Possibility of Bonding
Just saw readme mentions that LAN RJ45 is 1Gbps, limiting the client bandwidth.
I have many other models including Huawei, ZTE. FiberHome, some support 10ge/Xg-pon, we can get over 1Gbps by using 2 x GE ports, tested with PPPoE on RouterOS, bridge mode on ONT). Everything seems fine, get ~940Mbps before, ~1200Mbps+ after bonding in speedtest.net. (The ISP here gives around 25% of the burst & redundancy).
Simply set bonding-rr (not lacp, not alb, rr only) mode on router, ONT does not require config.
(Feedback from friends, Bonding is also working in routing mode.)
I haven't hg8045q here, but maybe worth a try, just in case someone is interested in speed over 1G. 😀
The only method I tested to get the full 2gbps connection was utilizing an SFP module with a broadcom-based SFP+ network adaptor with special drivers that enabled 2.5gbps SFP linkage. More Information on this can be found here: https://www.dslreports.com/forum/r32458588-
It may also be possible to source a compatible link converter from fibre to 2.5gbps RJ45 but I haven't tested such a method. I also have not tested other forms of hardware that may be compatible.
