40g transceiver

1. What is gttransceiver? The gttransceiver is a type of FPGA line speed up to 500 Mb/s. the 6 Gbit/s Transceiver can be flexibly configured using FPGA's internal programmable resources, making it suitable for different needs such as Ethernet and sata1.0 interfaces, it serves the physical layer of various high-speed serial interfaces. For the spartan6 series, the gtpa1_dual contains two GTS transceiver, or

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,

extraction processes does not meet the performance requirements, it is split according to the following guidelines.Principles 2 : ensure data and business consistency, configure processes by business coupling: There are business coupling objects that must be configured in an extraction process;Principles 3 : by Redo Log Volume configuration process: In the hour estimate, at the peak of business, a single extraction process per hour processing redo amount of not more than

be seen (as shown in Figure 2), to 2015 years more than 50% of the network device port with 10G port, and about 25% of the port will be used 40g/100g. From the related forecasts mentioned above, we can see that the network evolution of cloud computing data Center is very clear 唽 direction. In order to reduce the delay of the network and improve the response speed of the data center network, the cloud Computing data Center will adopt the core + Acc

With the rapid development of the Internet in recent years, the number of Internet users, application types, bandwidth needs, and so on have all experienced explosive growth. Taking China as an example, the annual growth rate of the Internet traffic in the next four or five years is expected to reach 60 ~ 70%, the total bandwidth of the backbone transmission network will increase from 64 Tbit/s to about 150 Tbit/s, or even more than 200 Tbit/s. With the implementation of the "Broadband China-opt

supports wire rate forwarding, the bandwidth calculation method of the backplane is very simple: the number of ports * the corresponding port rate * 2 (full duplex mode), of course, the backplane can also be designed into a redundant mode, some backboard bandwidth can be provided, so that the forwarding between slots has multiple backboard channels. If some of the backboard channels are faulty, the service will automatically switch to achieve redundant backup. Now, the bandwidth of the high-end

growth of the data volume, so the data volume of the Enterprise Data center will continue to increase, in its current in the million backbone, Gigabit access based on the network, we should also consider how integrated cabling to meet the needs of the next few years of network transmission, data center in the next few years will gradually realize the gigabit access, 40g/100g backbone of the network transmission mode.Tobacco Enterprise Data Center in
