摘要
A plenum cable for transmitting various communication signals is described. The cable contains a plurality of twisted pairs of insulated conductors with an insulation that contains substantially no FEP or fluoropolymers. Rather, the insulation contains one or more layers containing an polyolefin material and the outermost layer comprises a flame-retardant polyolefin material. The cable can use a standard plenum-grade PVC jacket. Using this design for the cable lowers the cost by eliminating FEP while using a standard, plenum-grade PVC jacket that requires no modifications.
