Can This New Metric Accurately Measure Your Fiber Attenuator’s Signal Loss?

Fiber optic communication is considered ideal for data transmission over long distances. A fiber optic system uses lightwave technology for data transmission by transforming electrical signals into light pulses. It has exceptional features such as small bandwidth, long-distance signal transmission, lightweight, low attenuation, and large bandwidth. These characteristics make this system a significant contributor to communication in telecommunication infrastructure. Several fiber optical types of equipment are used, like fiber optic attenuator, fiber optic pigtails, and more. 

Before we move to the new metric of fiber attenuation measurement, let's focus a little on fiber optic communication.

Nevertheless, let's begin with the new metric for fiber attenuation.

The New Metric For Fiber Attenuation

The technology world is marked by dynamism. Everyday discoveries and innovations result in a new theory or apparatus that further contributes to technological advancement. Similarly, these advances further lead to a new development in fiber optical technology. 

The Latest News Is About Fiber Attenuation

Fiber attenuation is a crucial physical aspect of the fiber optical system. Earlier, maximum individual fiber cable attenuation was considered the standard metric for measuring fiber attenuation. However, the evolution of fiber optic technology has significantly changed the values of fiber attenuation and the actual fiber loss. That means, a new and more representative metric is required to calculate fiber attenuation. Here, the new metric is a practical way to measure fiber attenuation.

What Is Fiber Attenuation?

Fiber attenuation refers to the loss of signal strength during transmission. It is caused due to two factors, intrinsic and extrinsic. Intrinsic factors are scattering, absorption and bending, whereas extrinsic factors contributing to attenuation can be splices, splitters, and connectors. The purpose of attenuation is to determine the maximum distance an optical fiber can transmit the signal. At present, maximum individual fiber attenuation is used as a metric to calculate the performance of fiber attenuation. It is a recognized standard used by manufacturers and industries.

However, over the last few years, there has been a series of improvements in measurement systems of optical fiber systems and cable performance. Due to this, the actual individual fiber attenuation is different from the specified maximum individual fiber attenuation, which makes the maximum performance of an optical link unachievable. Therefore, fiber optic technology needs a new metric to precisely define fiber optic attenuation.

Link Design Attenuation

The new metric is Link Design attenuation. It gives a more accurate specification of fiber attenuation and can further optimize the network design.

You can determine its value by using 20 spans of fibers to comply with the existing standards. In addition, Monte Caro simulation considers the usage of eight spans as sufficient to achieve a stable state of link design attenuation. Plus, increasing the span number does not produce as significant capability increment as the fewer spans do. Compared to Maximum Fiber Attenuation, link design attenuation offers added advantages such as– high performance, longer regeneration distance, etc.

Conclusion

The above information does not limit the efficacy of maximum fiber attenuation. It is still used for achieving the full performance of fiber optical systems. However, the new metric–link design attenuation can accurately determine the loss budget during transmission and further improve the performance of optical links. It acts as a good metric for measuring the performance of the network design.
