Cords from Siemon
Siemon has released a category 6 compatible flat patch cord for in-cabinet network equipment connectivity. These RJ45 copper cable assemblies support category 6 transmission performance in a low-profile construction that provides for tighter bend radius and more easily managed cable routing.
These patch cords use four pairs of 28-gage cable in a rectangular cross section that is only 0.089-in. (2.2-mm) thick. The small profile allows two to three flat cables to be neatly bundled in the space of a single round 24-gage cable.
Smaller gage conductors used in flat cables often result in unreliable connections. Performance testing conducted on some commercially available flat cable cords showed a significant 5 dB drop in return loss margins. Due to an improved contact design and cable construction, the Siemon product showed no return loss degradation after the same testing.
