10gb transceiver

Debug fiber Interface interface with FPGA:Due to the needs of the project, the previous period of time debugging the optical fiber interface, recording some design experience.In the design, FPGA is used to control optical fiber module to complete the transmission of optical fiber data, FPGA uses Xilinx company's Spartan6 lx45t, because of its internal 2 GTP transceiver, can be used as a variety of communication protocol (Gigabit Ethernet, Pci-e,sata,

protocol stack send function, to achieve data wireless transmission③ Receive: Receive node calls the protocol stack wireless receive function, realizes the wireless data receivesSince the protocol stack encapsulates these functions, it is convenient for us to use them. Here is the protocol stack wireless send function:A better application of the protocol stack requires a detailed understanding of the specific role and significance of these functions and their parameters provided by the protocol

are no special application requirements, it is advisable to select the device in these two companies.Hardware Resources for 5.1.2 devicesHardware resources are important criteria for device selection. Hardware resources include logical resources, I/O resources, cabling resources, DSP resources, memory resources, phase-locked loop resources, serial transceiver resources, and hard-core microprocessor resources.The need for logical resources and I/O res

number of tasks of Integrated Wiring. However, twisted pair wires have weak anti-aging capabilities, and only one image can be transmitted at a time. Therefore, it is suitable for video surveillance of network cameras in medium and short distances, with relatively scattered camera points, or with relatively close but concentrated points, such as banks, hotel chains, supermarkets, or university campuses. Optical fiber.Optical Fiber Transmission has the following advantages: long transmission dis

parabolic surface, so that the antenna is located in the parabolic surface of the internal reflection focus, through the electromagnetic waves reflected in the focus of the formation of energy concentration, thereby enhancing the electromagnetic signal transceiver, To achieve enhanced signal in a specific direction. The key to making a simple gain antenna is to find a more regular metal parabolic surface and compute the focus position of the parabo

direction, and if any network segment are severed, all network transmission ceases. A host on a bus network is called a station or workstation. In a bus network, every station receives all network traffic (traffic), and the traffic generated by each station have equal Tran Smission priority. Each network segment is, therefore, a collision domain. In order for nodes to transmit on the same cable simultaneously (simultaneous), they use a media access control technology such as car

multicast distribution service, is a broadband point-to-point access system that can access voice, data and video services. LMDS system using millimeter wave transmission, working in the 20-40ghz band, can provide up to 155.52Mbps user access rate, known as a "Wireless optical fiber" access system. In addition, the LMDS system supports all major voice and data transmission standards, such as ATM, TCP/IP, and MPEG-2.The *LMDS system adopts a kind of honeycomb structure configuration, by which on

Jérôme Petazzoni (Docker evangelist) Translator: Mark Shao (senior engineer, EMC China) If you use Docker on CentOS, Rehl, Fedor, or other Linux distributions that do not have AUFS support by default, you may need to use Device Mapper's storage plug-in. By setting this plugin as the default, it will store all your containers in a short 100G file and limit the maximum of 10GB per container. This article will show you how to break this limit and m

ProcessThe GC optimization process is similar to the process of most performance improvements. Here is the GC optimization process I used.1. monitor GC statusFirst you need to monitor the GC to check the various states of the GC during system execution. Please refer to the monitoring method mentioned in the previous article to become a JAVAGC expert part ii-How to monitor the Java garbage collection mechanism.2. After analyzing the monitoring results, decide whether to perform GC optimizationAs

In fact, in the architecture is to refer to the following 10GB/S media Independent interface (Gigabit media independent interface,xgmii), can also be seen as an extension of the XGMII interface. The xgmii is an interface with 74 signal lines, of which 32 data lines are used for sending and receiving data. The xgmii can also be used as the MAC layer of Ethernet to complement PHY. Xaui can also be used to replace the Ethernet MAC laye

Vro interfaces are very important for network connection and routing functions. Here we will give a comprehensive explanation of vro interfaces and connection knowledge. A vro has powerful network connection and routing functions. It can be physically connected to a variety of different networks, which makes the router interface technology very complex, the more high-end router interfaces there are, the more network types it can connect. Vro ports include LAN ports, WAN ports, and configuration
