What are three commonly followed standards for constructing and installing cabling? (Choose three.)

In the construction and installation of cabling, the following three are commonly followed standards:

1. Pinouts: This refers to the arrangement of conductors in the cable to connect with the corresponding pins or contacts in connectors. Correct pinouts are crucial for the network to function properly, as they ensure that signals are properly transmitted and received.
2. Cable lengths: Standards often specify the maximum length for different types of cables to ensure signal integrity. For example, the Ethernet standard for Cat5e/Cat6 cabling specifies a maximum length of 100 meters (328 feet) to prevent signal degradation.
3. Connector types: The use of standardized connectors ensures interoperability and proper physical connection. Common types include RJ-45 for Ethernet cables and LC/SC connectors for fiber optics.

Other factors like tensile strength of the plastic insulator, cost per meter, and connector color, while they may be considered during the selection and installation process, are not standardized attributes in the same sense as pinouts, cable lengths, and connector types.
