In order to support different span lengths between Optical Amplifiers in a transmission link, as well as to provide for aging of the link, it is desirable for an optical amplifier to support as large as possible dynamic gain range, i.e. to allow the gain to be dynamically configured over a wide range. For a […]

Advanced Optical Components – Optical Attenuator
What is Optical Attenuator? Optical Attenuator (or fiber optic attenuator) is a passive device that is used to reduce the power level of an optical signal. The attenuator circuit allows a known source of power to be reduced by a predetermined factor, which is usually expressed as decibels (dB). Optical attenuators are generally used in […]
Some Optical Factors about Affecting the Modulator
Multi-channel communication of different systems need to consider the combined information from different channels, the transmission of signal through a fiber optic link and the separation of a single channel receiver prior to routing to their destination. So the application of IO in this field is to provide optical multiplexer, the method of modulation and […]
Optical Attenuator Types and Applications
Optical attenuator is a very important fiber optic passive components. It’s an indispensable device for fiber CATV. So far the market has formed four series that are fixed-step, variable, continuously variable and intelligent optical attenuator. Types of Optical Attenuators A. Displacement Optical Attenuator As we all know, when the two sections of optical fiber connection, […]
What you need to know before you purchase Fiber Optic Attenuators
So why do We Need a Fiber Optic Attenuator? 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 […]
Several Variable Optical Attenuator Introduction
Variable optical attenuator (VOA) has a wide range of applications in optical communication, and its main function is to reduce or control the optical signal. The basic characteristics of fiber optic network should be Variable, especially with the application of DWDM transmission systems and EDFA in optical communication, it must be carried out in a […]
