Twisted-Pair PCords and Cross-Connect
Jumpers
- Patch cords should use stranded cable for
adequate flex-life.
- Stranded cables must meet the minimum performance
requirements for horizontal cable except that 20 percent more
attenuation for UTP is allowed by '568-B.2 and 50 percent more
attenuation is allowed by '11801:2002 for UTP and F/UTP.
- Color-code for cross-connect jumpers: One
conductor white, the other a visibly distinct color such as
red or blue.
- Performance markings should be provided to
show the applicable transmission category in addition to safety
markings.
- Insulated O.D. of stranded wires should be
0.8mm (0.032 in.) to 1mm (0.039 in.) to fit into a modular plug.
- Production performance specifications for
plug cord assemblies are addressed in '568-B.2.
