What is the difference between traditional optical fiber and air-blown optical fiber cabling

Most of the network cabling is installed using the traditional optical fiber system; in this case, it is necessary to carry out suitable optical fiber installation using the design solutions that have been discussed. ZR Cable makes a comprehensive comparison between traditional optical fiber and air-blown optical fiber cabling.

Comprehensive comparison of traditional optical fiber and air-blown optical fiber cabling

The installation method of "air-blown optical fiber" was actually developed and designed so many years ago at the end of the 1980s. The basic principle of the air-blown optical fiber system is to install a set of pipelines in the middle of the part where the optical fiber will be or will go, also known as "do the hose" or "micro-pipe". When it is necessary to lay optical fibers in the middle of the two points of the Internet, according to the special type of installer, the optical fibers are "blown" into the pipeline, and then the optical fibers are connected with the connectors.

The basic principle of traditional fiber optic installation is that the fiber optic cable is embedded in a hose or wireway; it is then dragged from one point to another. Even a medium-to-large fiber optic cable with 288 fibers cannot easily exceed 1 foot in straight length, which is much smaller than the multi-pipe construction used in air-blown fiber optic systems. After the optical cable is pulled, the optical fiber is laid, and finally the hardware environment is received. Routing protocol damage can be identified and fiber can be delivered. Since the hardware environment is not used in other areas except on both sides of the optical cable, the raw material cost of this system is lower than that of the air-blown optical fiber system. The design scheme is fixed, which is conducive to long-term maintenance, and the system can be moved or changed without asking the installation staff to go home and carry out new upgrades. And can install single-mode fiber, showing the way to upgrade in the future.

The air-blown fiber optic system in the AN natural environment claims to have a lower cost advantage, which cannot be compared with the traditional fiber optic cabling system. I've heard that air-blown fiber systems save time and space; in addition, they can improve product planning and coordination. However, other challenges also need to be considered, such as compliance with regulations, cost, manufacturer compatibility open to the outside world, quality and toughness, scale of operation and ease of application. Whether you choose an air-blown fiber optic system or a traditional installation system fiber optic cable, there will often be unexpected needs in the future.

The coordination capabilities in both conventional and air-blown fiber optic systems immediately jeopardize the cost of the overall system. With the air-blown fiber optic system, if the pipeline is not shown between the two points, the fiber cannot be installed. As with traditional fiber optic systems, new fibers must be installed without fiber. However, as mentioned in the Design Schemes chapter, if as part of a traditional cabling design scheme, a heavy-duty routing protocol is installed; then, the application patch or network switch can easily handle the various routers, loops required topology and additional fibers.

The air-blown optical fiber system is selected, and the installation conditions are the straight diameter of the optical fiber product, the straight diameter of the hose, the friction index value of the applied raw material, the total gas flow, the standard air pressure, the total number of vertical rises, the hose is blocked, and the hose is intermittent. and other main parameters. This element can create a systemic risk of mounting pitch and aspect ratio. And, if future changes require fiber optics to be installed in areas without hoses or pipes, the installation of hose systems in buildings will become a major obstacle. After a period of time, the hose or piping system will be subjected to severe treatment.

Typical home building applications involve the installation of additional fiber optic cables, the installation of basic business processes on utilities (switching power supplies, alarms, sprinklers, HVAC, horns, air compression, in-room water and drainage, etc.) The current equipment causes risky work. If the tubing looks durable, it has to be durable. The maintenance staff will feel that the durability level of the air-blown fiber optic line will be higher than it actually is, and will solve according to this feeling. It should be noted that the air blowing program process is very sensitive to ambient humidity and temperature, and the air blowing characteristics in different natural environments will be very different; however, the traditional wiring system is extremely stable and tough; it can be integrated into a large temperature Shifting categories and various environmental standards.

