What dB Loss is in Fiber Cables and How to Prevent It

Learn how to measure and prevent db loss in your fiber cables.

In fiber optics, data is transmitted through light pulses sent through thin glass strands. The performance of these cables is measured in decibels (dB), which indicates how much power the light has when it moves through the cables. The goal is naturally to transmit 100% of the data, so measuring how much of the data may get lost in transit can indicate how well the cables perform. This measurement is called dB loss. Too much light loss leads to failure and signifies that the fiber cable is not up to industry standards. So how can you make sure your fiber cables are not suffering significant dB loss? Read on to learn what causes this loss and measures that can be taken to avoid it. 

How db Loss in Fiber Cables Happens

You should consider dB loss as early as before the installation occurs. Cables built to provide the lowest possible dB loss help ensure the best data transmission. Although these cables might have a higher price point, their durability will make them well worth the cost. 

However, after installation, dB loss may be caused by end-point contamination. Touching connector ends can contaminate the transmission of light by smearing the glass ends with dirt and oil common on fingers. A scope can inspect the cable end faces, and a special cleaner can be used to ensure a pristine surface. If your fiber optic cable is defective, it may just need to be cleaned. Rather than throwing out cables, contact a professional fiber optic cable contractor who has the expertise and tools to carefully examine the fiber cables and return them to a pristine condition. 

Why It is Important to Minimize dB Loss

The power of your fiber optic cables lies in their ability to transmit important information and data cleanly. A mediocre cable or a poor installation of a good one can devalue your data and deprive you of vital high-speed data transmission. 

It is essential then to hire experienced fiber optic cable technicians who can properly install cables and take measures to avoid data loss and network failure. Many organizations consider data to be their most valuable asset. The quickest way to lose this asset is through poor data transmission. By selecting the right cables and installation, you can ensure that your network’s dB loss remains low throughout its lifetime.
