Here is a helpful write-up regarding the 2021 firmware context for the FiberHome SR120A.

The proliferation of fiber-optic broadband has necessitated the mass deployment of complex optical network terminals (ONTs) and residential gateways. FiberHome, a prominent telecommunications equipment vendor, supplies the SR120A series for these deployments. Despite their ubiquity, these devices often operate with firmware that receives infrequent updates and lacks transparency regarding internal code auditing. This paper focuses on the firmware architecture of the SR120A specifically from the 2021 release cycle, a period marked by the transition from proprietary management protocols to more standardized TR-069 implementations. Understanding the inner workings of this firmware is vital for network administrators and security researchers aiming to mitigate risks in ISP infrastructure. fiberhome sr120a firmware 2021
