Adhesives for Optical Waveguides

Viscosity 70->20,000 mPas; Shear Bond Strength > 69->200 kgf/cm²; Bending Adhesion Strength 9-25 kgf/cm²; UV Curing Conditions 10-100 mW/cm², 5, 10 min; Colour Light Yellow, Colourless, White; Tg +42-+219 °CNTT Advanced Technology Corporation’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 Advanced Technology Corporation’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 Advanced Technology Corporation’s AT9575M (epoxy) and AT8105 (acrylate) adhesives for optical fiber fixing have gained popularity for their good workability as non-fluid adhesives.NTT Advanced Technology Corporation 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.In case you need any consulting regarding issues related to adhesion, please contact the AMS Technologies optical adhesives experts to discuss the detailed challenges of your application.Key Features:Excellent DurabilityJust the Right Viscosity for Easy Application: Non-liquid Viscosity for Fiber Fixation, Low Viscosity Fluid for Fiber Fixation into V-Type GrooveHeat-proof: Maximum Glass Transition Temperature Tg of Over +200 °C (AT3925M)Viscosity: 70 to >20,000 mPasShear Bond Strength: > 69 to >200 kgf/cm²Bending Adhesion Strength: 9 to 25 kgf/cm²UV Curing Conditions: 10 to 100 mW/cm², 5, 10 minColour (Pre-Curing): Light Yellow, Colourless, WhiteGlass Transition Temperature Tg: +42 to +219 °CApplications: Gluing of Fiber Array Assemblies; V-Groove Fixing; Optical Fiber Fixing

5 inch Disc; Silicon Dioxide; Ceramic Ferrule; no PSAThe ADS film can be used for final polishing for optical fiber connector end-face.The ADS film offers longer life cycle for the optical connector polishing.NTT Advanced Technology Corporation’s ADS series of final polishing films is ideal for the final polish of optical connector end faces and offers longer polishing life cycles. These films polish the end face of an optical connector without scratches, residues or contamination on the ferrule end face.ADS-NEXT polishing films feature stable polishing force while maintaining final finish performance and achieving an extended life-span. This series of final polishing films attains a high-performance polish with distilled water. Another feature of the ADS-NEXT series is a sharp improvement in the indentation problems that occur especially in 1.25 mm diameter ferrules from repeated use polishing. Even after many usages, ADS-NEXT can still protect against sudden occurrences of fiber indentation.ADS-MPO series is a new generation of polishing films that has been improved for MPO connector end faces to realize a finishing quality equivalent to that of single fiber polish, leaving no scratches or dirt while at the same time their stable polishing power ensures long life. These films can polish to a convex shape to eliminate dips in the core (Coredip value of “0”) which particularly affects the optical characteristics (IL/RL) of multi mode fiber. APS-MPO final polishing films also realize low return loss, comparable to single connectors, by suppressing subsurface damaged layer to a minimum. With a base thickness of 75 µm, they are available in disc and sheet types.Key Features:Ideal for Final Polish of MPO Optical Connector End FaceHigh Stability and Long Product LifetimePrevents Excessive Fiber Undercut after Repeated Use (ADS/ADS-NEXT)Multi Mode Fiber Coredip Value of “0” (ADS-MPO)Low Return Loss Comparable to Single Mode Fiber Connectors (ADS-MPO)Compatible with 1.25, 2.5 mm Diameter Zirconia Ferrules (ADS/ADS-NEXT), MPO Ferrule, All Types (ADS-MPO)Compatible with Multi Mode (OM1/2/3/4, GI50/62.5, etc.) and Single Mode (OS1/2, SM, etc.) Fiber (ADS-MPO)Disc Type (5.0 inch, 127 mm Diameter), Sheet Type (5.5 x 5.5 inch, 140 x 140 mm, ADS-MPO) and Roll Type (5.5 inch, 140 mm x 12 m, ADS/ADS-NEXT) AvailableApplications: Final Polish of Fiber Connector End Face
