Abstract
We supply highly reliable optical components such as Optical Isolators, Circulators, and Filters used in optical submarine repeaters. The Faraday rotator, a key device in optical Isolators, is manufactured from crystals, which also enhances the reliability of our products.
Last year we reported that our standard optical isolator YD-460 withstands the LEO satellite environment (radiation exposure, thermal vacuum cycling) and showed no laser-induced degradation up to 4.8 W at 1.48 µm (Raman pump).
In this work, the laser durability was evaluated with a high-power 1.55 µm source (max. 10 W), the wavelength actually used in satellite optical communication. Optical Isolator showed sufficient durability, and the effect of a heat-radiating housing was also confirmed.
We are engaged in development with the aim of expanding our Optical Components into the new field of Space.
