Multiple Choice

Direct buried service wire is commonly available in which pair configurations?

Direct buried service wire is sized by how many separate conductors (pairs) you need to carry the subscriber lines into a building. The most commonly stocked configurations are two-pair and five-pair. Two-pair cables cover typical residential service with room for a spare line, while five-pair cables support a small business with multiple lines without jumping to larger trunk cables. Larger multi-pair cables, such as six to thousands of pairs or twenty-five to four thousand two hundred pairs, are used for distribution or trunk applications—not for a direct-burial service entry to a single premises. One-pair cables exist, but they are not the standard for everyday direct burial service.
