Fiber Optic Tools To Terminate Fiber Optic Cables

Essential Fiber Optic Tools for Terminating Fiber Optic Cables

Terminating fiber optic cables is a critical step in building reliable and high-performance optical networks. The termination process involves precisely connecting optical fibers to connectors, ensuring optimal signal transmission with minimal loss. To achieve successful terminations, using the right tools is essential.

Fiber Cleaver:

A fiber cleaver is a fundamental tool used to create a flat and clean endface on the fiber. It's a crucial step to achieve low insertion loss and back reflection. Fiber cleavers are available in different types, such as manual and automatic cleavers. They work by scoring the fiber and then applying controlled force to break it at the scored point, resulting in a precise cleave.

Fiber Stripping Tools:

Fiber stripping tools are used to remove the outer coatings and layers of a fiber optic cable, exposing the bare fiber. They ensure that the fiber is ready for the termination process. Different layers need to be stripped, including the outer jacket, buffer, and cladding, leaving only the core exposed. Stripping tools come in various designs, including adjustable and preset models, to accommodate different cable diameters.

Fiber Cleaning Supplies:

Properly cleaned fiber endfaces are essential for successful terminations. Dust, oils, and contaminants can lead to increased signal loss. Cleaning supplies include lint-free wipes and isopropyl alcohol. Cleaning sticks and cleaning pens are also available, designed to clean the connector endface and eliminate particles that might affect signal quality.

Epoxy and Adhesive Dispensing Tools (if applicable):

Some connector types require adhesive to secure the fiber within the connector. Epoxy and adhesive dispensing tools are used to apply the adhesive accurately and in controlled amounts. Precision is crucial to prevent excess adhesive from obstructing the fiber's core or causing signal degradation.

Connector Polishing Tools:

Though not always required for all connector types, connector polishing tools are used to achieve a smooth and precise endface on connectors that involve polishing. Polishing ensures low return loss and consistent signal transmission. Polishing tools include polishing films, lapping plates, and polishing machines.

Fiber Microscope:

A fiber microscope, also known as an inspection microscope, is used to examine the quality of the fiber endface and connector after cleaving and termination. It helps technicians detect any imperfections, contamination, or scratches that might negatively impact signal quality. High-magnification microscopes provide clear visualization for thorough inspection.

Fiber Optic Connectors:

Choosing the appropriate fiber optic connectors for your specific application is crucial. Different connectors are designed for various environments, cable types, and connector styles. Common connector types include SC, LC, ST, and MTP/MPO connectors. Make sure to select connectors that match your project's requirements.

Fiber Optic Termination Kit:

Termination kits often include a combination of the tools mentioned above. These kits are designed to provide technicians with a comprehensive set of tools required for various termination processes. They can be especially useful for those new to fiber optic termination, as they ensure that all necessary tools are readily available.

Fiber Optic Polishing Film and Pucks:

Polishing films and pucks are used for connectors that require polishing, such as epoxy-polish connectors. The films are attached to a polishing puck, which is used to evenly distribute pressure and achieve a consistent and smooth endface on the connector.

Heat Shrink Tubing and Heat Guns:

Heat shrink tubing is used to provide strain relief and protection to connectors and splices. It shrinks when heat is applied, creating a secure and protective layer around the termination point. A heat gun is used to apply controlled heat to the tubing, causing it to shrink and conform to the connector.

Polishing Machine (optional):

For high-volume termination projects, a polishing machine can streamline the polishing process. These machines provide consistent pressure and motion, resulting in uniform endfaces across multiple connectors.

Fiber Optic Test Equipment:

While not strictly a termination tool, fiber optic test equipment, such as power meters, light sources, and OTDRs, are essential for verifying the quality of terminations. These tools are used to measure insertion loss, return loss, and overall signal quality, ensuring that terminations meet performance standards.

Terminating fiber optic cables requires precision, attention to detail, and the use of appropriate tools. The tools mentioned above play a vital role in ensuring that terminations are successful, reliable, and capable of delivering optimal signal transmission. By investing in high-quality tools and following best practices, technicians can achieve consistent and high-performance fiber optic terminations, contributing to the overall efficiency and reliability of optical networks.
