Cat
"Cat" stands for Category and identifies Ethernet cable performance levels. Categories such as Cat5e, Cat6, Cat6A, Cat7, and Cat8 support different speeds and bandwidths. These categories form the foundation of Ethernet cable categories explained because each generation improves performance over the previous standard.
STP
Shielded Twisted Pair (STP) cables contain additional shielding around the wire pairs or the entire cable. This shielding block electromagnetic interference from nearby electrical equipment. STP cables perform especially well in:
- Factories
- Hospitals
- Industrial facilities
It is a great option for various locations where electrical noise is common.
UTP
Unshielded Twisted Pair (UTP) is the most common Ethernet cable construction. Instead of metal shielding, the twisted wire pairs naturally reduce interference. UTP cables cost less than shielded alternatives. It does this while providing excellent performance for:

Different jacket materials meet different installation requirements. This makes it an important part of every Ethernet cord description found on product packaging.
Riser
Riser-rated cable is designed for vertical installations between building floors. Its jacket slows the spread of flames through shafts and risers. Commercial buildings commonly require riser-rated cables whenever network wiring passes through multiple stories inside designated cable pathways.
Plenum
Plenum-rated cable uses special fire-resistant materials that produce very little smoke during a fire. It is required in air-handling spaces where heating and cooling systems circulate air throughout a building. plenum cable meets stricter fire safety regulations. Keep in mind though that they are more expensive.
CMR
CMR stands for Communications Multipurpose Riser. This cable meets NEC requirements for vertical riser installations inside buildings. It offers greater fire resistance than standard communication cable but does not meet the stricter requirements applied to plenum-rated cable used in ventilation spaces.
CMP
CMP stands for Communications Multipurpose Plenum. It represents one of the highest fire safety ratings available for Ethernet cable jackets. CMP cables resist flames and produce very little smoke. This feature them suitable for installation inside environmental air spaces throughout commercial buildings.
CCA (Copper Clad Aluminum)
Copper Clad Aluminum combines an aluminum core with a thin copper coating. Keep in mind that cheaper than solid copper cable. However, CCA has higher electrical resistance and lower durability. Professional installers generally recommend solid copper conductors. This is because they deliver better performance and greater long-term reliability.
Drain Wire
A drain wire appears inside many shielded Ethernet cables. It creates an electrical path that connects the cable shielding to ground. It also helps remove unwanted electrical interference. Proper grounding improves shielding effectiveness and supports stable network performance in electrically noisy environments.
Termination of Ethernet Cable
The quality of a network depends on more than just the cable itself. Proper termination ensures signals travel with minimal loss and devices communicate reliably. The following terms describe the wiring methods and installation techniques used to finish Ethernet cables correctly and maintain consistent network performance.
8P8C
An 8P8C connector has eight positions and eight electrical contacts. many people casually call it an RJ45 connector. 8P8C is the technical name for the plug used on modern Ethernet cables. It provides reliable contact between network devices and structured cabling systems.
RJ45
RJ45 refers to the familiar Ethernet connector found on switches and accessories. It securely locks into place with a plastic clip to prevent accidental removal.it is one of the first ethernet cable names beginners recognize. The [primary reason behind its popularity is that it appears on nearly every Ethernet cable
T568B / T568A
T568A and T568B are two accepted wiring standards that define the order of colored wires inside an Ethernet connector. Both deliver the same network performance when used consistently. Mixing them on opposite cable ends creates a crossover cable instead of a standard straight-through cable.
Punch Down
Punching down means inserting cable conductors into insulation displacement connectors (IDCs) using a punch-down tool. This method is commonly used on patch panels and keystone jacks. Proper punch-down techniques create secure electrical connections without stripping the insulation from each wire.
Keystone Jack
A keystone jack is a modular connector installed in wall plates, patch panels, or surface boxes. Ethernet cables terminate inside the jack while patch cables connect devices from the front. Keystone jacks create clean and organized installations. They also simplify future network maintenance or upgrades.
Crimp
Crimping attaches an RJ45 connector to an Ethernet cable using a dedicated crimping tool. The tool presses metal contacts into each conductor. It does this while securing the cable jacket inside the connector. Proper crimping prevents loose connections that may reduce network performance.
Terminate
Termination is the complete process of preparing an Ethernet cable for use by attaching connectors or keystone jacks. Good termination will:
- Minimize signal loss
- Support table communication
- Extend cable life
Poor workmanship often causes intermittent network problems that are difficult to diagnose.
IDC
An Insulation Displacement Connector (IDC) creates electrical contact by cutting through wire insulation without stripping the conductor first. IDCs are widely used inside keystone jacks and patch panels. This is because they speed installation while maintaining secure and long-lasting electrical connections.
Terms that Describe Structured Cabling Systems (SCS)
Structured cabling creates an organized foundation for every modern network. installers follow standardized layouts that simplify maintenance and expansion. It also helps in troubleshooting. These common terms appear frequently when planning or installing professional network infrastructure.
