Q:What is the difference between H80D00GPFD01, H80D00GPFD02?
A: We don’t suggest you order according to this BOM, this BOM is mostly used for manufacturer producing purpose, Basically choosing GPFD card, we just need to know: 1, H802GPFD, H803GPFD or H805GPFD? 2, with B+, C+/C++ SFP?

H805GPFD and H807GPBD are most selected items.
Q: Does GPFD has any version requirement of OLT software?
A: Yes, only V800R008C01, V800R009C00 or above version support GPFD, also please make sure your OLT software included the package of your GPFD board version.
Q: Can I use 1:128 split ratio with B+ SFP Module?
A: Yes, but not suggested, most of our customers even use C+ module, are max using 1:64 split ratio.
Q: Can I get technical support from thunder-link.com if we purchase GPFD from you?
A: We will able to provide technical support service for customers whose OLT and GPON card are both from us, kindly note we will charge for the technical support service. We suggests customers purchase the OLT and GPFD card from the same professional supplier so as to avoid compatible and technical issues.
Q: Does the GPON SFP Module included in GPFD?
A: Yes, 16 C++ SFP Module are included for free.
Q: Can I do twice splitting with GPFD?
A: Yes, you can, just make sure the optical power is within the receive side range.
Q: Can I purchase GPFD with C+ module?
A: Yes.
Q: Can I use a 3rd party ONT with GPFD?
A: We don’t suggest so, as the understanding of TR069/OMCI protocol may different between different vendors.
Q: What is the power consumption of GPFD board?
A: Between 45~73W.
