Difficulty: EasyNetwork Cable Types and Connectors

A desktop technician is organizing physical connectivity components for a company hardware refresh. Match each network connector type to its primary deployment scenario.

  • LC (Lucent Connector)Small form-factor fiber optic connector featuring a latch mechanism, used for high-density network connections.
  • RJ458-position 8-contact (8P8C) modular connector used for unshielded twisted-pair Ethernet cables.
  • F-typeThreaded coaxial connector commonly used for broadband internet connections via cable modems.
  • DB99-pin D-subminiature connector commonly used for legacy RS-232 serial communication and console access.

Answer

LC (Lucent Connector) matches the small form-factor fiber optic connector with a latch mechanism. RJ45 matches the 8P8C modular connector for twisted-pair Ethernet. F-type matches the threaded coaxial connector for cable modems. DB9 matches the 9-pin D-subminiature connector for RS-232 serial access.
Each connector corresponds directly to its specific medium and physical standard: LC is a latched fiber optic connector, RJ45 is an 8P8C Ethernet connector, F-type is a threaded coaxial connector, and DB9 is a 9-pin serial connector.

Step-by-Step Solution

1
Identify the media type and physical construction of LC connectors.
LC is a small form-factor fiber optic connector with a push-and-latch design.
Recognizing physical form factors helps match fiber optic components accurately.
2
Identify the physical standard for standard copper Ethernet networking.
RJ45 is the 8P8C connector used on twisted-pair cabling.
RJ45 is the standard connector for twisted-pair local area network connections.
3
Identify the connector type used for coaxial cabling in broadband networks.
F-type connectors thread onto coaxial cable ends for secure broadband connectivity.
Threaded F-type connectors provide reliable RF connections for RG-6 cabling.
4
Identify the connector type used for legacy serial management.
DB9 is a 9-pin serial interface connector used for direct device console connections.
DB9 connectors adhere to RS-232 pinouts for serial communication.

Key Concept

Physical connector specifications for fiber, twisted-pair, coaxial, and serial network media.
