Passive Optical Components: Optical Circulator

In order to meet the growing demand of communication efficiency, we always apply optical circulator in a fiber optic system because the optical circulator minimizes the loss of light. An optical circulator is a device used in optical communications systems, which can be used to separate optical signals that travel in opposite directions in an […]

Passive and Active Network Fundamentals

Today we have access to more information than ever before. We live in a digital world and bandwidth is what makes a digital world happen. Aging copper networks are being taxed by residential and business customers. However, Passive Optical Network (PON) such as Fiber-To-The-Home (FTTH) are increasingly being deployed to meet the current and future […]

The Basic Parameters of Passive Optical Network Devices

There are many devices elementary but necessary for the Passive Optical Network (PON) applications that require the transmission, combining, or distribution of optical signals. These passive devices include the Optical Splitter/Coupler, Optical Switch, Optical Attenuator, Optical Isolator, Optical Amplifier, and WDM Filters (CWDM/DWDM Multiplexer) etc. Tips: The passive devices are components that do not require […]
