such that odd numbered fibers are Position A at one end and Position B

achieved by using consecutive fiber numbering (i.e., 1,2,3,4...) on
both ends of an optical fiber link, but the 568SC adapters shall be
installed in opposite manners on each end (i.e., A-B, A-B... on one

small form factor), polarity may be achieved either by using the above
method for the 568SC or by using reverse-pair positioning. </font></li>
