Common Solutions for A Secured DWDM Network

Common Solutions for A Secured DWDM Network DWDM (Dense Wavelength Division Multiplexing) is an optical technology used in fiber optics to increase bandwidth over existing fiber optic backbones. Due to the large capacity, high survivability and flexibility, DWDM technology is common to be seen in backbone network and long haul transmission. However, in the actual cases, problems like optical fiber faults and line interruption may affect the communication and services tha

Passive DWDM vs. Active DWDM

DWDW is short for dense wavelength division multiplexing. It is an optical multiplexing technology used to increase bandwidth over existing fiber networks. DWDM works by combining and transmitting multiple signals simultaneously at different wavelengths on the same fiber. It has revolutionized the transmission of information over long distances. DWDM can be divided into passive DWDM and active DWDM. This article will detail these two DWDM systems. Passive DWDM Passive DWDM systems have no ac

Single Fiber CWDM MUX and DEMUX Tutorial

In CWDM networks, bidirectional CWDM MUX DEMUX (also called dual fiber CWDM MUX DEMUX) uses the same wavelengths for transmitting and receiving. It is often used in dual way transmission applications. The working principle is easy to understand. A duplex fiber cable links two dual-fiber CWDM MUX DEMUXs supporting the same wavelengths installed on each end of the fiber optic network. The wavelengths of the two fibers are the same, but they are running on the different directions for duplex transm

Complete Analysis on DWDM Technology

Complete Analysis on DWDM Technology It has been over 20 years since DWDM technology first came on the scene, and in the last two decades it has revolutionized the transmission of information over long distances. At present, DWDM technology is so widely applied that we almost forget that there was a time when it did not exist and when accessing information from the other side of the globe was expensive and slow.
