How Do You Terminate Fiber Optic Cable?
Terminating fiber optic cables is a crucial process that ensures the efficient and reliable transfer of data in communication networks. This process involves attaching a connector to the end of the fiber optic cable, enabling it to be plugged into network equipment or linked to other fiber optic cables. A proper termination is essential to maintain signal integrity and network performance. The process requires precision and care due to the delicate nature of fiber optic cables. There are different methods to terminate fiber optic cables, each suited for specific applications and requirements.
Regardless of the method used, there are a few basic steps involved in the termination of fiber optic cables. These steps ensure that the fibers are prepared and connected correctly for optimal performance.

Key Methods for Terminating Fiber Optic Cable
1. Connector Termination (Using Pre-Polished Connectors)
One of the most commonly used methods for fiber optic cable termination, particularly for field installations and repairs, is the connector termination method using pre-polished connectors. This method is favored for its speed and ease of use. The pre-polished connectors come with a pre-finished fiber stub, significantly reducing the time and effort required for installation.Key Steps for Connector Termination:
- Cable Preparation: The first step is to strip away the outer jacket and any protective layers of the fiber optic cable, exposing the bare fiber.
- Fiber Cleaning: It’s essential to clean the exposed fiber using isopropyl alcohol and lint-free wipes to remove dust and contaminants that can degrade the signal.
- Cleaving: A precision cleaver is used to create a clean, flat break at the end of the fiber. This is crucial to ensure proper alignment when connecting the fiber to the connector.
- Connector Insertion: The cleaved fiber is carefully inserted into the pre-polished connector. The pre-existing fiber stub and an index-matching gel help align the fiber.
- Crimping/Securing: After insertion, the connector is crimped or secured as per the manufacturer's instructions to ensure a stable connection.
Advantages:
- Fast and Easy: The process is relatively fast compared to other methods, making it ideal for field applications.
- Less Specialized Equipment: Unlike fusion splicing, this method doesn’t require expensive equipment, making it more cost-effective for certain installations.
Disadvantages:
- Higher Insertion Loss: While effective, connector termination may result in slightly higher insertion loss compared to fusion splicing.
2. Fusion Splicing (With Pigtails)
Fusion splicing involves splicing a short length of fiber optic cable (pigtail) onto the field cable. This method provides the lowest insertion loss and highest quality connection, making it ideal for critical applications where performance is a top priority.Key Steps for Fusion Splicing:
- Cable and Pigtail Preparation: Both the field cable and the pigtail must be prepared by removing their outer jackets and cleaning the fiber ends.
- Fusion Splicing: A fusion splicer is used to align the fiber ends precisely. The splicer uses an electric arc to fuse the fibers together, creating a seamless connection.
- Protection: A protective sleeve is placed over the splice to reinforce the connection and protect it from environmental factors.
- Connector Connection: The pigtail, which already has a connector attached, is then connected to the equipment or patch panel.
Advantages:
- Low Insertion Loss: Fusion splicing provides the most reliable and low-loss connection, which is ideal for high-performance fiber optic networks.
- Highly Reliable: The fusion splice ensures a strong and durable connection, making it a preferred method for long-term installations.
Disadvantages:
- Requires Expensive Equipment: Fusion splicing demands a fusion splicer, which can be costly.
- Requires Skilled Technicians: The process requires specialized knowledge and experience, which can increase installation costs.
3. Epoxy and Polish Connectors
The epoxy and polish method is a traditional fiber optic termination technique that was widely used in the past. Though it has become less common for field installations, it is still used in specific scenarios where high precision and quality are required.Key Steps for Epoxy and Polish Connectors:
- Epoxy Application: Epoxy adhesive is applied to the inside of the connector, which will secure the fiber in place.
- Fiber Insertion: The prepared fiber is then inserted into the connector, ensuring proper alignment.
- Curing: The epoxy is allowed to cure, securing the fiber to the connector.
- Polishing: Once the epoxy has cured, the connector end is polished to achieve a smooth, clean surface for optimal signal transmission.
Advantages:
- High-Quality Connection: When done correctly, epoxy and polish can create very strong and reliable connections.
- Good for Specialized Applications: This method is suitable for applications requiring high precision and stability.
Disadvantages:
- Labor-Intensive: The process is time-consuming and requires high skill levels to achieve the best results.
- Not Ideal for Field Installations: Due to its complexity, this method is less commonly used for field installations today.
General Steps for Fiber Optic Termination
Regardless of the method used, there are a few basic steps involved in the termination of fiber optic cables. These steps ensure that the fibers are prepared and connected correctly for optimal performance.
1. Cable Preparation
The first step is to prepare the fiber optic cable by stripping off the outer jacket and protective layers. This exposes the glass fibers that will carry the data signals.2. Fiber Cleaning
After exposing the fiber, it’s crucial to clean it thoroughly using isopropyl alcohol and lint-free wipes. Dust and contaminants can degrade the performance of the fiber optic connection, so cleanliness is essential.3. Fiber Cleaving
Using a precision cleaver, the fiber ends are cut to create clean, flat surfaces. This ensures that the fiber will align correctly with the connector or other fibers during splicing.4. Fiber Alignment
Whether you are using connectors, fusion splicing, or epoxy, aligning the fiber ends precisely is crucial to ensure a stable connection and minimize signal loss.5. Fiber Connection
Once the fibers are aligned, the connection is made using the chosen termination method. Whether it’s through a connector, fusion splice, or epoxy and polish method, the fibers must be securely joined to ensure reliable performance.6. Testing the Connection
After termination, the connection should be tested using an optical loss test set (OLTS) or an optical time-domain reflectometer (OTDR) to ensure proper signal transmission and minimal loss.Important Safety Precautions
Working with fiber optic cables requires attention to safety to avoid injury or damage to the equipment. Some essential safety precautions include:- Wear Safety Glasses: Always wear safety glasses when handling fiber optic cables, as they can produce sharp glass shards when cut.
- Proper Disposal: Dispose of fiber scraps carefully, as they can be sharp and pose a risk of injury.
- Avoid Eye Exposure: Never look directly into the end of a fiber optic cable, as the laser light can damage your eyes.
- Handle with Care: Fiber optic cables are delicate and should be handled gently to avoid breakage or damage.
