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.
- Color Codes for Stranded, 100Ω Patch Cord
| Option 1 | Option 2 | |
|---|---|---|
| white/blue - blue | pair 1 | green - red |
| white/orange - orange | pair 2 | black - yellow |
| white/green - green | pair 3 | blue - orange |
| white/brown - brown | pair 4 | brown - slate |
- Note:
- Because of their identical pair groupings, patch cords terminated with either T568A or T568B pair assignments may be used interchangeably, provided that both ends are terminated with the same pin/pair scheme.
