Fiber Optic Attenuators

Amphenol Broadband Solutions offers a complete line of quality fiber optic attenuators.

Attenuators are used to reduce optical power levels when too much light would overload the fiber optic receivers. In order to achieve the best bit error ratio (BER), the optical power must be maintained within the dynamic range of the receiver. Amphenol Broadband Solutions fiber optic attenuators fit the requirement perfectly. Attenuators absorb extra light energy and protect fiber optic receivers from being overloaded. Amphenol Broadband Solutions attenuators do not reflect the light but instead they absorb the extra light without being damaged. Commonly known as bulkhead connectors, these attenuators have 1 male and 1 female end and have an actual operation wavelength between 1200 – 1600nm.
