index paste

Indexpaste is used to avoid the reflections between FO conductors in FO connectors.

The index paste is a transparent gel that has the same refractive properties as the core glass and is inserted between the connector transitions. The index paste creates a reflection-free transition between the core glass, gel and core glass.

When calibrating optical fib ers, the index paste also serves to prevent erroneous measurements caused by an unwanted air gap between two optical fiber ends in fiber optic connectors, resulting in attenuation.
