fiber steel tube FWDM module

Share

The steel tube filter wavelength division multiplexer series are based on environmentally stable thin film filters technology. 

The devices combine or separate light at different wavelengths in a wide wavelength range. These components have been extensively used in EDFAs, Raman amplifiers, fiber sensor systems, WDM networks and fiber optics instrumentation.


Product description

Description

An FWDM (Fiber Wavelength Division Multiplexer) module is a type of device that is used to combine multiple wavelengths of light onto a single fiber optic cable. This allows multiple channels of data to be transmitted over a single fiber optic link, increasing the capacity of the network. FWDM modules are typically used in high-bandwidth applications such as data centers, where a large amount of data needs to be transmitted over long distances. They are often used in conjunction with other types of optical networking equipment, such as amplifiers and repeaters, to extend the reach of the network. FWDM modules are available in a variety of different form factors, including pluggable modules and rack-mountable units. They may be made of various materials, including fiber steel tubes, depending on the specific application and design requirements.
