1. Introduction To achieve non-blocking communication on the existing 100,000-kilometer high-speed trunk cable network, the operator must first consider how to implement automatic protection of optical transmission physical routes. The optical fiber automatic switch protection system is an automatic monitoring and protection system that integrates monitoring, protection, and management. It is independent of the transmission system and completely built

In the past two years, with the decrease in optical fiber costs and the wide application and upgrade of 1000Base and 10G Ethernet, optical fiber communication has gradually become an important part of LAN cabling and FTTx network construction. Due to the electromagnetic interference immunity of optical fibers, we do not need to consider the location Design of electromagnetic radiation devices such as power

The optical fiber access network is worth learning a lot. Here we mainly introduce the technical features of the optical fiber access network. The optical fiber access network refers to the access network with the optical fiber as the transmission medium in the access network. The Optical

Comparison of several types of Integrated Wiring and optical fiber cables What is indispensable in the process of Integrated Wiring is optical fiber cables. What are the advantages of optical fiber cables? The cable type should be comprehensively considered from the cable usage, required transmission capacity, transmission bandwidth, and price. Cable types inclu

The solution for handling 300 or less Ge Fiber switches in Internet cafes is analyzed. The solution for Internet cafes with 150 computers is different from that for Internet cafes with 200 computers. The solution for medium-scale Internet cafes is provided below. Internet cafe owners can check their seats and find their own methods. About 150 Internet cafes The network center uses the RHS4616GMS fully-managed Gigabit Optical

Fiber routers in Internet cafes have been widely used in various Internet cafes. So I have studied how to select an appropriate fiber routers in Internet cafes. I would like to share with you here, hoping to help you. As an industry that is booming today, the Internet bar industry is moving towards scale, chain-based, and group-based development, and the network bandwidth requirements are getting higher and

The optical fiber access network is worth learning a lot. Here we mainly introduce the current situation and development trend of the access network in China's communication industry, including the TMN status of the access network and the remote network management technology of the optical fiber access network, for your reference only. I. Current Situation and Development Trend of access networks in China's

In the SAN storage architecture, the core devices in the fiber channel switch play an important role in the SAN storage process and affect the network performance. Fiber Channel switches provide Fiber Channel switching for high-bandwidth and Low-latency data communication. Currently, fiber channel switches provide conn

End users, or any user who pays for the network connection failure, will pay attention to a major issue of cable, which is why the cable fails. Any network that uses optical fiber cables, its Optical Fiber Links are crucial to the performance of the entire network. Therefore, it is critical to ensure that the optical cable link is always in the optimal state. To help you understand the causes of Optical

The optical fiber access network has become the mainstream of the access network technology, and its characteristics and value have also been favored by many users. So I have studied some innovative technologies of the optical fiber access network, I would like to share it with you here and hope it will be useful to you. At present, the world's optical fiber copp

Document directory Source code Introduction We know that a thread is the most basic unit for program execution. Any program execution depends on the thread execution. A thread is usually a basic component of the operating system. Generally, a thread is created. For example, on Win32, a thread is created using createthread. The operating system actually creates two objects, one is the user-state thread, the other is the kernel-state thread, and our code runs in the user-state thread. When a th

I. Basic Concepts (1) threads SQL Server uses the operating system thread to execute concurrent tasks. If no fiber is used, SQL Server will start the thread and allocate the thread to the CPU by the OS. thread management is controlled by the OS kernel. When a thread completes the process of exiting the CPU, when other thread scheduling occupies the CPU, a context switch will occur. This switch is between the user mode of the application and the kernel

Band Cable The optical fiber cables are made from multiple single optical fiber cables by coloring, stacking into bands and secondary plastic bands. The optical fiber has two types: encapsulation and edge adhesive. The former can withstand horizontal pressure and the latter has a thinner thickness. Each band can contain 4, 8, 12, or 16 optical fibers. The inband

commonly used tail fiber interface type Pigtail is also called the pigtail fiber, is the optical cable terminal box to the equipment to connect between the fiber. Pigtail is often divided into single-mode or Multimode, single-or dual-fiber, transmission distance, and tail fiber
