Seen on the FCC, a mysterious adapter: the A2657. This is an Apple product likely intended for Apple Stores or internal use, approved in 2022.
The device is rumored to run iOS and features a black block with two Ethernet ports and a USB-C port. It also includes Wi-Fi, and the manual (visible in the documents) explains that it secures network access. The document isn’t very clear on the actual functionality, but it seems it needs to be placed between two devices for secure access.
