KELUSHI Fiber Optic Mechanical Splice FTTH Fast Connector Adapter

1. Introduction

The KELUSHI Fiber Optic Mechanical Splice FTTH Fast Connector Adapter is designed for quick and reliable cold connections of fiber optic cables, particularly for Fiber To The Home (FTTH) butterfly cables. This connector utilizes a precision V-groove butt joint technology to achieve a secure splice between two prepared fiber pigtails or optical fibers without the need for fusion splicing equipment. It is suitable for both indoor and outdoor applications.

2. Product Overview

Each KELUSHI Fast Connector consists of several key components designed for efficient fiber splicing.

Figure 2: Labeled components of the KELUSHI Fiber Optic Mechanical Splice. The image identifies the 'Cap', 'Cold Connector' (main body), and 'Buckle' mechanisms.

• Cold Connector Body: The central part containing the precision V-groove for fiber alignment.
• Cap: A protective cover that secures the fiber ends within the connector body.
• Buckles: Locking mechanisms at each end that hold the fiber in place after insertion.

3. Setup and Installation

Proper preparation of the fiber optic cable is crucial for successful splicing and minimal signal loss. Follow these steps carefully:

3.1 Required Tools (Not Included)

• Fiber Optic Stripper (for removing outer jackets and coatings)
• Fiber Cleaver (for precise, perpendicular fiber end-face preparation)
• Isopropyl Alcohol Wipes (for cleaning bare fiber)
• Optical Power Meter (optional, for verifying connection quality)

3.2 Fiber Preparation Steps

1. Strip the Fiber: Using a fiber optic stripper, carefully remove the outer jacket and buffer coating from the fiber optic cable to expose the bare fiber. Ensure all layers are removed without damaging the glass core.
2. Clean the Fiber: Gently wipe the exposed bare fiber with an isopropyl alcohol wipe to remove any contaminants. Allow it to air dry completely.
3. Cleave the Fiber: Place the cleaned bare fiber into a fiber cleaver. Perform a precise cleave to achieve a clean, flat, and perpendicular end-face. The recommended cleave length is approximately 13-14 mm. An improper cleave is a common cause of high signal loss.

3.3 Connector Assembly Steps

1. Open the Connector: Gently open the cap and buckles on both ends of the mechanical splice connector.
2. Insert First Fiber: Carefully insert one of the prepared fiber ends into one side of the connector's V-groove. Push the fiber gently until it reaches the internal stop or until you feel slight resistance.
3. Secure First Fiber: Close the buckle on the side where the first fiber was inserted to secure it in place.
4. Insert Second Fiber: Insert the second prepared fiber end into the opposite side of the connector's V-groove. Push it gently until it butts against the first fiber within the V-groove. You may observe a slight bowing of the first fiber if using a visual fault locator.
5. Secure Second Fiber: Close the buckle on the second side to secure the second fiber.
6. Close Cap: Close the main cap of the connector to provide additional protection and stability.

4. Operating Instructions

Once the fiber optic mechanical splice is correctly installed, it functions as a passive connection point. No further operational steps are required. Ensure the connected cable is not subjected to excessive bending, pulling, or crushing forces, which could compromise the splice integrity and signal transmission.

5. Maintenance

The KELUSHI Fiber Optic Mechanical Splice requires minimal maintenance. To ensure long-term performance:

• Keep the connector clean and free from dust and debris, especially before installation.
• Avoid exposing the connector to extreme temperatures or humidity beyond its specified operating environment.
• Periodically inspect the connection point for any physical damage or signs of stress on the cable.

6. Troubleshooting

If you experience issues with your fiber optic connection after installing the mechanical splice, consider the following:

6.1 No Light Transmission or High Signal Loss

• Fiber Preparation: The most common cause of issues is improper fiber preparation.
• Ensure the fiber ends are perfectly clean before insertion. Any dust or residue can cause significant loss.
• Verify the fiber cleave quality. The end-face must be flat, smooth, and perpendicular to the fiber axis.
• Check the cleave length. An incorrect length (e.g., too short) may prevent proper seating in the V-groove.
• Fiber Insertion:
• Confirm that both fibers are fully inserted into the V-groove and are butted against each other.
• Ensure the buckles are securely closed to maintain fiber position.
• Connector Damage: Inspect the connector for any visible damage to the V-groove or locking mechanisms.
