Compositions for compounding, extrusion, and melt processing of foamable and cellular polymers
First Claim
1. A communications cable comprising:
- a support separator configured to provide a plurality of channels for receiving transmission media, said support separator comprising a first foamed polymeric material;
at least one optical fiber disposed in one of said channels;
at least an electrical conductor having an American Wire Gauge (AWG) in a range of about 22 to about 26 and capable of carrying at least about 10 watts of electrical power disposed in another one of said channels;
an insulation configured to at least partially cover said electrical conductor; and
a jacket configured to surround said support separator and said transmission media, said jacket comprising a second foamed polymeric material;
wherein said foamed polymeric material of any of the support separator and the jacket comprises a plurality of cellular structures characterized by cells having a size in a range of about 0.0005 inches to about 0.003 inches.
