In summary:

1, XGPON&GPON combo board CGHF is the mainstream in Chinese market, because XGPON is more and more popular, but XGSPON still not largely commercial deployed here.

2, Some European countries such as Spain internet service provider already configure XGSPON in their network, but downstream still XGPON ONT connected.

3, CGID, CGHF, CSHF, CGHD and CSHD supported functions are same, and all these 4 boards don’t support D-CCAP.
