Since the early years of fiber optics, there has been a need to passively switch, tap, split, and multiplex optical signals. Today’s technology allows designers to expand on these original tasks by also providing the ability to direct, control, and filter optical signals for more creative and cost-effective system designs using innovative passive devices. This […]

Things You Should Know about Optical Attenuator
We always utilize an amplifier to improve signal electricity in fiber optic transmission. But what if there is too much light deliver through a fiber optic receiver? At that time, you may need an optical attenuator to reduce the power level. This post will help you get better understanding of optical attenuator. An optical attenuator, or […]
How to Test the Sensitivity of a Fiber Optic Receiver by using an Optical Attenuator
Knowing how to test the sensitivity of a fiber optic receiver is an important skill. A fiber optic receiver provides optimal performance when the optical input power is within a certain range. But how do you test the receiver to see if it will provide optimal performance at the lowest optical input powers? One way […]
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 Exactly Are Fiber Optic Attenuators
A fiber optic attenuator, also called an optical attenuator, simulates losing the could be caused by a long period of fiber. Typically, this device performs receiver testing. While an optical attenuator can simulate the optical loss of an extended period of fiber, it can’t accurately simulate the dispersion that would be caused by a long […]
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 […]
