Adhesive Applications in Fibre Optics
To secure fibre-optic cables, fibre arrays and waveguides, Hoenle has developed special adhesives that can allow an unimpeded transmission of light at optical interfaces. To maintain their light transmission properties, they do not yellow or otherwise change in colour with age. These adhesives do not readily absorb moisture and feature a high glass transition (Tg) point and low thermal expansion.
To allow fast curing after adjustment of the fibreglass cables, these adhesives are usually UV-curing, allowing small bonding surfaces to be set and cured within seconds.
Specially formulated Hoenle adhesives are used for joining fibre optic cables and waveguides
The table below lists a selection of adhesives that are suitable for joining, reinforcing and sealing fibre cables, fibre-chip interfaces and fibre arrays. Further products and custom solutions are available on request. To download the technical datasheets (TDS) please click on the adhesive name.
