Network Connector Types - CompTIA A+ 220-801: 2.1

ST connector

• Straight Tip
• Bayonet connector

SC connector

• Subscriber Connector
• Standard Connector
• Square Connector

LC connector

• Lucent Connector
• Local Connector
• Little Connector

RJ11 connector

• 6 position, 2 conductor (6P2C)
• RJ14 uses 6P4C for dual-line use
• Telephone connection

RJ45 connector

• 8 position, 8 conductor (8P8C)
• Modular connector

Wiring standards

RJ11 RJ45 LAN Ethernet/ Network/ Port Cable Tester

• Cables can foul up a perfectly good plan
• Test your cables prior to implementation
• Many connectors look alike
• Do you have a good cable mapping device?

• Get a good cable person
• It's an art

T568A and T568B termination

• Pin assignments from EIA/TIA-568-B standard
• Eight conductor 100-ohm balanced twisted-pair cabling
• T568A and T568B are different pin assignments for 8P8C connectors
• Assigns the T568A pin-out to horizontal cabling

• Many organizations traditionally use 568B
• Difficult to change in mid-stream

• You can't terminate one side of the cable with 568A and the other with 568B
• It won't work.

BNC connector

• Bayonet Neill-Concelman
• Paul Neil (Bell Labs) and Carl Concelman (Amphenol)
• Coaxial cable connector
• RG-58 used in 10BASE2

• Rigid and bulky
• Would often pull loose or disconnect

F-connector

• Cable television
• RG-6/U cable
