Mr. GMOkay, new fiber to the office is in the conduit and the old fiber (both the working multi-mode fiber and the too-short single-mode fiber)'s all bundled up and put away! That took forever, but it was worth it! And hey, that's one more SFP+ port open on my Brocade ICX-7250 switch, since now the office is on the same breakout cable from the Mellanox SX6036 as the living room!
