Siemon network splitter

Y-adapters are available as "splitters" which convert one 4-pair jack into two jacks. The Y-adapters utilize Siemon's patented UP-2468 plug, which allows adapters to be used in 6- or 8-position jacks. The adapter body can be rotated 180 degrees to view either the colored icons or the Y-adapter pinouts, which are printed on the opposite side.
