Twisted pair communication cables with foamed PVDF jackets
A communication cable suitable for Power over Ethernet (“PoE”) applications may include one or more twisted pairs of individually insulated conductors that are insulated with a material that includes fluorinated ethylene propylene. Additionally, a jacket that includes foamed polyvinylidene fluoride may be formed around the one or more twisted pairs. The PoE cable may have a higher maximum temperature rating and be capable of transmitting higher amperage signals than conventional PoE cables while satisfying applicable electrical performance criteria.
