NTT-AT’s series of adhesives for fiber array assemblies feature high moisture resistance and excellent workability for v-groove fixing or optical fiber fixing.
Fiber arrays are used for the input and output of optical waveguide devices. NTT-AT’s AT3925M, AT9390, AT9968, AT3727E and AT3728E epoxy-based optical adhesives are used for fixing the v-grooves and have realized price reductions while enhancing moisture resistance compared to conventional products. These adhesives can be polished after assembly.
NTT-AT’s AT9575M (epoxy) and AT8105 (acrylate) adhesives for optical fiber fixing have gained popularity for their good workability as non-fluid adhesives.
NTT-AT has executed durability tests that have shown no peeling of a fiber array after 2,000 hours at +85 °C and 85% of humidity. With viscosities that are appropriate for the usage location, the adhesives for fiber array assemblies are easy to use. While the adhesives for fixing v-grooves show fluidity, the optical fiber fixing adhesives’ consistency is that of a paste, suitable for protecting the fiber.
