Before you start installing fiber optic cables, you need to plan your route and determine the length, location, and type of cables you will need. You should also consider the environmental factors, such as temperature, humidity, dust, and vibration, that may affect your cables and choose the appropriate cable design and protection. Additionally, you should check the local codes and regulations for fiber optic cable installation and follow the safety guidelines to avoid hazards such as electric shock, fire, or eye damage.
To install and splice fiber optic cables, you will need some specific tools and equipment, such as fiber optic cable strippers, cleavers, splicers, connectors, testers, and cleaners. You should make sure that your tools and equipment are clean, calibrated, and in good working condition before you use them. You should also wear protective gear, such as gloves, goggles, and masks, to prevent injuries from sharp fiber ends or dust particles. Furthermore, you should have a clean and well-lit work area where you can handle your cables and splices with care and precision.
When you install your fiber optic cables, you should follow the manufacturer's instructions and specifications for bending radius, pulling tension, and cable support. You should avoid exceeding the maximum bending radius or pulling tension of your cables, as this may cause damage or signal loss. You should also secure your cables with proper cable supports, such as clamps, ties, or trays, to prevent sagging, kinking, or twisting. Moreover, you should label your cables and splices clearly and accurately to facilitate identification and troubleshooting.
There are two main methods for splicing fiber optic cables: fusion splicing and mechanical splicing. Fusion splicing involves using heat to melt and join the fiber ends together, creating a permanent and low-loss connection. Mechanical splicing involves using a special device to align and hold the fiber ends together, creating a temporary and higher-loss connection. The choice of splicing method depends on several factors, such as cost, time, quality, and reliability. Generally, fusion splicing is preferred for long-distance or outdoor applications, while mechanical splicing is suitable for short-distance or indoor applications.
Careful and accurate splicing is essential when joining fiber optic cables, regardless of whether you use fusion splicing or mechanical splicing. To ensure a good connection, you should strip the cable jacket and buffer coating to expose the bare fiber, then clean it with alcohol and lint-free wipes to remove any dirt or grease. You should cleave the fiber with a cleaver to create a smooth and perpendicular end face, followed by inserting the fiber into the splicer or the mechanical splice device and aligning the fiber ends with the help of a magnifier or a monitor. Once that is done, activate the splicer or the mechanical splice device to join the fiber ends together. Finally, check the splice quality and loss with a tester or a microscope, record the results, and protect the splice with a heat-shrink tube or a splice protector.
After you install and splice your fiber optic cables, you need to test and troubleshoot them to verify their functionality and performance. You should use a light source and a power meter to measure the optical power and loss of your cables and splices. You should also use an optical time domain reflectometer (OTDR) to locate any faults or defects along your cables and splices. If you find any problems or errors, you should identify the cause and fix it as soon as possible. You should also document your test results and keep a record of your cable installation and splicing.
