interoperability. In short, where fiber resources are scarce, where can be used WDM transmission system, not only to solve the problem of resource shortages, but also can greatly solve the rental of optical fiber or laying optical cable more cost savings. Next, I will give you a few very typical WDM transmission system application scenarios. 650) this.width=650; "src=" Http://s3.51cto.com/wyfs02/M01/6E/FE/wKiom1WOTjSBaqjwAAEu6ILl5JI543.jpg "title=" Point-to-point wavelength division multiplexin

than the protection channel provided by the SDH system for traffic signals such as GBE, which transmit large particles. From the above two aspects is not difficult to see, when the network of operators in the optical fiber resources are relatively tight, and the network has a large number of data service transmission requirements, the use of Metro DWDM system to build core optical network is a very ideal solution. It is noteworthy that in the transport interface layer, the transport access la

network extension applications have different transmission bandwidth requirements and quality of service requirements between storage networks. The following illustration shows their relationship. These transport bandwidth and quality of service requirements determine the required storage network expansion technology. The choice of storage network extension technology At present, storage network expansion technology can be broadly divided into four categories: 1 traditional channel Exten

the recovery function of SDH network. Mippo Ethernet: Enables Ethernet networks to be transmitted through multiple wavelengths or multiple light waves or a single optical fiber, thereby greatly increasing network capacity. CWDM: Compared with DWDM, CWDM is more suitable for building a metropolitan network, it transmits a small number of wavelengths in one fiber, while

participated in the database implementation and operation of Vplex bi-active and ASM double-live, and has a practical experience to talk about the two current dual-activity programs.First, we talk about the main differences between extended RAC and common RAC. Mainly distance, distance is to prevent such as natural disasters, terrorist attacks and other data center damage, another database center can still provide services. However, the distance will bring additional network and IO delay, so th

cable access distance, improve access to bandwidth, to achieve universal user width with business access. For a small number of large customers high bandwidth access requirements (such as 10M, 20M or more bandwidth), the use of optical cable access transmission. Therefore, in the implementation of "light into the copper back", combined with integrated access to the network planning to make access to the layer of optical cable planning and construction, the optical junction point and access to t

compatibility problems with old devices. The speed is of course the fastest to support n, but it should also be determined by specific devices. Which of the following is the best choice for bandwidth options: 20, 40, and automatic? In general, 20Hz bandwidth is not very high, there is no difference with 11g... 40Hz is because the channel resources are insufficient after the 11N wireless bandwidth is increased, and the bandwidth needs to be expanded to increase the network speed... If 20Hz is

Effective Area and low dispersion maintenance, and its PMD value is extremely low, so that the capacity of the existing transmission system can be easily upgraded to 10 ~ 40 Gbit/s, and easy to use Distributed Raman effect amplification on optical fiber, greatly extending the optical signal transmission distance. 2) New Low-peak optical fiber for man Communication In the metropolitan area network design, you must consider simplifying devices and reducing costs, and consider the possibility of n

Java NiO provides a different way of doing IO than standard IO: Channels and buffers (channels and buffers): Standard IO operates on byte streams and character streams, whereas NiO operates on channels (Channel) and buffers (buffer), which are always read from the channel to the buffer or written from the buffer to the channel.Asynchronous IO (Asynchronous IO):

Channels can be compared to RJ45 network cables, a total of 11 available channels. Considering that there are overlapping regions between the adjacent two wireless APs, in order to ensure that the signal channel used in this part of the region can not be covered by each other, the wireless AP with the specific signal covering each other must use different channels
