The abbreviation LC for fiber optic connectors stands for Lucent Connector and literally means “translucent/transparent connector.”

LC connectors are among the smallest connectors, measuring 1.25 mm, which is about half the size of SC or FC connectors.

Due to their small size, they belong to the small form factor (SFF) category for connectors.

This makes LC fiber optic connectors ideal for use in angled and confined spaces, such as transceivers.

Another advantage is the possibility of using a clip to convert a simplex connector into a duplex connector.

Steps to Connect an LC Connector

  1. Preparation: Ensure the work area is clean. Gather the necessary tools and materials, including LC fiber connectors, fiber strippers or cutters, cleaning tools (e.g., alcohol wipes, cleaning pen), a fusion splicer (if needed), and testing equipment (e.g., power meter, OTDR).
  2. Fiber Stripping: Use a fiber stripper or specialized cutting tool to carefully strip the protective layer off the fiber, exposing the fiber core. Ensure the core is clean and free of contaminants.
  3. Cleaning the Fiber: Use alcohol wipes or a fiber cleaning pen to clean the fiber core’s surface, removing any dust and fingerprints. Ensure the fiber core is dry and spotless.
  4. Inserting the Fiber: Carefully insert the cleaned fiber core into the LC fiber connector, ensuring it fully enters the connector and aligns with the internal metal contact faces. Use a fiber insertion tool (e.g., V-groove clamp) to secure the fiber firmly inside the connector.
  5. Inspecting the Connector: Use a magnifying glass to inspect the fiber connection, ensuring the core is not bent or damaged and is properly aligned with the connector’s metal contact faces. Test the connection for signal loss using a power meter to ensure it is within acceptable limits.
  6. Securing the Fiber: Place the connected LC fiber in an appropriate patch panel or distribution frame and secure it with screws. Ensure the fiber remains stable and does not move.
  7. Recording and Labeling: Document the fiber connection details, such as number, color, and length. Label the fiber for future identification and management.

Perform these steps in a dust-free, dry environment to ensure the quality of the fiber connection.

If you are not familiar with the process, it is recommended to have a professional technician complete the task.

Once the connection is made, conduct thorough testing to ensure the transmission performance meets the required standards.

Importance of Avoiding Dust and Moisture

Avoiding dust and moisture during LC connector installation is crucial for maintaining performance and reliability. Dust and moisture can:

  1. Cause Physical Damage: Dust particles can scratch the connector’s contact surfaces, while moisture can cause corrosion.
  2. Lead to Electrical Faults: Moisture can cause short circuits, especially in conductive environments.
  3. Affect Signal Quality: Dust and moisture can scatter or absorb signals, reducing strength and quality.

Preventive Measures

  1. Clean Equipment: Ensure connectors and equipment are clean before installation.
  2. Use Moisture Absorbers: In humid environments, use moisture absorbers or desiccants.
  3. Protective Covers: Use waterproof and dustproof covers to protect connectors.
  4. Regular Inspection: Regularly check and clean connectors to prevent dust accumulation and moisture infiltration.
