Modular Jacks and MRJ21 Product
Stacked Modular Jacks
Product Facts
■ Performance exceeds Near
End Crosstalk (NEXT)
requirements of -40dB on all
pair combinations at 100
MHz per EIA/TIA 568A
■ All Stacked Jacks have
Category 5 performance.
■ Meets or exceeds FCC Part
68 rules and regulations
with standard pc board foot-
prints
■ Low profile and narrow
width allow more ports to be
packed into less space
