DWDM is an innovation that enables multiple optical carriers to travel in parallel in a fiber. DWDM devices combine the output from several optical transmitters for transmission across a single fiber. At the receiving end, another DWDM device separates the combined optical signals and passes each channel to an optical receiver. Only one optical fiber […]
DWDM EDFA
Basic Knowledge About EDFA
In optical communication network, signals travel through fibers for very large distances without significant attenuation. However, when the signals need to transmit several hundreds of kilometers, it becomes necessary to amplify the signals during transit. EDFA (erbium doped fiber amplifier), commercialized in the early 1990’s, became a key enabling technology for optical communication networks, and […]
Fiberstore Updates Two New Types in DWDM System Amplifiers Category
Dec. 25th, Shenzhen, Fiberstore News – This week, Fiberstore is going to introduce a new update of product types in DWDM system amplifiers category. These two new types including Raman Fiber Amplifiers (RFA) and Inter-stage DCM supported EDFA Amplifiers will be good choice for your amplifier requirements. Erbium-Doped Fiber Amplifier (EDFA) and Raman Amplifier are the most common type […]
A Comparison between CWDM and DWDM
Transporting a single data stream through an optical fiber can be costly and inefficient. Wavelength Division Multiplexing (WDM) technology can transmit multiple, independent data streams through a single optical fiber to better utilize the bandwidth of the given optical fiber. Each data stream adopts a different wavelength of light (also know as lambda λ) and […]
