight hours modifying the core binary files, stripping out the GPON driver locks, and injecting low-level EPON instructions he had reverse-engineered from a broken rival modem. This means the laser is the same
: Ensure the label on the bottom explicitly says "HG8245H" (not HG8245 or HG8245Q, as firmwares are strictly non-compatible).
