for adhesives of optical communication, has developed
for sale resins with a high refractive index of 1.6.
For the high refractive index resins, by adding high
refractive index fillers as in the photo on the right, we
are able to manufacture resins with a refractive index
of 1.9.
These resins are aimed at usage in the fields of optical
recording, display technology, optical energy uses, etc.

V-Groove Fixing / Optical Fiber Fixing
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 AT9575M and AT8105 have gained popularity for their good workability as non-fluid adhesives.

Adhesives forOptical Waveguides
In order to achieve high reliability,
a product must clear the tests conducted
by the users themselves. If you have had
even just a bit of dissatisfaction in
reliability test results, please put NTT-AT’s
adhesives to the test.
We will also offer consulting regarding
adhesion related issues.
