Comparison between Fiber and Cable Filling Paste

Comparison between Fiber and Cable Filling Paste

I. Application

Fiber filling paste : It is mainly used to protect optical fibers from water vapor erosion and mechanical stress, and to play a lubricating and buffering role.

Cable filling paste: Mainly used for waterproof sealing, insulation protection and extending cable life

II. Function

1. Fiber filling paste

• Waterproof seal: Block water vapor intrusion to prevent the performance of optical fiber from deteriorating due to moisture.
• Lubrication protection: Reduce the friction between the optical fiber and the sleeve to avoid micro-bending loss of the optical fiber.
• Temperature adaptability: Can remain stable in a wide temperature range of -40℃ to 70℃

2.Cable filling paste

• Water and moisture resistance: prevent moisture penetration through expansion or adsorption.
• Insulation enhancement: improve cable insulation performance and reduce leakage risk.
• Mechanical protection: fill gaps, buffer external impact, and prevent cable deformation.
