What type of cable is defined as a CM cable?

The term "CM cable" stands for "Communications Multiservice" cable, which is commonly associated with unshielded twisted-pair (UTP) cables that are designed for indoor use. These cables are made to meet specific safety standards, particularly related to fire hazards, and are typically used in networking applications such as Ethernet connections in homes and offices.

CM cables are not suited for outdoor use because they lack the necessary materials and protection against environmental factors. This makes the classification important for installers and technicians to ensure that they choose the appropriate type of cable for the specific installation conditions. Therefore, understanding the nature and intended use of CM cables is crucial for maintaining optimal performance and safety in broadband installations.
