Capacity Expansion and Flexibility—DWDM Network

DWDM increases the bandwidth of an optical fiber by multiplexing several wavelengths onto it. Even though it costs more than CWDM, it is currently the most popular WDM technology because it offers the most capacity. This article provides an overview of DWDM networks and … Continue reading

Types and Basic Principles of Broadband Fiber Sources

Four general types of broadband fiber sources have been investigated: namely, resonant fiber lasers, superfluorescent fiber sources, wavelength-swept fiber lasers, and sources involving an SLD and an Er-doped fiber amplifier (EDFA). Their principles are briefly reviewed in this article. (Related … Continue reading
