shield cables and a ground for the entire cable as well

Yesterday we did a cable pull. As an instrumentation worker this is probably as bad and as dirty as it gets. Most cables we pull are 18 gauge single pair. That means there is one black wire, one white wire, and a shield or ground cable. This is enclosed in a grey armored jacket. I’ve been involved in lots of those cables being pulled – not because I’m an apprentice but because it’s part of the job. The cables we had to pull today were 2 – 18 gauge 24 pair cables.Performance cables So inside the Grey cable there are 24 white wires, 24 black wires, 24 shield cables, and a ground for the entire cable as well.On this month’s Cable Talk, we discuss which cable components are critical and what the effects are of temperature fluctuations on sub-standard cables. We demonstrate how cable design, insulation and cable jacket materials collectively determine how effective a cable is in a  fast changing environment.

More than 210,000 users have watched a YouTube video of our data center operations team cabling a row of server racks in San Jose. More than 95 percent of the ratings left on the video are positive, and more than 160 comments have been posted in response. To some, those numbers probably tecnologicamente seem unbelievable, but to anyone who has ever cabled a data center rack or dealt with a poorly cabled data center rack, the time-lapse video is enthralling, and it seems to have catalyzed a healthy debate: At least a dozen comments on the video question/criticize how we organize and secure the cables on each of our server racks. It’s high time we addressed this “zip ties v. hook & loop (Velcro?)” cable bundling controversy.
