is similar to the RJ-11 telephone line in shape and exterior, but wider, due to the difference in size between the two (for 4 or 6-pin, RJ45 for 8-pin connectors ), obviously, the RJ45 plug cannot be inserted into the jack. In turn, it is physically feasible (the plug is smaller than the RJ45 jack), which makes people mistakenly think that the two should or can
Nowadays, optical transceiver network devices are increasingly used in our network engineering. They are used in small-scale optical fiber trunk connection solutions, so it is better to use optical fiber interfaces for switches in large-scale optical fiber trunk. Because of the various types of optical fiber, wavelength, interface type, rate, and other technical indicators, a wide range of Optical Fiber transceive
Application of RJ45 short circuit ring on gigabit Nic1. Topic OriginFor those who often work on multiple operating systems, using Windows as the host system with Vmware Workstation is already a standard Workstation. I personally traveled back and forth between Windows and Linux and used the notebook configuration as Windows 7 as the host, VMWare Workstation 9 to install the Virtual Machine CentOS and OpenBSD. Virtual Machine network connection is set
One end of the optical transceiver is connected to the optical transmission system, and the other end is the 10/100 M Ethernet interface. Optical fiber transceiver achieves photoelectric signal conversion. The main principle of the optical transceiver is achieved through photoelectrical coupling.
Optical Transceiver ge
The RJ45 interface is typically used for data transmission, and the most common application is the NIC interface.
RJ45 is a type of different joints; RJ45 head According to the order of the line there are two different ways, one is orange white, orange, green, blue, blue, white, green, brown, Brown, the other is green, white, green, orange, blue, blue, white, or
Indication of the indicator meaning:Power (green): "Solid" indicates that the fiber transceiver is in power state;LFP indicator: "Solid" indicates that the LFP function is turned on, "normally extinguished" means that the LFP function is closed;Fx_link/act (green): "Solid" indicates that the fibre port connection is valid, "flashing" indicates that the transceiver is receiving or transmitting data from the
We know that the cable is the basis of the network, if you do not well identify the use of the cable, you will not become a qualified engineer.The BNC cable is the copper shaft cable that we use for CCTV, which is used today as a signal input/output probe in an oscilloscope, although the appearance and the traditional cable are somewhat different, but the function is similar. It is mainly used in the network between the operator optical end machine to the router this link, is commonly known as t
Let's talk about the playing style and Tactics of RJ45 line sequence.
The wiring standards of EIA/TIA define the line sequence 568a and 568b of the two twisted pair wires.568a standard:Green white -- 1, green -- 2, orange white -- 3, blue -- 4, blue white -- 5, orange -- 6, brown white -- 7, brown -- 8568b standard:Orange white -- 1, orange -- 2, green white -- 3, blue -- 4, blue white -- 5, green -- 6, brown white -- 7, brown -- 8
Used for Ethernet (Ethernet 10/100/1000 m UTP/STP Interface), commonly used in Category 5 unshielded twisted pair wires. RJ-45 is also used for other interfaces such as ISDN, pins are defined differently.
Listen 48 connector:
Used to connect T1, E1 serial lines, usually using shielded twisted pair wire; RJ-48 can also support pin3, pin6 Grounding Conn
RJ45 the definition and standards of the relevant provisions.
RJ45 is a commonly used name, referring to the standardization of IEC (60) 603-7, using a modular jack or plug of 8 locations (8 pins) defined by the International connectors Standard. IEC (60) 603-7 is also the ISO/IEC 11801 International General cabling Standard Connection hardware reference standard.

Many people (including the author) think that 10 Base-T 10 m networks use four of the eight signal lines in the network cable, the 100 Base-t m uses all eight signal lines (or how fast ?). However, when the author recently used a 10 m direct connection method (switching between 1 and 3, 2 and 6, and shielding the other four lines) to connect the network cable, unexpectedly, it was found that the Network was being transmitte
is different access to the optical line, is the light signal. Optical signal conversion and interface protocol after the conversion of the router, he belongs to a wide area network access, that is, often said fiber access, as long as the presence of optical fiber in the place need to convert the light of the cat.
Optical fiber transceiver is the conversion of photoelectric signal in LAN, but only signal conversion, there is no interface protocol con
In the domestic common information development and implementation projects, most of the work of the development of the workload is concentrated in order to adapt to different customer needs, the specific modules to modify, and ultimately achieve customer expectations of the software functional characteristics. But for the development of vendors, in the face of different customers to develop different software versions, will lead to duplication of labor, cost rise, maintenance incre

When using a fiber-optic transceiver, it is necessary to pay attention to some problems in order to make the use of fiber-optic transceiver better.
1. View whether full duplex or half-duplex is supported.
Some of the market can only use a full dual public environment, can not support Half-duplex, such as receiving other brands of switches or hubs, and it uses Half-duplex mode, otherwise it will cau
