<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">To me it makes sense a cable that somehow converted fibre light to copper electrical (or vice versa) would be more expensive than either an all copper or all
fibre cable because such cables would have to have some sort of electronics built in (even if just photoelectric cells) to do the signal conversion.

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">I’ve never seen such a cable though so would be interested in what they look like. Years ago I did see a box that would convert copper rj11 to fibre (and
vice versa). The purpose of that was for locations that had high lightning strikes (e.g. Florida) so one could do distance wiring runs not affected by electrical storms. It probably was worth it for such sites.

<p class="MsoNormal" style="margin-bottom:12.0pt">Those are the direct copper. They have a sfp+ connector on each end and cost like they are gold. I've been doing fiber for cheaper. Weird.<o:p></o:p></p>

<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Tahoma","sans-serif";color:black">I know that we have some special copper cables that have SFP+ ends. We are going to Cisco 10GB switches out of Broadcom 57711 cards. They were in range of several
hundred $$$ each, but cheaper than the fiber option. I can get the info from our Network team, if that is of any use to you?<o:p></o:p></span></p>
