Q: Does GPBH has any version requirement of OLT software?
A: No, just make sure your OLT software included the package of your GPBH board version.
Q: Can I use 1:128 split ratio with B+ SFP Module?
A: Yes, but not suggested, most of out customers even use C+ module, are max using 1:64 split ratio.
Q: Can I get technical support from thunder-linkcom if we purchase GPBH 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 GPBH card from the same professional supplier so as to avoid compatible and technical issues.
Q: Does the GPON SFP Module included in GPBH?
A: Yes, 8 B+ SFP Module are included for free.
Q: Can I do twice splitting with GPBH?
A: Yes, you can, just make sure the optical power is within the receive side range.
Q: Can I use a 3rd party ONT with GPBH?
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 GPBH board?
A: Between 32~46W.
