Using Fiber Optic Attenuators with Doped Fiber has many Benefits

Fiber optic attenuators are utilized in networking applications where an optical signal is just too strong and wishes to be reduced. 

There are many applications where this arises, like wanting to equalize the channel strength during a multi-wavelength system or reducing the amplitude to satisfy the input specifications of an optical receiver. In both scenarios, reducing the optical signal strength is important alternatively system performance issues may arise. MPO tester is useful.

Taken by optical attenuators, many firms may be the 2 basic sorts of fiber optic attenuators that are variable and fixed. During this article, we'll specialize in the fixed type.

The further classification of fixed attenuators is

• In-line patch cord
• Build - out style

Approximately 1.25 inches is the size of the build-out attenuator. Many have a male interface connector at one end and a female interface connector at the opposite end but female to female interface connectors also are available. You can buy return loss tester online. The fabrication of the build-out style is usually accomplished using an air gap attenuation or doped fiber attenuation.

The loss of optical power can be accomplished by Air gap attenuators with the assistance of two fibers that are separated by air to yield the loss. These attenuators are often variable or fixed, but to dust contamination, the downside is that they will be susceptible and also are susceptible to change moisture and temperatures. One must even be cautious where they're used. For instance, multi-channel analog systems, like ones employed by CATV, this a variable optical attenuator can create second-order distortions that reduce the performance of the system.

As the name suggests, alongside metal ion doping, doped fiber attenuators contain a little fiber piece that provides the precise interfaces and attenuation in between male and female connections on the attenuators. These types are often wavelength sensitive due to their fabrication. The first reasons, why these doped fiber attenuators are preferred, include:

Provide a stable performance over wide bandpasses and wavelength variations.

Not vulnerable to dirt, moisture, or temperature variations
