the trunk cable in the park. This article focuses on a type of testing method that is widely used to verify the performance of optical fiber cabling systems. Purpose of Reference Value Setting The types of optical fiber connectors for each project are different, and the models of the tested links are also different. To increase the flexibility and operability of the test and reduce the wear and tear of the light source and optical power meter ports during the measurement process, an important s

Two, why should fluke use that "expensive" adapter Some manufacturers have introduced the Integrated Cabling System test scheme without adapters, and the principle is to set reference values in reference to the optical fiber integrated wiring system test method. Theoretically, it does have its own uni

cable factory, has introduced a number of production lines for a number of foreign brand products for domestic fixed-point OEM production, in the IT industry jargon, this is called OEM. I have been invited to visit some of these plants, found that many foreign brands of twisted-pair (including five, five and six categories) are in this production, the same production line made of products, brand different, the price difference is also very large, OEM products are usually the original brand prod

materials and printing clearly, and in most cases there are anti-counterfeit labels outside the carton. 2. Work on twisted pair case. The insulation skin of twisted pair wires should contain information such as the place of origin, implementation standard, product category, and cable length. Cat5 is the identification of Category 5, cat5e is the identification of Category 5, and cat6 is the identification of category 6 ".Products with uppercase lett

Oracle|word Database-built users cannot authenticate to the database until the database is started. The password file holds the username and password of the Sysdba/sysoper user, allows the user to authenticate by password file, log in before the database is started, and start the database. If there is no password file, it can only be authenticated by the operating system before the database is started. The use of Rman, many times the need to nomount,mount in the state of the database processi

At present, desktop computer dual hard disk is not a rare thing, but many friends of the two hard drive set method is not very understanding, and in the case of error settings, it is also very easy to have problems, here we found a dual hard disk set graphics and text detailed tutorials, hope to help the needs of friends. I. Precautions before installation 　　install dual hard drive before the first to check the basic situation inside the computer, such as whether there is a second hard disk sp

the entire company will not be able to access the network and obtain important information during this period. In order to reduce the company's network management costs, avoid network failure to the company caused by economic losses, to ensure that the voice and data communications can be normal operation, improve the enterprise's IT investment rate of return, thereby improving efficiency, system integration, monitoring system, Intelligent building now many large enterprises are starting to se

principle of designing an electronic distribution frame, that is, to help network administrators manage the wiring system. When talking about management, the first step is to have a link database. No matter whether the database is written on paper or stored on a computer disk, it is impossible for network administrators without this database to talk about wiring management. In the face of the wire distribution frame of the webshell, the network administrator will feel a sigh of relief. However,

/Category 5 lines, regardless of their appearance, in terms of touch, there are obvious differences. Fake goods are usually the result of some manufacturers re-packaging the original four or even three categories of lines, which is less than 5 categories/more than 5 linear capabilities, however, it is difficult for general users to identify which seller sells the true amp cable. Based on the author's purchasing experience, I have accumulated the following experience in purchasing the ampo line:F

The password file of Oracle is located in the $ ORACLE_HOME/DBS directory. The naming rule is orapw Before the database is started, the database's built-in users cannot use the database to authenticate their identities. The password file stores the username and password of sysdba/sysoper users. Users can use the password file for verification and log on to the database before it is started. If there is no password file, you can only pass operating system authentication before the database is st

other domestic cable factories, at present, multiple production lines have been introduced for domestic OEM production for multiple foreign brand products. This is called OEM in the IT industry. I was invited to visit some of these factories and found that many foreign brands of twisted pair wires (including cat5e, cat5e, and cat6) are produced here. The products produced in the same production line have different brands, the price difference is also very large, OEM products are usually two to

like a network switch, it is called a rack server. Therefore, a rack-mounted server can be considered as a product that complies with the 19 inch industrial standards. Its exterior is designed according to the 19 inch standard structure and used in conjunction with the 19 inch standard cabinet, to meet the intensive deployment needs of servers in the data center, it also helps improve the appearance inside and outside the cabinet. The guiding ideology of rack-mounted servers is space saving and

To get a PMAC card, first we have to look at his hardware composition (DSP) and the various interfaces (I/O, serial, etc.) provided, and then start to do the preparation (set the jumper), and finally the installation (Socket PCI and adapter board).Hardware composition and interface PMaC is based on the Motorola DSP servo control card, different types of PMAC can control the maximum number of axis channels, DSP models are not the same. There is a speci

? Yes! This depends on the wire. The wire can be used by familiar computer merchants to ask for a few pieces (Figure 12), place the wire in the wire tie circle, and then tie it into the end of the wire tie, remove the extra wire tie head with scissors. Host jumper Patch Cord, a small blue "small cap" that connects two metal pins. Although the jumper is small, it can be used. 1. Three-pin

After the comprehensive wiring is completed, only by using the jumper to connect each link completely, can the communication between computers be realized. 1. Connection of twisted-pair link Typically, each link includes a permanent horizontal link and two jumper lines. One jumper is used to connect the computer to the information outlet of the workspace, and t

networks, commercial buildings and residential buildings. It is also the embodiment of the company's philosophy of "making good use of its effects and enjoying its capabilities" in the VDI field. The Actassi smart cabling system consists of multiple parts: ID-Tracer smart cabling, F2 "super powerful" cable, ID-3 multi-color jumper, and a variety of terminals that are technically aesthetic. When you choose the Actassi series as the SMART network Integ

First, the introduction Today, most of the voice, data and image transmission in office buildings, buildings, university campuses, government departments and even residential communities in intelligent buildings are based on structured cabling systems on their physical structure. We know that in the Iso/osi protocol, the physical layer is the basis of the network system, all network communications rely on the physical layer of the cable to the voice, data to the destination. With the populariza

Horizontal Subsystem The line of the subsystem of the equipment is extended to the user work area, the data part and the speech part use the ISDN five kinds of twisted pair; the function of the horizontal subsystem is to extend the line of the backbone subsystem to the user workspace subsystem. The data, graphics a

simplifies the connection between switches. Uplink port is a dedicated port used to connect to other vswitches. You can use a straight-through jumper to connect the port to any port other than the Uplink port of another vswitch. The connection method is the same as that between the computer and the switch. Note that some brands of vswitches such as 3Com use a common port and Uplink port, and use an MDI/MDI-X switch) to switch between the two types. C
