Fiber Optic Attenuators


Fiber Optic Attenuators



• 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


When choosing one style of fiber optic attenuator over another, consider attenuation range and wavelength range of the attenuator, as well as resolution and any polarization dependent loss (PDL) requirements.

Some Common Attenuator Types

Fiber Optic Bulkhead Attenuator

Male to Female Attenuator - This attenuator is used with singlemode cable to the strength of the fiber optic signal. Also using high-precision doping technology for low back reflection and increased fiber signal accuracy. Ideal for use in CATV, LAN, WAN, and telecommunications applications.

Fiber Optic Bulkhead Attenuator

Bulkhead Attenuator - This fixed attenuator may incorporate a wavelength-sensitive neutral density filter to achieve attenuation. The female-to-female design typical of this type of attenuator enables it to accept standard male fiber optic connectors on each side of the bulkhead. Bulkhead attenuators are ideal for use in fiber optic patch panels, instrument front panels, and other applications that require a fixed level of attenuation and easy connectivity.

Fiber Optic Clip On Attenuator

Clip On Variable Attenuator - This device works by physically bending fiber optic cable via the use of thumbscrews. It can be attached at any point in a cable, and leaves no lasting effects on the cable whenremoved. Since this type of attenuator does not require connectors, it is a great way to achieve attenuation without producing back reflections.

Fiber Optic Step Attenuator

Step Attenuator - This device creates the desired level of attenuation by creating one, two or three loops or bends in jacketed fiber optic cable. These loops are typically created by placing the cable into recessed paths molded into the body of the attenuator. The housing usually includes a slide-on cover that secures the loops in place. You can place this attenuator anywhere along the length of the cable, and the device can be repositioned or removed with no permanent affects on the cable. No connectors are required.

Fiber Optic Air Gap Attenuator

Air-Gap Variable Attenuator - This type of attenuator enables you to achieve a broad range of attenuation levels by adjusting the space or air gap between two mated fibers. You can use this attenuator to a replace a mating sleeve at the patch panel, where variable attenuation levels can be introduced to the system. Air gap fixed attenuators are also available, which use washers of different thickness to achieve attenuation. The washers are typically placed between two mated connectors at the light source.
