Optical Adhesives Adhesives for Fiber Array Introducing the adhesives with high moisture resistance and excellent workability for fiber array assemblies V-Groove Fixing / Optical Fiber Fixing Adhesives for Fiber Array Fiber arrays are used for the input and output of optical waveguide devices. As adhesives used for fixing the V-Grooves, AT3727E and AT3728E have realized price reductions while enhancing moisture resistance than conventional products with over 20 years more experience. As adhesives for Optical Fiber fixing, the AT97M and AT8 have gained popularity for their good workability as non-fluid adhesives. High Moisture Resistance and Excellent Durability For a Fiber Array, no peeling after 2,000 hours at 8 C, 8 % humidity. * Our company test results Can Be Polished The adhesives for V-Groove fixing can be polished after assembly. Appropriate for Usage Location makes it Easy to Use The adhesives for fixing V- Grooves have a fluidity, while the optical fiber fixing adhesives are a paste suitable for protecting the fiber.
