How to check the quality of fiber optic cable?

As we all know, the quality of the transmission medium in integrated wiring is very important to the entire project. This is not only the service life of the integrated wiring project, but also the guarantee of its quality and performance. People are often keen to use optical fiber cables as long-distance transmission media because optical fiber cables have the advantages of strong resistance to electromagnetic interference, low signal attenuation, large capacity, light weight, small size, and long transmission distance.Tip 1. Choose fiber optic cables based on materialsMaterials used in optical cables and production processes The selection of optical cable materials is key to the service life of optical cables. The manufacturing process is an important link that affects the quality of optical cables. Products with stable processes and excellent quality are basically not included in the optical fiber additional loss in the entire process of optical cable production. ≤0.01dB/km is the basic data to measure the manufacturer’s optical cable manufacturing process level. .Tip 2: Choose fiber optic cables based on the number of coresThe structures of different types of optical cables can be selected according to the number of cores, which can be divided into central bundle tube type, layer strand type, skeleton type and ribbon type. The structures are different for different uses. Users can put forward corresponding requirements according to the line conditions. Generally, those with less than 12 cores adopt the central bundled tube type. The central bundled tube type has a simple process and low cost, and is competitive in overhead laying or branch trunk line networks with good pipeline protection. Layer-stranded optical cables use centrally placed steel strands or single-stranded optical cables. Reinforced by a steel wire, SZ continuous synthetic cable is used, and the number of fibers in the cable can reach 144 cores.Tip 3: Choose fiber optic cables based on usageChoose the corresponding optical cable according to the purpose. Depending on the purpose, optical cables can be divided into aerial optical cables, direct buried optical cables, submarine optical cables and metal-free optical cables. Aerial optical cables require high strength and a small temperature difference coefficient; direct-buried optical cables require good burial resistance, pressure resistance, moisture resistance, moisture resistance, and chemical erosion resistance; pipeline optical cables and submarine optical cables require water pressure resistance, tension resistance, and good waterproof properties; none Metal optical cables can be erected together with high-voltage lines. The insulation must be good. Although there is no iron core to strengthen the cable, it must have a certain tensile strength.Fiber hope fiber optic cable and patch cord manufacturers can provide high-quality fiber optic cables, fiber patch cords, fiber optic cable clamp, welcome to inquiry!

What are the frequently asked questions about Optical Communications?

1. What is the testing principle of optical time domain reflectometer (OTDR)? What is the function?Answer: OTDR is based on the principle of backscattering and Fresnel reflection of light. It uses the backscattered light generated when light propagates in the optical fiber to obtain attenuation information. It can be used to measure fiber attenuation, joint loss, fiber fault point location and Understanding the loss distribution along the length of optical fiber is an indispensable tool in optical cable construction, maintenance and monitoring. Its main index parameters include: dynamic range, sensitivity, resolution, measurement time and blind zone, etc.2. What does “1310nm” or “1550nm” in common light test instruments refer to?Answer: It refers to the wavelength of the optical signal. The wavelength range used in optical fiber communication is in the near-infrared region, with wavelengths between 800nm and 1700nm. It is often divided into short wavelength band and long wavelength band, the former refers to the wavelength of 850nm, and the latter refers to 1310nm and 1550nm.The working wavelength of optical fiber communication is in the near-infrared region, and the bands are:O-band: 1260nm to 1310nmE-band: 1360nm to 1460nmS-band: 1460nm to 1530nmC-band: 1535nm to 1565nmL band: 1565nm to 1625nmU-band: 1640nm to 1675nmSingle-mode fiber usually operates at 1310nm, 1550nm and 1625nm.3. Among currently available commercial optical fibers, what wavelength of light has the smallest dispersion? What wavelength of light has the least loss?Answer: Light with a wavelength of 1310nm has minimum dispersion, and light with a wavelength of 1550nm has minimum loss.4. How are optical fibers classified according to the different modes of light waves transmitted in optical fibers?Answer: It can be divided into single-mode fiber and multi-mode fiber. The core diameter of single-mode optical fiber is approximately between 1 and 10 μm. At a given operating wavelength, it only transmits a single fundamental mode and is suitable for large-capacity long-distance communication systems. Multimode optical fiber can transmit multiple modes of light waves, with a core diameter of approximately 50 to 60 μm, and its transmission performance is worse than that of single-mode optical fiber.5. Optical fiber connectors have two most basic performance parameters. What are they?Answer: Optical fiber connectors are commonly known as unions. For the optical performance requirements of single-fiber connectors, the focus is on the two most basic performance parameters of insertion loss and return loss.6. How many types of commonly used optical fiber connectors are there?Answer: According to different classification methods, fiber optic connectors can be divided into different types.According to different transmission media, they can be divided into single-mode optical fiber connectors and multi-mode optical fiber connectors;According to different structures, it can be divided into various types such as FC, SC, ST, D4, DIN, Biconic, MU, LC, MT, etc.; according to the pin end face of the connector, it can be divided into FC, PC (UPC) and APC.Commonly used optical fiber connectors: FC/PC type optical fiber connector, SC type optical fiber connector, LC type optical fiber connector.7. What are the connection devices for optical fiber?1) Optical fiber splicing2) Optical fiber connectorfiber optic adapterPC/UPC/APC fiber cross sectionThe cross-sections of fiber optic connectors should be divided into PC, UPC, and APC.PC and UPC are optical fiber microsphere end faces that are parallel to the end face of the ceramic body. The industry standard return losses are -35dB and -50dB respectively.The APC section has an 8-degree tilt angle. In order to reduce reflections, the industry standard return loss is -60dB.8. What does an optocoupler mean?Fiber optic coupler (Coupler), also known as splitter (Splitter), is a component that splits optical signals from one optical fiber to multiple optical fibers.Couplers are bidirectional passive devices, and their basic forms include tree and star.9.

The armor is attached to the inner jacket of the fiber optic cable.6. What are the causes of fiber attenuation?Answer: The optical power in the optical fiber gradually decreases along the vertical axis. Optical power reduction is related to wavelength. In optical fiber links, the main reasons for optical power reduction are scattering, absorption, and optical power loss caused by connectors and fusion splices. The unit of attenuation is dB.Causes: There are many reasons for fiber attenuation, mainly including: absorption attenuation, including impurity absorption and intrinsic absorption; scattering attenuation, including linear scattering, nonlinear scattering and structurally incomplete scattering, etc.; other attenuation, including micro-bending attenuation, etc. . The most important of these is attenuation caused by impurity absorption.7. What is the bandwidth of optical fiber related to?Answer: The bandwidth of optical fiber refers to the modulation frequency when the amplitude of optical power is reduced by 50% or 3dB from the amplitude of zero frequency in the transfer function of optical fiber.
