Attenuators

Attenuators

eFiberTools offers a range of fiber optic Attenuators for Singlemode 9/125, Multimode 50/125 and Multimode 62.5/125 applications. LC attenuators, ST, SC, LC/APC, SC/APC, FC and FC/APC types.

The adjustable attenuator uses an air gap for the attenuation value and is available with a ST or FC configuration. The Variable attenuator is our newest addition. The In-line type is custom manufactured to meet the length and connector type for the customers needs. Our most popular type is the buildout male to female type attenuator.  Available in all fiber modes and connector types.

Types of Attenuators

  1. Fixed (Fixed attenuators are usually in increments of 5, 10, 15 and 20 dB)

  2. Variable (Typically variable attenuators will operate from 0 to 65 dB)

Fixed fiber optic attenuators are used to reduce the optical power signal in communication links. They work analogous to a step-down transformer. As the signal approaches a device or node in a communication link the power is reduced to a level that is suitable for its application. Communication links such as LAN, CATV and telecommunication networks use fixed fiber optic attenuators.

Variable fiber optic attenuators offer a range of attenuation values. They are used for testing and measurement, or when you need to equalize the power between different signals.

Attenuation

Attenuation, measured in decibels (dB), is a value used to describe the ratio of input power to output power. The value is equal to ten times the logarithm of input power over output power.

Methods of Attenuation

  • Fiber optic attenuators use several methods of attenuation including air gaps, microbends, acousto-optic modulators, and electro-optic modulators.

  • Air gaps between optical fibers cause light to be reflected because of the change in refractive index.

  • Microbends are sharp curvatures with local axial displacements of a few micrometers and spatial wavelengths of a few millimeters. Microbending can cause significant radiant loss and mode coupling.

  • Acousto-optic modulators use sound waves to modify the amplitude, frequency, or phase of light passing through an acousto-optic material.

  • Electro-optic modulators use an electric field to alter the characteristics of light passing through an electro-optic material.

Attenuator Performance

Fiber optic attenuators are characterized by a wavelength range and attenuation range.

Wavelength

The electromagnetic spectrum is the full bandwidth of all wavelengths. What we refer to as the visible spectrum is a range of light waves that can be detected by the human eye. Fiber optic systems transmit light waves from the far visible region, red (650nm), to the near infrared region (1700nm). This range is used due to characteristics of the transport medium, the optical fiber. Shorter wavelengths are attenuated due to scattering of the light source and absorption bands at certain frequencies further attenuate the signal. 

Applications

  1. Receiver padding

  2. System testing

  3. Bit Error Rate testing

  4. Power meter calibration
