Gel is a substance used in cables to provide protection, insulation, and support. It is typically found surrounding a single fiber, or multiple fibers that are enclosed in a loose buffer tube. This gel is similar to petroleum jelly in viscosity, and it has several key benefits.
First, the gel helps to protect the fiber or fibers by shielding them from dust, dirt, moisture, and other environmental factors. This ensures that the fiber is safe from damage and that the cable is able to maintain its integrity over time.
Second, the gel provides insulation for the fiber or fibers, which helps to reduce electrical interference and noise. This improves the overall performance of the cable by ensuring that the signal is transmitted clearly and without any distortion.
Third, the gel provides support for the fiber or fibers, helping to keep them secure in the loose buffer tube. This reduces the likelihood of fibers becoming tangled or damaged, and it helps to maximize the life of the cable.
Finally, the gel can also help to reduce cable friction and drag. This makes it easier to run the cable through tight spaces, and it also prevents the cable from becoming frayed or damaged during installation.
Overall, gel is an important part of cables, and it serves several key functions. It helps to protect the fiber or fibers, provides insulation, offers support, and it reduces friction and drag. These qualities make gel an invaluable part of any cable installation, and it is essential for maintaining the cable’s performance and integrity over time.
