Hi Sebastien. I tested it with simple media converter, it probably didn't care about EEPROM. I tested it before shipping, so maybe connection was damaged in some other way? Greg

I suggest building them from a passive SFP copper cable (e.g. http://www.fs.com/products/36649.html) cut in half, with a male (motherboard or disk) connector soldered at the end. Some switches or media converters require a EEPROM or the LOS signal that the copper cable provides, and the male connector is more solid mechanically than soldering a SATA cable inside a SFP. The cable I got from you had its transceiver line connections damaged, plus it cannot work on my media converter due to the missing EEPROM or LOS (not sure which - LOS would be relatively easy to fix, just connect to ground). The FS.com cable above is properly detected. Sébastien _______________________________________________ ARTIQ mailing list https://ssl.serverraum.org/lists/listinfo/artiq
