Types and Basic Principles of Broadband Fiber Sources

Posted on May 20, 2014 by Admin

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 →

WDM Filter Technology

Posted on May 7, 2014 by Admin

WDM filters provide access to all wavelength channels, where required. In Optical Termination Multiplexers (OTMs), all channels are terminated. Between two OTMs, use of a subset of channels are usually necesary. This leads to the concept of Optical Add/Drop Multiplexer … Continue reading →

Wavelength Division Multiplexing Technical Overview

Posted on April 28, 2014 by Admin

The Wavelength Division Multiplexing (WDM) system uses a Multiplexer (MUX) at the transmitter to put multiple optical signals on the fiber along with a DeMultiplexer (DeMUX) at the receiver to split them from the fiber. The signals use different wavelengths. … Continue reading →
