H801GPMD is an 8-port GPON OLT Interface Board, which works with the CMC to provide GPON access service in the MSO scenario.
Table 1 shows the quick spec.
| Model | H801GPMD |
| Forwarding capability | 20 Gbit/s |
| T-CONTs per PON port | 1024 |
| Service flows per PON board | 6144 |
| Maximum frame size | 2004 bytes |
| MAC addresses | 16384 |
| Maximum distance difference between two ONUs under the same PON port | 40 km from V800R013 |
H801GPMD provides these benefits:
Ј High-precision clock and time synchronization: 50-ppb frequency synchronization and 100-ns phase synchronization
Ј High reliability
- Chip-level type B protection switching, shortening the switching time to less than 50 ms
- Type C protection dual-homing, providing geography-level disaster recovery
- Real-time rogue ONU detection and isolation, ensuring stable service running
Ј Easy OAM
- Variable-length OMCI, improving upgrade efficiency and reducing break off time
- A maximum distance difference of 40 km between two ONUs under the same PON port, simplifying network planning
- 1:64 eOTDR, supporting accurate fault demarcation and quick fault locating
H801GPMD provides these external interfaces:
8 GPON ports with SFP optical modules:
Ј Max. split radio:
- Class B+: 1:64
- Class C+/C++: 1:128
