25 Pair Burial Telephone Cable is suitable for outdoor applications without the use of conduit. The cable is filled with water resistant gel and UV resistant. The conductors are 24awg and follow the industry standard color code for twisted pair cables. Direct burial telephone cable must not be run for more than 50ft inside buildings (per the National Electrical Code).

- Solid, annealed copper; size 24 AWG
Insulation:
- Dual insulation consisting of an inner layer of foamed polyolefin surrounded by a solid polyolefin skin, color-coded in accordance with telephone industry standards
Twisted Pairs:
- Insulated conductors are twisted into pairs with varying lay lengths to minimize crosstalk
Core Assembly:
