by the manufacturer, or directly use RJ45 connector. The method is as follows: RJ45 glass can be directly accessed from the front, the value ranges from left to right from 1 to 8, which corresponds to the 1-8th end of the DB9 connector. This project uses the latter, the advantage is to reduce the number of connections and improve the stability of communication.2. cat5e shielded twisted pair wires are used in communication media, mainly considering th
control first. Compared with HDMI, its transmission line is cat5e/6 type, which is cheap and has a maximum transmission distance of 100 meters. More universal is that its interface is universal RJ-45 head (twisted pair head), capable of delivering HD videos, 3D, and up to 2 k x 4 K (4096x2160).

network cable and connection hardware, it is easier to keep the characteristic impedance of the whole channel consistent, so as to get the ideal RL value. 2, on-site production jumper The site is used to make jumper cables, which are generally the remaining fraction lines of the horizontal wiring. Horizontal cable conductor structure is a solid conductor, cat5e using AWG24 (1/0.511mm), Cat6 using AWG23 (1/0.574mm) bare soft copper single line. The
Find the right cabling scheme Currently, structured cabling solutions vendors are offering enhanced 5-class (CAT5e) and 6-Class cable solutions. Although the 6-class cable standards have not yet been promulgated, many customers have chosen to implement this solution given their superior performance. What prompted them to install such systems in the 6 class of standards that have not yet been finalized? The continuous refinement of the 5E class of

For example, according to the author's network wiring experience, system cabling of the entire floor or building can reduce network communication maintenance personnel to half of the original. Because the systematic and structured netwo

Cascade GBIC Module
The GBIC modules used for Cascade are divided into four types: one is 1000Base-TGBIC module, which is applicable to cat5e or cat6 twisted pair wires with a maximum transmission distance of 100 meters; the other is 1000Base-SXGBIC module, suitable for Multimode multi-fiber (MMF), with a maximum transmission distance of 500 meters.

The cabling in the building uses cat5e cabling products, and four pairs of UTP cables are laid to each work position centered on the wiring room.Network DeviceIn view of
When the number of ports that a single switch can provide is insufficient to meet the requirements of the network computer, more than two switches must provide the corresponding number of ports, which also involves the connection between switches. Basically, there are two ways to connect vswitches: Stack and cascade.

Minimum bending radius
For the minimum bending radius, see the cable diameter. It is usually expressed in multiples of D (Cable diameter. The diameter of cat6 cables is generally greater than that of cat5 cables. Therefore, the actual radius of cat6 cables is generally greater than that used in cat5 cables.

For T568B and later standards, the Basic Link has been eliminated, the replacement of its Permanent Link is also controlled at a maximum length of 90 meters. Various parameters of the Link beyond this length are prone to negative values during testing, if Channel is used for testing, the result may still be in the normal range. On the other ha

The dual-nic is connected to the Internet, of course, the network cable is indispensable, just as I used to work in a wiring company, so I asked my former colleagues for a twenty pair. Here, the commonly used network cables are cat5e unshielded twisted pair wires. Careful users will find that there are eight different color pairs of wire cores in the twisted pair wires, each of which is twisted together, this
