  DWDM stands for Dense Wavelength Division Multiplexing. It is a type of multiplexing technique used in optical fiber to achieve high data transfer using the same optical fiber. DWDM is a type of Wavelength Division Multiplexing (WDM) but a more compact version in-order to transmit and receive high data in the same WDM technology. In DWDM technology, different sources of data are multiplexed so that all the data can use the same optical fiber for the data transmission. In this technology, more than 80 different wavelength of light can be passed through a single pair of fiber. As each light wavelength refers to different data. In this technology, generally all the light wave are multiplexed within 1550 nm wavelength. This is because, in this wavelength the light are tolerable to losses and distortion. But generally, light wave is sent for wavelengths between approximately 1525–1565 nm (C band), or 1570–1610 nm (L band). Multiplexing is achieved in such a way that none of ...

  Have you ever wondered why some networks use a single cable to connect all devices while others rely on multiple connections? Bus topology is a network setup where everything is linked to one central line. But is it the most efficient option for all businesses? What is Bus Topology? Bus topology is a network design where all devices (computers, printers, servers) are connected to a single central cable, the bus or backbone . This cable acts as the primary communication channel, transmitting data between devices. Each device listens for data meant for it while ignoring other transmissions. Terminators at both ends of the cable prevent signal interference. It is a simple and cost-effective network structure, but its main drawback is that the entire network goes down if the central cable fails. Examples of Bus Topology Here are some examples of networks that have used bus topology: Ethernet (10Base-2 and 10Base-5) – Early Ethernet networks used a bus topology with coaxial cables. ...
