Wiring Comprehensive Comparison: The Traditional Optical Fiber Gas Chuiguang Xian - Wiring, Cables,
City Line system is the most comprehensive traditional fiber-optic systems installed; this case
, take advantage of the design method has been discussed in the appropriate optical fiber installation. The system has been numerous success stories prove feasible; reliable; stability; mature and outstanding.Recently another called "gas Chuiguang Xian" installation technology, in fact many years ago had developed in the late 80s had finished. Gas Chuiguang Qian system is to go in the will or may be installed between the location of fiber a group of Pipeline , Also known as "doing catheter" or "micro-channel." When the need for laying fiber-optic network between two points, through a dedicated fiber optic installer put the "blown" into the pipe, then use the connector to connect fiber.
Traditional fiber installation principle is: to be placed in conduit or trunking cable; and then drag from one point to another point. Even with 288 fiber optic cables of large diameter not more than 1 inch, than the gas Chuiguang Qian system structure used in multi-channel multi-smaller. After dragging a good optical cable, optical fiber also laid Well, finally received a hardware device. Determine the link loss, optical fiber can be put into use. Because in addition to the two ends of the cable, does not require hardware other places, so the material cost of the system than the system of low cost gas Chuiguang Xian. Design is fixed, contribute to long-term maintenance can be Mobile Or change the system, eliminates the need for installers to come back, a new upgrade. And single-mode fiber can be installed to provide future upgrade path.
LAN environment gas Chuiguang Qian system claimed to lower the cost advantages of traditional fiber optic cabling system can not be compared. It is said that the system can save gas Chuiguang Qian space and time; while also improving the system design and flexibility. However, other issues also need to consider, such as whether the standards, costs, opening up the vendor support, the quality and toughness, size and ease of use. Whether the choice system, or traditional gas Chuiguang Qian installation cable, in the future are likely to unexpected needs.
Traditional gas Chuiguang Qian system flexibility have direct impact on the cost of the whole system. Chui Guangqian system using gas, if not provided in the channel between two points, you can not install the fiber. If the traditional optical systems, optical fiber must not install a new fiber-optic. However, if the design of a chapter, if, as part of the design of traditional cabling; installed redundant link; then use the patch or the network Switch Can easily solve the needs of a variety of routing, loop topology, and additional fiber.
Using gas Chuiguang Qian system, the installation depends on the diameter of optical fiber products, vessel diameter, the use of the friction index, air flow, pressure, vertical rise in the number of catheter obstruction, catheter intermittent parameters. These factors can cause installation distance and high uncertainty. Moreover, if the future change, there is no need to place duct or pipe installed optical fiber, laying pipe in the building system will be severely hindered. After a period of time, duct or piping may have to undergo rigorous treatment. General Building applications involve the installation of additional cables, the utilities (power, alarm, sprinkler, HVAC, Speaker, compressed air, indoor water supply and drainage facilities, etc.) installed on conventional operations, and existing facilities may be dangerous operation. If the pipeline looks very durable, it must be very durable. Maintenance workers may think that the durability of pipeline gas Chuiguang Qian than it actually may be higher durability, and its processing in accordance with this feeling. It is noteworthy that blowing procedures are sensitive to humidity and temperature, air blown under different environmental performance will vary; However, traditional cabling system is extremely stable and robust on; can adapt to large temperature range and kinds of environmental conditions.
If the pipeline is blocked, broken, or air is not complete, any cost or time advantage will soon disappear. Moreover, the need to be added next in the system where the situation is not installed on the pipeline will always happen. Although; install air piping may be low cost, but costs are high fiber and air blowing, so the final installation costs than conventional optical system (a maximum difference of 50%).
The voice, data or video Communicate , The reliability of the communication system provides the most important aspect. To ensure reliability, the use of tested, industry-standard fiber optic cable products will be more secure. These standards include not only optical standards, including machinery. And environmental indicators, such as fire and smoke requirements. Cable and duct products to be able to withstand rough installation process extension handling; and non-general use inside the building. Routine building maintenance, access to the region of overcrowding, movement or displacement of public facilities will be installed on the next team removed or access to blowing more fiber optic cable causing potential difficulties. Use does not meet industry standards, or test the products without a certain degree of risk the expense of reliability, with possible single-source situation. Gas Chuiguang Xian is an alternative product, the market has not been widely accepted LAN applications. It is a proprietary technology, the existing version of the use of different or incompatible components and technology. This limits the options now and in the future.
Integrity of the system will eventually become an important practical requirement. If full account of the circumstances and that the future system will produce cost-effective security and accountability problems. Who completed a few years after the initial discovery, unrealized expectations for? What is the degree of reliability? What is the impact of its development? How to determine the real cause of the problem, who will bear the cost? Traditional cabling infrastructure, these problems can be designed to advance.
Traditional cable design and wiring rack hardware to allow the introduction of the middle segment, and allows optical fiber, "flow through" the middle point. Optical fiber only as needed to facilitate the extraction point, or only use joints and connectors. Never meet the standards, with plastic Coating Fiber-optic products out of the middle section appears to be impractical for some. In fact, from the middle disconnect could undermine the aerodynamic integrity of the pipeline gas Chuiguang Xian. To enjoy the ease of installation of gas Chuiguang Qian advantage, it essential to each room termination from the endpoint to create a homing line; Otherwise, it must be installed in multiple locations blowing equipment. From the perspective of integration and interconnection, gas Chuiguang Qian system is not a clear advantage.
Air blown optical fiber cable termination and no different from the traditional; but need more
