It seems like you are looking for information about ZTE GPON, EPON, XG PON, and XGS PON OLT devices, specifically the ZXA10 and C620 models. Here's a brief introduction to these terms and devices:

1. GPON (Gigabit Passive Optical Network): A high speed fiber optic data transmission method that uses passive optical splitters to enable point to multipoint communication.

2. EPON (Ethernet Passive Optical Network): A standard for high speed data transmission over fiber optic networks using Ethernet protocol.

3. XG PON (10 Gigabit Passive Optical Network): An upgrade to GPON, offering higher data rates of up to 10 Gbps.

4. XGS PON (10G EPON symmetrical): A symmetrical version of XG PON, providing equal upload and download speeds of up to 10 Gbps.

5. OLT (Optical Line Terminal): A device used in fiber optic communication networks to connect multiple users to a single fiber optic line.

6. ZTE: A Chinese multinational telecommunications equipment and services company.

7. ZXA10: A series of ZTE OLT devices that support various PON technologies, including GPON, EPON, XG PON, and XGS PON.

8. C620: A specific model within the ZTE ZXA10 series, which is an OLT device supporting GPON and XG PON technologies.

9. AD or DC OLT: Refers to the power supply type of the OLT device. AD (Alternating Current) and DC (Direct Current) are the two types of power supplies used in these devices.

10. 1GE or 10GE: Refers to the data transmission rates supported by the OLT device. 1GE (1 Gigabit Ethernet) supports data rates of up to 1 Gbps, while 10GE (10 Gigabit Ethernet) supports data rates of up to 10 Gbps.

In summary, you are looking for information about ZTE's ZXA10 and C620 OLT devices, which support various PON technologies and offer different power supply options and data transmission rates.
