Jelly Filled air core telephone cable
Core Construction:
Conductors:
• Solid, annealed copper; sizes 19, 22, 24 and 26 AWG
InsuIation:
•Option 1 Solid, high density polyethylene, color- coded in accordance with telephone
industry standards
•Option 2 Conductors are dual insulated with an inner layer of foamed,natural polyolefin
covered by an outer layer of solid,colored polyolefin. The conductor insulation is color
coded in accordance with industry standards
Twisted Pairs:
• Insulated conductors are twisted into pairs with varying lay lengths to minimize crosstalk
Core Assembly:
• 25 pairs and less: pairs are assembled together in a single group
• More than 25 pairs: pairs are arranged in groups, each group having a color-coded unit
binder
• 1200 pairs and larger are mirror image color code
Filling Compound:
•The core assembly is filled with an 80 degree petroleum compound, completely filling
the interstices between the pairs and under the core wrap
Core Wrap:
• Non-hygroscopic dielectric tape applied Iongitudinally with an overlap
Aluminum Shield:

• Corrugated 0.008" aluminum tape applied Iongitudinally with an overlap
Jacket:
• Black, linear low density polyethylene
Application(s):
• Intended for aerial installation by attachment to a support strand
Compliances:
• Telcordia (Bellcore) Specification GR-421-CORE
• RoHS Compliant (effective 1/1/10)
Packaging:
• Standard lengths are shipped on returnable steel reels or on non-returnable wood reels
when requested
• Non-standard packaging is also available
