Fiber Optic Termination

Here is the English translation of the provided text: ```html

Fiber optic termination refers to terminating the end of a fiber cable with a connector in areas where fiber cables are used. The termination, which can also be expressed as making it ready for use, is likely necessary for every cable.

For fiber cross-connection, termination is crucial in signal distribution of the light wave, and it needs to be done meticulously. This ensures prevention of contamination and interference. Moreover, proper termination, preventing light loss, contributes to achieving the desired efficiency.

Considering the importance of fiber optic termination mentioned above, it is necessary to perform termination with the correct methods. Otherwise, the result obtained will not meet your needs. So, what kind of methods can be used during termination?

Fiber Optic Termination Methods

There are two methods for fiber optic termination. When the correct light, low light loss, and successful reflection are achieved, both methods meet expectations. In fiber optic termination, where environmental pollutants are at a minimum, maximum efficiency results in the best physical conditions. Therefore, the physical conditions must be optimal in both methods described below!

Fiber Optic Termination Method with Connector

Fiber optic connectors are designed for multiple uses. Therefore, the connection and disconnection process can be done multiple times without affecting optical performance. Termination, which needs to be done step by step, can achieve flawless results with the right method. Here are the steps to follow in termination with a connector:

• After removing the outer coating, buffer, and sheath, and removing the excess aramid yarn, the fiber optic cable is prepared for termination.
• Use a fiber cleaver to strip the fiber. Use the cutter carefully to prevent breakage and avoid balloon formation.
• Bend and break the fiber using a scribe tongue.
• After the breaking process, make sure the division is square, and there are no chips in the fiber.
• Measure the bare fiber using appropriate equipment. Evaluate whether the correct length is available. Having the bare fiber too long or too short will not yield accurate results, so you must achieve the appropriate length.
• Clean the fiber using cleaners without lint and with a 90% isopropyl alcohol solution. A higher alcohol concentration will not cause problems.
• After cleaning the fiber, insert it into the connector and bend the connector over the buffer.

By following this method, you will complete the termination process meticulously. If there is a step you missed or did not perform carefully in termination, you will not achieve the desired result from the fiber optic cable.

Fiber Optic Termination with Splice Device

Terminating with a splice device is not always the preferred option. Therefore, it is chosen when cables are long, or buried cables are accidentally cut. During splicing, you can choose between fusion splicing and mechanical splice location as two alternatives. Fusion splicing, which is a frequently used option, is detailed step by step below:

• In the preparation process for fusion, the cables are cleaned to ensure that the splicing process takes place healthily. If adequate cleaning is not done here, the splicing process will not yield healthy results.
• Smooth and perpendicular end face mirrors are preferred by carving and cutting methods during the carving and cutting process.
• In this alignment and heating stage, the fusion splicer must first be aligned correctly. When alignment is achieved, the ends of the fibers are melted by heating, using an electrical spring to prevent breakage.
• Since the tensile strength is between 0.5 and 1.5 lbs, precautions should be taken against excessive bending and pulling. Extra precautions should be taken at this point to increase the quality of the termination.

Desired results are achieved with fiber optic termination. It is essential to seek expert support for termination to facilitate the use of fiber optic cables. Otherwise, even if the use is possible, the desired efficiency cannot be achieved.
