To me this looks like a Chinese version of the NSA FIREWALK product. Which is a network implant built into a RJ45 jack intended to be soldered onto a motherboard. The FIREWALK info came out with the Snowden leaks in 2013 and the tech was years old at that time.
I am not able to say a lot more, but when I worked for a major defence contractor in 2006-2007 in Afghanistan, building WAN links in and out of the country by satellite, hardware implants were found in equipment. Not our equipment, but it was close enough to our operations that we were briefed on it and made aware.
