By plating, various characteristics such as corrosion resistance, wear resistance, lubricity, conductivity, solderability, heat resistance, antibacterial, etc. can be granted.
A reliability test is a test to see if the characteristics immediately after plating do not change over time. In the field of optical communication, there is also test standard to check whether the light passing through the optical fiber is bad or run into aged deterioration or not.

Telcordia-Generic Requirement Standard
GR-1221 Optical passive components reliability test (Spectral characterization during environmental
screening)

Of course, our plated fiber (called metallized fiber) has been tested and confirmed to have long-term reliability before being offered to the market.

To be adopted in the optical communication industry,
based on these test results, our metallized fiber has been evaluated as having long-term reliability and continues to this day.
Not just smartphones and mobile phones, in this era when various things have begun to be connected to the Internet, as the number of terminals continues to increase, the importance of communication infrastructure also increase. The next-generation communication system that supports such future life is 5G, which is often heard these days.

5G, which is said to be 100 times faster than 4G, will make a breakthrough in "high speed," "large capacity," "low delay," and "simultaneous connection of multiple terminals." This system uses equipment that requires metallized fiber, and our technology contributes to the long-term stable operation of the system.

We plan to continue to provide products for 5G in the future.
