x2 transceiver

There are many different classifications of fiber optic transceivers, and most of the attention is being paid to categories that are differentiated by fiber connectors: SC connectors, fiber transceivers, and fc/st connectors. When using a fiber-optic transceiver to connect to different devices, you must be careful to use different ports. 1, optical transceiver to the 100BASE-TX device (switch, hub) conn

situation of Internet cafes users, the main link is worth the Internet Café users reference, we recommend the first way. The first is the use of optical fiber transceiver to achieve the connection between the fiber and the dual-Wan port router, this way the biggest feature is the low input cost, but also the most suitable for Internet users a way. In the choice of fiber transceiver, the performance is of

Twisted Pair wires have two connection standards: EIA/TIA 568B standard and EIA/TIA 568A standard.

Crossover line: One end is connected in T568A line Order and the other end is connected in T568B line order. Connection Met

no longer possible to inherit from another base class. Therefore, it is a good idea to provide an abstract interface (interface), a class can implement multiple interfaces, thus simulating the implementation of "multi-Inheritance", for the design of the class provides greater flexibility. Minimizing the direct access to variables the encapsulation principle of data should be normalized, not exposing the properties of one class to other classes, but should protect them by means of access, which

Edge X0-y1 and Edge x1-y1.2, for Xi belongs to the nots,yi belongs to the Nott side, their respective top mark has not changed,Lx[i] + ly[j] did not change, that is, these edges are not in the eq

It was a long-time problem.Test instructions: From the upper left-hand corner of the grid select a path to the upper right corner and then back to the upper left corner, and two paths in addition to the start and end point cannot have coincident points. Ask what's the biggest and what's in the grid.State Design : We can think of two paths starting from the top left and then reaching the lower right corner at the same time. It is easy to see that all possible squares of the first k stages constit

theory is not only used to solve the problem of the one-dimensional high-order equation. The group theory originally used to solve higher-order equations can basically be considered as a replacement idea. The solution group (solution space or solution set) of the equations that can be solved by algebra is a replacement group. Each high-order equation corresponds to a solution set or a solution group. The problem of solving this high-order equation is transformed into studying the nature of the

In the composition of wireless networks, the use of many devices deserves a detailed understanding. Today we will talk about the failure of VLAN wireless Internet access switches. The following is an experience shared by a netizen: A strange problem occurs in the VLAN of the two departments where an office area is located. Some websites on the Internet can be accessed normally, but some websites cannot; emails received through Outlook or Foxmail are normal, and small emails without attachments a
