The D-Egg, (Dual optical sensors in an Ellipsoid Glass for Gen2) is one of the new optical modules designed for the coming IceCube Upgrade at the South Pole. With two 8-inch high-quantum efficiency photomultiplier tubes (PMTs) per module and improvements in overall design, D-Eggs offer an increased effective photodetection sensitivity that is 2.8 times larger than that of the current IceCube optical sensors. Mass production of over 300 D-Eggs has been completed, with all modules now undergoing Final Acceptance Testing (FAT) before deployment in the Antarctic ice. This involves detailed characterisation of each module at cold temperatures to collect valuable calibration data, as well as detect possible hardware related failures. While FAT is still on-going, current results indicate we will exceed the required 277 modules for deployment.
