Fiber Optic Connectors Lecture Notes

Overview

• Importance of using the correct connector type.
• Different types of fiber optic connectors.

SC Connector (Subscriber Connector)

• Also known as Square Connector or Standard Connector.
• Design: Square shape.
• Usage:
  • Pushes into the connection and snaps in place with a lock.
  • To remove, pull on the connector to unlock it.
• Application:
  • Commonly used in data centers.
  • Supports individual fibers, often paired for transmit and receive functions.

LC Connector (Local Connector)

• Also referred to as Lucent Connector or Little Connector.
• Design: Smaller than SC connector.
• Usage:
  • Has a clip on top to lock it in place.
  • Push down on the clip to release the lock.
• Application:
  • Can be paired for simultaneous use in transmit and receive.

ST Connector (Straight Tip)

• Design: Uses a bayonet connector.
• Usage:
  • Push into interface, twist to lock.
  • Reverse the twist to remove.
• Features:
  • Protective ferrule around the fiber.
  • Bayonet mechanism prevents accidental dislodging.

MPO Connector (Multi-fiber Push-On)

• Design: Contains 12 individual fibers in a single cable connection.
• Usage:
  • Lock similar to SC connector.
  • Referred to as MTP as well, name by Corning.
• Features:
  • Efficient use of space by containing multiple fibers.
  • Locking mechanism on top, fibers visible under light.

Key Points

• Each connector type has distinct locking mechanisms to prevent accidental disconnections.
• MPO is advantageous for high-density applications due to its multiple fiber capacity.
• Understanding connector types and their function is crucial for effective fiber optic management.
