For several years, the optical fiber user community has been rapidly shifting from traditional single-mode fibers to new “Full Spectrum” single-mode fibers meeting the International Telecommunications Union (ITU-T) G.652D specification. These Reduced Water Peak (RWP) fibers are considered Full Spectrum because the reduction of loss in the water absorption spectral region (the E band) allows […]

Understanding Polarization Mode Dispersion
Polarization Mode Dispersion (PMD) is a serious problem that can limit distances and data rates in a single-mode optical fiber system. PMD is a time varying quantity that degrades system bandwidth and is costly to mitigate. It affects network reliability and is becoming more evident as network speeds increase. The impact of PMD was first […]
WDM & Next Generation Optical Networking Africa is the newest addition to the highly successful WDM World Series.
Showcasing the rapid growth in the optical market in Africa, the conference will bring together insights and experience of operators and vendors assessing the massive technical challenges the industry faces to deliver high speeds, and ensure that networks are fast enough to handle the current and anticipated traffic demands. WDM & Next Generation Optical Networking […]
Understand Fiber Attenuation
Attenuation is the reduction or loss of optical power as light travels through an optical fiber. The longer the fiber is and the farther the light has to travel, the more the optical signal is attenuated. Consequently, attenuation is measured and reported in decibels per kilometer (dB/km), also known as the attenuation coefficient or attenuation rate. Attenuation varies depending […]
