There are always customers asking about Huawei GPON boards differences. For example: What’s the differences between H802GPFD, H805GPFD, and H806GPFD?
The article will tell us some differences among them.

1.From version:
 
H802GPFD, H805GPFD, and H806GPFD stand for different versions.“H802” version, “H805” version, and “H806” version. The order from the old to new is H802GPFD> H805GPFD > H806GPFD
 
2.From Benefits:
 
H802GPFD, H805GPFD, and H806GPFD same benefits:

High density and energy saving

High density and low power consumption, supporting 2048
access users

High reliability

Chip-level type B protection (single-homing and dual-homing) and
type C protection (single-homing and dual-homing) switching
Real-time rogue ONU detection and isolation, ensuring stable
service running

Efficient OAM

Variable-length of OMCI, improving upgrade efficiency and
reducing break off time

A maximum distance difference of 40 km between two ONUs
under the same PON port (board capability), simplifying network
planning

External Interfaces

16 GPON ports with SFP optical modules:

l Max. split radio:
Ø Class B+: 1:64
Ø Class C+/C++: 1:128

H805GPFD and H806GPFD benefits, but H802GPFD without:
 
High-value services

4-level HQoS, improving user experience
9216 jumbo frames, greatly improving transmission efficiency

3.Data Comparison:

From the above data, we can see that although they are all GPFD 16 port GPON board, but different versions, the parameters are still different, especially MAC addresses and 4-level HQoS.
The current mainstream version is the H805 version, when you are buying a product, you can ask the seller to indicate the version. Some sellers do not inform the clear version, causing customers to receive very old H802GPFD, etc. Although the price is low, the product version is old and cannot meet customer needs.
