Specialty Optical Fibers Handbook

Kuzushita et al. [26] reported on the low-temperature modulus properties of

nine coatings and correlated them with the added attenuation observed at

C for fibers coated with four resin types: polyester-polyol–type urethane

acrylate, polyether-polyol–type urethane acrylate, polybutadiene acrylate, and

UV-curable silicone.

The modulus of coating films at cold temperatures was initially determined by

Instron tensile strength testing of films in temperature-controlled chambers. This

process proved fairly time consuming, because of the time required for tempera-

ture equilibration between runs.

The development of dynamic mechanical analyzers gave rise to the exceed-

ingly more efficient dynamic mechanical analysis (DMA) of UV-cured films.

This nondestructive ...
