As for integrated electro-optical hardware that does coherent optics, I&amp;#x27;d like to point at SFP optics; the ones that are sufficiently non-fancy with their electronics (up to 10km single-mode optics; no high-end-multimode optics; no exotic coherent optics) should not have a retimer on the RX side. Once you go to 1-Gbit/s transceivers you&amp;#x27;ll find ones with a linear RX stage; those should be suitable for rigging simple homodyne interferometry by just feeding…&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/2011.05313/"&gt;Paper and discussion history&lt;/a&gt;.
