What you need to know before you purchase Fiber Optic Attenuators
No Commentsby www.fiber-mart.com Bigger is much better, right? Or so many people believe. Beginners in fiber optic technology are often confused with why optic attenuators should reduce light intensity. Aren’t we using amplifiers to improve the signal electricity? The fact is that too much light can overload a fiber optic receiver. [ Continue reading…]

How DWDM System Components Work Together with DWDM Technology
No Commentsby www.fiber-mart.com As DWDM system is composed of these five components, how do they work together? The following steps give out the answer (also you can see the whole structure of a fundamental DWDM system in the figure below): 1. The transponder accepts input in the form of a [ Continue reading…]
DWDM System Components
No Commentsby www.fiber-mart.com A DWDM system generally consists of five components: Optical Transmitters/Receivers, DWDM Mux/DeMux Filters, Optical Add/Drop Multiplexers (OADMs), Optical Amplifiers, Transponders (Wavelength Converters). Optical Transmitters/Receivers Transmitters are described as DWDM components since they provide the source signals which are then multiplexed. The characteristics of optical transmitters used in DWDM systems [ Continue reading…]
Introduction to DWDM Technology
No Commentsby www.fiber-mart.com DWDM technology is an extension of optical networking. DWDM devices (multiplexer, or Mux for short) combine the output from several optical transmitters for transmission across a single optical fiber. At the receiving end, another DWDM device (demultiplexer, or DeMux for short) separates the combined optical signals and passes each channel [ Continue reading…]
