Fiber Optic Connectors Lecture Notes

Overview

When working with fiber optics, it is crucial to understand the different types of connectors available and ensure the correct one is used for each connection.

SC Connector (Subscriber Connector)

• Names:
  • Subscriber Connector
  • Square Connector (due to its shape)
  • Standard Connector
• Usage:
  • Pushes into the connection and locks in place.
  • Requires pulling to unlock and remove.
• Common Application:
  • Widely used in data centers.
  • Supports individual fibers, often combined in pairs (one for transmit, one for receive).

LC Connector (Local Connector)

• Names:
  • Local Connector
  • Lucent Connector
  • Little Connector
• Design:
  • Smaller than SC connector.
  • Has a clip for locking into place.
• Usage:
  • Requires pushing down on the clip to release the lock.
  • Can be combined in pairs for transmit and receive functions.

ST Connector (Straight Tip)

• Design:
  • Uses a bayonet connector.
  • Requires a twist to lock and unlock.
• Protection:
  • Features a protective ferrule around the fiber.
  • Bayonet design helps prevent accidental disconnection.

MU Connector (Multifiber Push On)

• Design:
  • Designed to save space; includes 12 individual fibers in a single cable.
  • Locking mechanism similar to the SC connector.
• Other Names:
  • Referred to as MTP (a Corning term).
• View:
  • Side view shows the lock; fibers appear as small dots.
  • Direct view with light shows all 12 fibers clearly.

Summary

• Importance of Locking Mechanisms:
  • Each connector type has a unique locking mechanism to ensure stability and prevent accidental disconnection.
• Efficiency and Space:
  • MU connectors maximize efficiency by fitting more fibers into a smaller space.

Understanding these connectors, their locking mechanisms, and usage is crucial for effective fiber optic management and ensuring stable connections in various environments such as data centers.
