The straight and crossover Cat5e Ethernet patch cables, in eight colors and 3 to 50-ft lengths, support up to 1,000 Mbps. The cables are designed to reduce the EMI effects by use of a single metal foil shield wrapped around the entire set of four twisted shielded pairs. The RJ45 connectors are also shielded against electrical interference. The 350-MHz cables exceed all Cat5e TIA/EIA standards, and reduce both impedance and structural return loss (SRL), compared to standard 100‑MHz cables.