Any cost or time advantage is quickly dissipated if the line is blocked, cracked or the cyclone is not detailed. Also, there will always be situations where no piping is installed in areas that need to be added to the system in the future. Although; the cost of installing empty pipes will be relatively low, but the cost of fiber and air blowing is very high, so the final installation cost is higher than that of traditional fiber systems (up to 50% apart).

In accents, statistics or video communications, trustworthiness is one of the most critical aspects of wireless communication systems. In order to ensure reliability, it will be safer to use tried and tested optical cable products that meet national standards. This specification includes not only fiber optic specifications, but also mechanical equipment. and natural environment index values, such as fire safety and smoke regulations. Optical cable and hose products must be able to bear the rough expansion, loading, unloading and handling in the whole process of installation; and non-general building applications. Routine building maintenance, excessive congestion in connecting areas, and moving or moving utilities are all potential difficulties for future installation teams to remove or connect fiber optic cables to blow in large amounts of fiber.

Commodities that do not meet national standards or have not been tested have a certain level of risk and will lead to system reliability, and combined use will lead to a new pattern of single sources. Air Blown Fiber is an alternative image commodity that is still not generally accepted by LAN app stores. This is a unique method, and current version numbers use different or inappropriate components and methods. This limits the options available today and in the future.

System consistency eventually becomes a key practical requirement. A system that seems worthwhile considering future conditions can create difficulties at the level of loan guarantees and obligations. Who takes responsibility for unmaintained expectations discovered two years later in the original work? What is the level of credibility? What is the danger to trends? How to identify the real problem and who will pay for it? For the construction of line infrastructure, this kind of problem can be designed in advance.

Traditional fiber optic cable designs and cabling sound card rack hardware allow introductions from the very middle section and allow fiber to "pass through" the middle point. Connectors and RF connectors are only used when a fiber spotting is required or for the better. It is unrealistic to see that the middle section of the optical fiber product containing plastic coating that has never been in compliance with the regulations. In fact, breaking in the middle will damage the pneumatic consistency of the air-blown fiber optic line. To enjoy the simplicity of air-blown fiber installation, it is essential to establish a return route from the host room to each termination point; otherwise, air-blown equipment must be installed in several locations. From a convergence and interconnection perspective, there are no significant advantages to air-blown fiber optic systems.

The termination of the air-blown optical cable is no different from that of the traditional optical cable; however, more attention should be paid to the bending half warp, so that the tube bundle has a good air-blown environment (too tight bending will reduce the air-blown fiber core spacing).

Fiber maintenance in the pipeline is present, and there is no internal compressive strength prefabricated components, etc. It does not have the same level of tensile strength, or endurance, as traditional fiber optic cables.

After the wiring is carried out and adjusted, the traditional wiring system is basically maintenance-free. The port number or mobile terminal can be added according to the needs, and the actual operation is not likely to suffer great harm; however, the air-blown fiber optic system needs to assign installation personnel to the site during the operation period.

The maintenance of the air-blown optical fiber distribution system requires accurate pipeline distribution records, and requires various special optical cables to be integrated and inserted into the hardware environment, air-blown equipment and its well-trained installation staff. Refrigerated compressor air needs to be used to blow the fiber, which will be harmful to physical and mental health and safety, and will not be used for future air blowing in manufacturing or work environments. A point that should be taken into account with all air-blown fiber optic networks is gas blockage at the junction of the interior or outside of the building population, as well as water blockage from the outside and underground paving.

Air-blown fiber is a practical way to install fiber optic cables inside buildings. But even under idealized operating standards, system reliability is extremely important. Therefore, it is proposed to use commodities that meet national standards. Many of the application common problems identified above make overall planning an air-blown fiber optic system just as difficult as planning a traditional cabling system. In the traditional wiring system, the Shenyu routing protocol design scheme can be simply integrated into the traditional wiring system; but in the air-blown optical fiber system, the Shenyu routing protocol will make the connection of the installation staff more and more complicated in the future.
