What characterizes Type _____ cable?

Type A cable is characterized by being a factory assembly of insulated conductors that includes optical-fiber members enclosed in armor. This design provides several advantages, such as enhanced protection for the optical-fiber components, which are sensitive to environmental factors and physical damage. The armored construction ensures durability and reliability, making Type A cables suitable for various applications, particularly where both electrical and data transmission needs are present.

In contrast, the other options describe different characteristics that do not align with the specifications of Type A cable. The lightweight cable designated for indoor use only suggests a more flexible application that wouldn't require the robust protection provided by the armor. High-voltage applications typically involve cables specifically designed to withstand increased electrical stress, which is not the primary function of Type A. Finally, cables that exclusively contain non-metallic components suggest alternatives to armored designs that may not provide the same level of durability and protection as Type A cables.
