Shielded jacketed cable was developed to fulfill the growing need for external or I/O connections. The product consists of insulated wires surrounded by a copper foil or braid shield. Shielded jacketed cable offers good cross talk reduction when driven in either balanced or unbalanced modes. The shield is very effective in reducing EMI and minimizing ESD effects. Pleated Foil-Covered cable, for example, uses a solid pleated copper foil to provide 35db average shielding effectiveness while still retaining flexibility. Shielded cables are available in flat or round constructions.
