Copper Network Connectors

Each application uses may use different connectors.

RJ = registered jack

RJ - X Standardzedd telecomunition network interfact for connecting voice and data equipment to a service provided by a locl ecxhcnage carrire or long distance carrier. X is a place holder for 11, 45 ect.

RJ - 11

RJ -45 are for twisted pair.

RG - X Radio Guide. Associated with coaxial cable for different applicaions like High speed internet, TV ect

RG-6

RG-59

RJ-11 - Standard connector for telephone wireing.

6 position 2 condutior 2 2p2c, ideal for phone, not sutiable fro hgh speed intenrt.

RJ-45

Standard for data in ethernet

8 position 8 conductior. widley used to connect devices in a lan. Can support high-speed data transfers.

F- Type 0 Standard for cable TV and coaxial .

RG-6 USED FOR COAXIAL in resedintal and commercial settings, have a F type . can be used for digital TV high frequency, high speed internet services.

RG-59 OLDER SPEC for coax cables, used to be very common for tv and radio signal transmiission.

BNC Bayonet Neill Conceilmen - another type of coax connecter that is used to push and twisht style connector. quick, secure, reliable, stable. erroniously called british navil connecor

Cable Connectors (CompTIA Network+ N10-009)

RJ (Registered Jack)

RJ-11
- 6P2C (6 positions, 2 conductors).
- Standard for telephone wiring, DSL.
- Not suitable for Ethernet/high-speed data.
RJ-45
- 8P8C (8 positions, 8 conductors).
- Standard for Ethernet (Cat 5/5e/6/7/8).
- Used in LANs for high-speed data (100 Mbps – 40 Gbps).

👉 Exam Tip: RJ-11 = phones, RJ-45 = Ethernet.

Coaxial Cable Connectors

RG = Radio Guide rating (specifies thickness & impedance).
RG-6
- Modern standard for cable internet & digital TV.
- Supports high frequencies, long distances.
- Uses F-Type connector.
RG-59
- Older, lower bandwidth; used for analog video, CCTV.
- Shorter distance support.
- Also uses F-Type connector.

Connector Types

F-Type
- Standard screw-on connector for cable TV, broadband (RG-6).
- Residential and commercial settings.
BNC (Bayonet Neill–Concelman)
- Push-and-twist (bayonet) style.
- Used for coax in CCTV, older networking, test equipment.
- Provides secure, quick connect/disconnect.
- Sometimes mis-called “British Naval Connector.”
