FA Head Glue 6711
FA head glue refers to the special glue used to fix the optical fiber and V-groove (silicon V-groove) or MT ferrule during FA (Fiber Array) processing.
Description
FA adhesive is a specialized adhesive used to secure optical fibers to V-grooves (silicon V-grooves) or MT ferrules during FA (Fiber Array) fabrication.
Function of FA Adhesive
Fiber Securing: Securely bonds optical fibers to V-grooves or MT ferrules, maintaining high-precision alignment.
Optical Performance: Low shrinkage and low stress prevent misalignment that increases insertion loss.
Reliability: Requires long-term operational stability and resistance to heat, humidity, and aging.
Key Features of FA Adhesive
Low Shrinkage: Shrinkage can cause optical fiber axis misalignment, affecting coupling efficiency.
Low Stress: Prevents bending or positional shifts in the fiber after curing.
Transparency: When light curing is required, the adhesive must exhibit high light transmittance (365nm/405nm bands).
High Temperature and Humidity Resistance: Typically requires passing Telcordia GR-1221/GR-1209 testing.
Moderate bond strength: Strong yet not brittle to prevent cracking during thermal cycling.
