Fiber optic cable has revolutionized the telecommunication sector worldwide. This type of cable is also known as optical fiber cable or fiber cable in Bangladesh. Optical fiber cable essentially transmits data at high speed using light energy through thin glass. Fiber cable has gained immense popularity in Bangladesh as it provides high-speed reliable data transfer, video streaming, voice communication, and other online services to homes, offices, and businesses. Currently, various popular brand including Unicore, Usha Mart, Level One, and Detech offers optical fiber cable at affordable price in BD.
Why use fiber optic cable?
1. Fiber optic cable can be used to transmit data over long distances at high speeds. Therefore, optical fiber cable is suitable for fast transfer in video streaming, online gaming, and cloud computing.
2. Fiber optic cable has much higher bandwidth capacity than copper cable. As a result, it transfers data at speeds higher than the gigabyte range.
3. Fiber optic cable has meager signal loss rates for data transfer over long distances. As a result, data can be easily transferred over long-distance network connections such as from one country to another or from one continent to another under the sea with fiber cable.
4. Fiber optic cable is generally immune to electromagnetic interference (EMI) and radio frequency interference (RFI). Because this type of cable transmits data using optical signals instead of electrical signals.
5. Optical fiber cable is usually enclosed in four layers including core, cladding, buffer, and jacket, so it is not easily damaged by environmental heat, pressure, etc.
6. Fiber cable is generally light in weight and can be easily transported anywhere as needed.
7. Fiber optic cable has advanced security measures for data transmission. As a result, sensitive and confidential information can be shared securely.
What type of fiber optic cable is available in Bangladesh?
Optical fiber cable is mainly divided into two categories based on the method of light transfer
Single-Mode Fiber: It is usually made of small-sized cores. Single-mode fiber has a core diameter of 8-10 microns Laser light is used to transmit a light signal through this type of fiber cable Laser light has a wavelength of 1,300 to 1,550 nanometers This type of fiber cable is used in various business establishments like university campuses, telephone companies.
Multi-Mode Fiber: Optical fiber with a large core is called multimode fiber. The core diameter of such cable is 50-100 microns larger than that of a single-mode fiber core. Multimode fiber uses infrared light for data transfer Infrared light has a wavelength of 850 to 1,300 nanometers This type of cable is suitable for data transfer over short distances. Moreover, data and audio/video can be transferred over local area networks with multimode optical fiber cable.
Optical fiber cable is divided into two categories based on the material they are made of:
Glass Fiber: This type of fiber cable uses high-quality glass fiber for fast data transfer through light energy.
Plastic Optical Fiber: In this type of cable, transparent thermoplastic called polymethylmethacrylate is used as the main material for fast data transfer through light energy.
Also, depending on the refractive index, optical fiber is divided into two type:
Step Index Fiber: This type of fiber cable is made up of reflexion, index file, and single index uniform.
Graded Index Fiber: As the number of radicals in this type of optical fiber cable decreases, the reflectance index decreases.
What is the price of fiber optic cable in Bangladesh?
Fiber optic cable price in BD is Tk 14 per meter, which is 4 core fiber optic cable and all-weather resistant. Fiber cable price in Bangladesh generally varies depending on the brand, number of cores, frequency, light transfer method, cable type, and data transmission rate, among other factors. 6 core fiber optic cable costs 23 taka per meter in Bangladesh. Also, 8-core to modern 24-core multimode optical cable is available on a budget of Tk 65 to Tk 220 per meter.
What to consider before buying optical fiber?
- Optical fiber cable should be considered according to the distance required for data transfer in homes, offices, or businesses.
- Fiber optic cable should be checked according to bandwidth requirements. As a result, the network used will help provide high-speed bandwidth in the future.
- When purchasing fiber cable, one must consider the security measures for data transfer.
- When buying optical fiber cable, it is necessary to check whether the cable size is compatible with the devices used, such as routers, servers, and switches, and whether it can be installed easily.
- Also, when buying fiber cable, check whether the cable will be suitable for long-term use.
Precautions to be taken while using fiber optic cable
- Because the cable inside the optical fiber is delicate, a splicing machine must be used for cable cutting in network connections.
- Protective gloves and safety glasses must be used when making connections to fiber optic cable networks.
- Fiber optic cable should not be bent beyond the bend radius to prevent signal loss.
- To prevent fiber cable breakage, excessive stress cannot be applied to the cable.
- The connection point of the optical fiber cable should not be damaged easily so the connection point should be well covered with a box. As a result, dust will be protected from sand or water.
- Also, fiber optic cable connections must be operated by a skilled technician.
