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.

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
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
Abstract:Cp2101 and its upgraded product cp2102 are highly integrated USB-UART bridging circuits manufactured by the United States's silicon company. They can use the simplest external circuit, the least external device and the smallest area of the circuit board for easy conversion from USB2.0 to UART. This paper introduces the main features and practical application methods of the circuit.

The test of the optical cable cabling system is a necessary step for project acceptance. It is also the final process for the project contractor to honor the contract with the real estate owner. Only after the system test is passed can the cabling system be completed.
The connectivity of devices is the most basic requirement for wiring system testing. The effectiveness of jumper systems can be easily tested. It is relatively difficult to test the indicator data of communication lines, generally,
Before establishing a dormitory network, you need to know the networking types. Generally, the LAN topology can be divided into BUS-type BUS, star, ring, and other types.

The network adapter is connected to the network. Therefore, an interface must be provided to connect the network adapter to other computer network devices. Different network interfaces are applicable to different network types, at present, common interfaces include Ethernet RJ-45 interface, fine coaxial cable BNC interface, coarse coaxial electrical AuI interface, FDDI interface, ATM interface, etc. In addition, some NICs provide two or more types of
