A keystone jack is a crucial component in networking and telecommunication systems that is used to connect ethernet cables from various devices to a central hub or switch. It is essentially a small plastic secumbent that is inserted into a wall plate, patch panel, or surface mount box and has a receptacle to accept a RJ45 plug of an Ethernet cable. Keystone jacks are most commonly used in commercial and industrial settings, such as data centers, offices, and educational institutions. They are also frequently used in residential homes, allowing homeowners to connect their devices to the internet.
Keystone jacks come in various designs to accommodate different types of cables, including Cat5, Cat5e, Cat6, and Cat6a cables. They also come in different colors to help identify different types of cables, depending on their use and location.
One of the main benefits of using keystone jacks is their versatility. They can be easily swapped out or replaced when necessary without having to remove the entire wall plate or patch panel. This makes it easy for technicians to upgrade or modify the cabling system without causing any major disruption to the network.
In addition to their versatility, keystone jacks are also easy to install. They can be snapped into place using a special tool known as a punch down tool or a simple tool tip, depending on the type of jack and cable being used. Additionally, many keystone jacks come with integrated strain relief, which helps prevent the cable from becoming detached or damaged over time.
Overall, keystone jacks are an essential component of any networking and telecommunication system. They provide a reliable and easy-to-install solution for connecting Ethernet cables from various devices to a central hub or switch, and their versatility makes them a popular choice in both commercial and residential settings.
