  Op­ti­cal ref­er­ence dis­tri­b­u­tions have be­come an in­dis­pens­able asset for fem­tosec­ond pre­ci­sion syn­chro­niza­tion of free-elec­tron lasers. At FLASH and for the fu­ture Eu­ro­pean XFEL, laser pulses are dis­trib­uted over large dis­tances in round-trip time sta­bi­lized fibers to all crit­i­cal fa­cil­ity sub-sys­tems. Novel Laser-to-RF phase de­tec­tors will be used to pro­vide ultra phase sta­ble and long-term drift free mi­crowave sig­nals for the ac­cel­er­a­tor RF con­trols. In this paper, we pre­sent the re­cent progress on the de­sign of a fully in­te­grated and en­gi­neered ver­sion of the L2RF phase de­tec­tor, to­gether with first ex­per­i­men­tal re­sults demon­strat­ing so-far un­ri­valed per­for­mance.
