What protocol does Hunan Hengyang Telecom Optical Fiber Cat use, EPON or GPON?

Thank you for your support to China Telecom. According to your description, you can see the following:

EPON provides fixed uplink and downlink 1.25 Gbps, adopts 8b/ 10b line coding, and the actual rate is 1Gbps.

GPON supports multiple rate levels, and can support asymmetric uplink and downlink rates, including downlink 2.5Gbps or 1.25Gbps, uplink 1.25Gbps or 622 Mbps. According to the actual needs, the uplink and downlink rates are determined, and the corresponding optical modules are selected to improve the cost performance of optical devices.

Hunan Hengyang Telecom has an agreement on optical fiber cats.

I hope it helps you, and I wish you a happy life!
