Overview
This lecture covers common types of fiber optic connectors used in large computing environments and data centers, focusing on their features and how they are used.
Fiber Optic Connector Challenges
- Switches have limited physical space, so smaller connectors allow more ports on devices.
- Fiber connectors must support both transmit and receive signals, often in combined formats.
Common Fiber Optic Connector Types
LC Connector (Local Connector)
- LC connectors are small, allowing high port density on network equipment.
- Each LC connector houses two separate fiber connections for transmit and receive.
- Can be used as combined or individual fiber strands, depending on network needs.
ST Connector (Straight Tip)
- ST stands for Straight Tip and features a long ferrule at the end.
- Uses a bayonet locking mechanism that secures the connection with a quarter turn.
- Designed for durability in network environments.
SC Connector (Subscriber or Square Connector)
- SC stands for Subscriber Connector, sometimes called Square Connector for its shape.
- Can be used in combined connectors or separated into individual fiber runs.
- Frequently chosen for its simplicity and reliability.
Key Terms & Definitions
- LC Connector — A compact fiber optic connector with two fibers for transmit and receive.
- ST Connector — A fiber connector with a straight tip and bayonet lock.
- SC Connector — A square-shaped fiber connector, also called Subscriber Connector.
Action Items / Next Steps
- Review the physical appearance and locking mechanisms of LC, ST, and SC connectors.
- Familiarize yourself with where each connector type is commonly used in your network environment.
