EDGE Uniboot Jumpers allow for the quick-and-easy conversion from a TIA-568 A-B polarity to a TIA-568 A-A polarity without exposing the fibers or needing any tools. This jumper comes with a straight-through polarity from the factory, but you can convert it to a flipped jumper. This uniboot design allows one cable to carry both fibers, reducing the jumper bulk when routing. EDGE Uniboot Jumpers are manufactured with Corning® CleanAdvantage™ Technology with Optimized Dust Caps, eliminating the need for scoping and cleaning prior to initial field connection.
