Hi, I am wondering if any of the networking gurus out there have had experience with Cat 5EF cabling? I believe that it is basically Cat 5e shielded plenum cable, but I am wondering if there are any other specifications that apply to it and also whether there are different types of Cat 5EF that I should be aware of? I googled it and found some listings, but did not get the answers that I was looking for. Most of my suppliers have never heard of it. Thanks in advance for any help.
