How much do you know about optical cable filling？

Optical cable filling refers to the process of filling the space between optical fibers in a cable with a gel or other material to protect the fibers from damage and reduce signal loss. This process is essential in ensuring the reliability and longevity of optical cables, which are used to transmit data over long distances at high speeds.

The filling material used in optical cables is typically a thixotropic gel that is specifically designed to protect the fibers from moisture, physical damage, and temperature fluctuations. This gel also helps to reduce attenuation or signal loss in the cable, ensuring that the signal strength remains consistent over long distances.

Optical cable filling is a critical step in the manufacturing process of optical cables, as it ensures the proper function and performance of the cable. Proper filling can also improve the lifespan of the cable and reduce the need for costly repairs and replacements.
