Icky-pick or icky-pic is a gelatinous cable compound used in outdoor-rated communications cables, including both twisted-pair copper cabling and fiber-optic cabling. [1] [2] "PIC" is the abbreviation for "plastic insulated cable". The cable is filled with an "icky" substance. The filled cable itself, therefore, is called an "icky PIC".
One or more twisted pairs, called a drop wire. The drop wires typically connect to a splice case, located in line for aerial cables, or in a small weather protected case for underground wiring, where the local cabling is connected to a secondary feeder line. These cables contain fifty or more twisted pairs.

Direct-buried cable (DBC) is a kind of communications or transmissions electrical cable which is especially designed to be buried under the ground without any other cover, sheath, or duct to protect it. [1] Most direct-buried cable is built to specific tolerances to heat, moisture, conductivity, and soil ...
If colored white, it typically may be used for splicing neutral wires in a device box, while leaving a pigtail free for connection to a device (such as a receptacle). If colored green, the assembly is intended to be used as a grounding pigtail, similar to the feedthrough twist-on wire connectors without a permanently-attached wire.

The splicing of copper wires happens in the following steps: The cores are laid one above the other at the junction. The core insulation is removed. The wires are wrapped two to three times around each other .
