FC Fiber Optic Attenuator

FC Fiber Optic Attenuators are very popular in telecommunication networks.They are used to reduce optical light intensity for optimal operating condition or to equalize optical power across light wavelengths in a Wavelength Division Multiplexing fiber system.

FC optical attenuator a variety of applications.

Male to Female Doped Fiber Plug Type FC Fixed Attenuator

This type of attenuators are also called build out types. They contain doped fiber suitable for both 1310nm and 1550nm operation. Fixed attenuation values are available in 1dB increments from 1 to 20dB.

The build out FC attenuators are installed between an mating sleeve and a connector. Because they are based on doped fiber, this type of attenuators have exceptional optical performance and reliability.

Female to Female Absorption Filter Adapter Type FC Fixed Attenuator

This type of attenuators are also called bulkhead type. They incorporate absorption filters in the centers of the adapter housings. In use, the filters are interposed between the end-faces of mating plugs.

Bulkhead attenuators utilize a wavelength sensitive neutral density filter to achieve attenuation. They can be inserted easily between jumpers or permanently mounted in a fiber distribution cabinet. This type of FC attenuators can be used for either multimode or single mode applications.

They use a filter to induce attenuation and are wavelength dependent, so you need to choose between 1310nm or 1550nm versions.

Applications

FC attenuators are widely used in telecom and data networks, power equalization in DWDM networks, CATV and multimedia applications, testing instruments, Fiber to the Home, and more.
