point-to-point Wavelength division multiplexing (WDM) system to increase the bandwidth, this optical network is widely used in long-distance backbone network transmission, can provide dozens of wavelength OC-48 (2.5gbit/s) or OC-192 (10GBIT/S) signal channel. The optical network uses static channel allocation technology to provide a fixed transmission channel between two points. The next Generation Optical network is an intelligent Optical network (

. Metal wires can also be used for transmission, but the wire has higher signal loss, electromagnetic interference, and higher maintenance costs. The packet may pass through both media during transmission, but for any long distance transmission, the fiber is unavoidable.Optical fiber has obvious bandwidth advantages, because each fiber can carry many different wavelengths of light (channel), which is wavelength division multiplexing (WDM) technology.

Understanding of USB driver

Understanding of USB driver I have learned about USB drivers for more than two weeks. The following is a summary !!!!!!!!1. Each device corresponds to a PDO, and each PDO corresponds to multiple FDO. In the driver, the corresponding PDO and FDO are not the hardware. For USER-to-KERNEL communication, the system packs each USER request into an IRP structure, sends it to the driver, and identifies the PDO in the IRP to identify the device to which the request is sent. In addition, in terms of drive

Concept and importance of optical signal-to-noise ratio (osnr)

Spectral Analysis of Optical Signal-to-Noise Ratio of optical fiber networks The spectral analyzer (OSA) was originally used to measure the power spectrum of optical signals. After the introduction of wavelength division multiplexing (WDM), spectral analyzers were popularized because the standard power meter could not distinguish multiple wavelengths (optical power under the channel ). However, although most people are familiar with the typical applic

Streaming Media Processing has always been widely concerned by the industry for its complexity and technology. With the popularity of the Internet, streaming media has been widely used on the network. How to Make Streaming Media Processing simple and effective has gradually become the focus. Choosing an appropriate application solution will get twice the result with half the effort. At this time, Microsoft DirectShow gave us a good choice.

station NodeB and the base station controller RNC. Because node B is usually very decentralized, the transmission from Node B to RNC often requires access and aggregation of two tiers of network, while the implementation of Node B traffic statistics multiplexing and convergence to improve transmission bandwidth utilization and reduce the ability to support the RNC port too high requirements, In Utran transmission network, 3G service is often required to converge on ATM/IP.
