Optical attenuator is a passive device used to reduce the power level of an optical signal. It is generally used in single-mode long-haul applications to prevent optical overload at the receiver. Optical attenuator is widely used in CWDM&DWDM, CATV systems, data center networks, test equipment and other high power applications.


Fixed attenuator, as the name of which has indicated clearly, is designed to have an unchanging level of attenuation, expressed in dB, such as 1dB, 5dB, 10dB, etc. Fixed value attenuators consist of in-line type and connector type. In-line type looks like a plain fiber patch cable. It has a fiber cable terminated with two connectors which you can specify types. Connector type attenuator looks like a bulk head fiber connector, with a male connector interface on one end and a female interface connector on the opposite end. It mates to regular connectors of the same type such as FC, ST, SC and LC. Their applications include telecommunication networks, optical fiber test facility, Local Area Network (LAN) and CATV systems.

• Useful for testing the dynamic range

• Reduce the optical power within a fiber optic link

• Useful in very short fiber links

• Low Back Reflection

• Available in Singlemode & Multimode

Fiber optic attenuator is a passive device used to reduce the power level of an optical signal because too much light can overload a fiber optic receiver and degrade the bit error ratio (BER). To achieve the best BER, the light power must be reduced by using fiber optic attenuator. Generally, the optical attenuators are used in single-mode long-haul applications to prevent optical overload at the receiver.

Optical attenuator reduces signal power by absorbing the light, like sunglasses absorb the extra light energy. Or by scattering the light like an air gap. Fiber optic attenuators are commonly used in two scenarios:

  • Attenuators are permanently installed in a fiber optic links to properly match signal levels at transmitter and receiver.

  • In fiber optic power level testing. Attenuators are used to temporarily add a calibrated amount of signal loss in order to test the power level margins in a fiber optic system.

Fiber optic attenuator is an essential passive component in the optical communication system. With the advancement of DWDM technology, as well as the potential to flexibly upgrade the reconfigurable optical add-drop multiplexer (ROADM), the demand for optical attenuator is sure to soar, especially for optical variable attenuator. The innovation in fiber optic industry never ceases, and fiber optic attenuator will evolve to have lower cost, faster response time and enhanced integration of hybrid with other optical communication devices.
