manufacturers, currently, ATT, alcatel ibm, NT, and Digital products are widely used. 1. ATT sans IMAX has three categories, five categories, cat5e UTP unshielded twisted pair cable, information socket, adapter, photoelectric distribution frame and other products, can support 10 Mbps, 155 Mbps (STM-1 level) 622 Mbps (STM-4 level) end-to-end application, UTP cable characteristic impedance is 100, using unshielded twisted pair balanced characteristics

Mastering the knowledge of Structured Cabling solutions is essential for relevant personnel. How to Design the optimal solution is a constant development of the cabling industry, I believe that more optimized solutions will also be available. Currently, manufacturers of Structured Cabling solutions have released Cat5E and Cat5E solutions. Although the six types of cable standards have not yet been promulgat

High speed is a relative concept. speed is faster than speed. Therefore, a high-speed LAN can be considered based on the fact that fast Ethernet is 100 M in the LAN. Technologies used in this area are mainly Gigabit Ethernet and ATM, and 10 Gigabit Ethernet is being tested. Due to its low cost, good interconnectivity, and many manufacturers, GE Ethernet has become the mainstream technology of high-speed LAN. Construction of High-speed LAN technology Wiring Technology Most of the network cablin

unshielded cat5e and cat5e twisted pair wires. 2. Advantages of twisted pair wires for Image Transmission Twisted Pair wires are used in many industrial control areas that require large interference and long-distance transmission. Lan is also widely used with twisted pair wires, it has the advantages of strong anti-interference ability, long transmission distance, easy wiring, space saving, and low pric

cores number, line 1 to line 8 are the interchange positions of line 1 and line 3 at both ends, and line 2 and line 6.The specific connection sequence of the crossover line is:End: White orange/white green/blue/white blue/green/White brown/brownOther end: white green/White orange/blue/white blue/orange/White brown/brownNote that the wiring order at both ends is different.If you do not know what a crossover line is, you can go to a computer city to sell network products, you just need to tell th

Cat-5e bandwidth is 100 MHz, cat-5e is 155 MHz, and cat-5e is 250 MHz. The single copper cores in category 5 and Category 5 are 24awg, and category 6 is 23awg. No isolation band exists in category 5 and Category 5 lines, and category 6 lines contain a word or cross isolation band. Cat5 is printed on cat5, cat5e is cat5e or 5E, and cat6 is cat6. Category 5 and Category 5 support MB of applications, Categ

network to have once aroused people's concern, along with it, has appeared the equal level near end crosstalk (Elfext) and the echo loss and so on the new key test parameter, therefore, the industry has developed the 5E type Cable technical specification, Its nominal speed is 100Mbps, feel skin thick turn dense, the skin usually note "CAT5e", is generally 305 meters per case; However, with the introduction of the 6-class cable specification, although

This article describes how to delete array elements in javascript and how to clear arrays, for more information about how to delete array elements and clear arrays, see the next article. Simple Method for deleting array elements and clearing arrays using javascript I. Clear the Array Var ary = [1, 2, 4]; ary. splice (0, ary. length); // clear the array console. log (ary); // output [], empty array, which is cleared Ii. Delete array elements Var ar

Push (args) can press multiple elements at a time and return the updated array length.var oldarr=[1,2,3];Alert (Oldarr.push (4,[5,6])) –>5 (this only evaluates [5,6] as an element, returning the updated array length 5)At this time oldarr–>[1,2,3,4,[5,6]]The pop () function only pops the last element at the end and returns the element that pops up and returns undefined if it is called pop () for the number of empty groups.Alert (Oldarr.pop ()) –>[5,6] (this pops up the last element [5,6] instead

VaR arr = ['A', 'B', 'C'];To delete 'B', you can use either of the following methods:1. Delete method: delete arr [1]In this way, the length of the array remains unchanged. In this case, the ARR [1] is changed to undefined, but the index of the original array remains unchanged. In this case, you need to traverse the array element before using it.For (index in ARR)Document. Write ('Arr ['+ index +'] = '+ arr [Index]);This Traversal method skips the undefined element.* Ie4.o is supported later.2.

transmitted bytes. If the call is successful, the number of transmitted bytes is returned. If the call fails, the value is-1, and errno is set.Note: The man Manual states that in_fd must be a file descriptor that supports functions similar to mmap, That is, it must point to a real file.And the out_fd must be a socket. It can be seen that sendfile is designed for transferring files over the network. // Use the sendfile function to transmit the file # include
