Fibre optic cables are mechanically different from electrical cables, and fibre optic cable laying methods are also different when compared to laying methods of electrical cables. Fibre optic cables are brittle. fibre optic cable is a material with some elastic properties. Sharp bending, compressive, and tensile forces should be adequately protected for proper installation and trouble free operation of optical fibre cable. The proper installation methods can be learned from an optical fibre training institute.
The transmission characteristics of an optical fibre cable are determined by the installation method as well as the quality of the accessories and associated materials used. Optical fibre cable installation is a specialized skill. Optical fibre cable laying is strictly supervised by the trained professionals. And to get professional training you need to enrol yourself in the best optical fibre training institute in India. Before knowing more about the best institute, let’s first understand the different types of Fibre optic cable laying methods.
What are the common methods for laying fibre optic cables?
Ducting and trenching are used to lay underground optical fibre cables. Construction equipment such as directional drills, micro trenchers, vacuum excavators, mud recyclers, and skid steers are commonly used for ducting and trenching.
In countries with multiple operators, trench specifications are typically defined by local authorities and could be specified for each operator. Trenching requires careful control to ensure that the trench floor is uniform and free of kinks, and also that trenches do not have major bends.
Ducts are installed in the trenches, and fibre is blown through them with specialized fibre blowers that use either water or air. Blowers in Air Assisted Fiber Blowing use compressed air to push fibre through ducts. It is common practice to lay conduits first, then draw inner ducts through the conduits, and finally blow fibers through the ducts. The most common conduit size is 4 inches (100mm), but 6 inch (150mm) conduits are also available. The inner duct is typically 1.25 inches in diameter. Proper fibre optic cable installation methods can be learned by joining an optical fibre cable training centre.
It is important to note that fibre optic cables should never take up more than 70% of available duct space. When 1 inch fibre cables are used, they take up 64% of a 1.25 inch duct. High Density Polyethylene is used to make ducts (HDPE). HDPE is a hard material that can withstand temperatures of up to 120°C and is resistant to alcohols, concentrated acids, and bases.
What is Mini Trenching?
Mini trenches are created on various surfaces using automated equipment. This technique can be used on asphalt-surfaced routes such as sidewalks and roads. The technique, however, is not suitable for soil that contains cobbles or gravel, or for sandy soil. This technique has a significant advantage over conventional cable-laying methods in that it is much faster to implement. The trench cross-section and depth will be determined by the number of ducts to be installed. The depth is typically between 30 and 40 cm, while the cross-section varies between 7 and 15 cm.
The three most common methods of mini trenching are:
- Semi Automated
- Fully Automated
When the fully automated method is used, trenching, ducting, backfill operations, and cleaning are all done at the same time. The operations are not performed at the same time when the standard and semi-automated methods are used. The automated training methods should be done with the help of a trained optical fibre technician who has got professional training from the best fibre optic training training centre.
What is Micro Trenching?
Micro-trenching is a fibre-laying technique that uses specialized machines to cut a narrow and shallow trench into a road’s surface, alongside the pavement where the curb and the tarmac meet, as opposed to traditional fibre laying techniques that require much larger trenches to be dug.
Micro trenching, unlike conventional trenching, creates a shallow trench in asphalt that is typically 2 cm wide and 30 cm deep. The grooves are then filled with special microtubes, which are usually made of cold asphalt. Following that, the fibres are blown into the tubes.Deep knowledge in all the engineering techniques in operating micro trenching machines can be learned by joining fibre optical training class run by a professional training institute.
What are Aerial Fiber Optic Cables?
Aerial fibre optic cables are installed in the same way that copper telecommunication cables are. However, it is critical to understand that the transmission characteristics of fibre are affected by compressive stress, tensile stress, and bends, making it essential to maintain cable sag within acceptable limits.
Galvanized Iron (GI) messenger or support wires provide support for fibers strung between GI or other suitable poles. There are two methods for lashing fibre optic cable: stationary lashing and moving reel lashing.
The cable is pulled into place using cable blocks in the Stationary method, whereas the Moving Reel method uses reel carrying vehicles along the entire route of the fibre. All Dielectric Self-Supporting (ADSS) cables are ideal for aerial installations. ADSS cables, as the name implies, do not require any supporting or messenger wires. Aerial cable laying methods can be learned by joining a fibre optic training course in a leading institute. This will help fibre optic technicians to get higher salaries and career growth.
What is Direct-Buried Cable?
This fibre laying technique entails using specialized equipment to make tiny incisions in any surface, including concrete and asphalt. The fibre cable is then laid with a protective covering, and the groove is filled with epoxy. The protective covering shields the fibre from the tensile and compressive forces that fibers are prone to.
Fiber cable should always be buried beneath the maximum depth reached by agricultural equipment on farms.
On the other hand, the burial depth at highway and road crossings should be sufficient to prevent cables from being damaged during maintenance and road grading. These cables would typically be 12 inches deep. The proper cable burying methods can be learned by attending professional training in a fibre optic training institute in India. Professional training can increase the skills and a trained fibre optic technician can ensure career growth.
What is Horizontal Directional Drilling?
Horizontal Directional Drilling (HDD), also known as Directional boring, is a trenchless method for installing conduits, underground pipes, and cables.
A drilling rig launched from the surface is used to create a shallow arc along a predefined path for this type of installation. Because the impact on surrounding areas is minimal, this method is preferred when excavating or trenching is impractical. It can be used in a variety of soil conditions and jobs, such as landscape, road, and river crossings. Some cities will only grant Right-of-Way (ROW) permits for HDD-based cable laying.
The procedure is multi-staged, with the first step involving the construction of an entrance pit with a receiving hole. After drilling a pilot hole through the designed path, the hole is enlarged (reamed) with a larger cutting tool known as the back reamer. The size of the pipe to be pulled back through the hole determines the diameter of the reamer. The drill stem is then used to insert a casing pipe into the enlarged hole. Advanced HDD machines use a fully automatic gyro-based drilling mechanism.Operating HDD machines is a job that requires good analytical skills, these machines are very expensive and complicated too. HDD machine operation training courses are available with the best fibre optic training institute in India. After getting training the operator should undergo an internship with any contracting companies that undertake HDD cable laying contracts.
What is Submarine Optical Fiber Cable?
It is a cable laid on the sea bed between land-based stations to carry telecommunication signals across vast stretches of ocean. Individual optical fibre elements are typically coated with plastic layers and housed in a protective tube appropriate for the environment in which the cable will be deployed. Modern cables use optical fibre technology to transport digital data such as telephone, internet, and private data traffic.
Submarine fibre cables are classified into two types: unrepeatered and repeatered.
Submarine cables are highly reliable, especially when multiple paths are available in the event of a cable break. Submarine cables have a total carrying capacity of terabits per second, whereas satellites typically offer only 1,000 megabits per second and have higher latency. Submarine cable laying is a skilled job with very high salaries and perks, it can be learned from fibre optic training centres. There are many fibre optic training institutes in our country. Always join for fibre optic training Courses with internationally accepted course certificates.
