Latest Patents

One of Ambe's latest patents is an optical fiber lateral input/output device. This invention aims to enhance the local-light coupling technique, which is crucial for improving work efficiency. The device is designed to minimize interference between an Optical Line Terminal (OLT) and an Optical Network Unit (ONU) while allowing light to leak from a coated optical fiber. This leakage is essential for confirming communication states. The apparatus includes a first jig with a concave portion, a second jig with a convex portion, and a pressing unit that applies force to create a bend in the optical fiber. Additionally, a reflective film is incorporated to manage the leakage light effectively.

Another notable patent is a judgment device and method that determines the state of the terminal end portion of a coated optical fiber. This device utilizes test light with multiple wavelengths to assess the reflection amount at each wavelength, providing insights into the condition of the fiber's terminal end. By measuring Rayleigh backscattered light, the device can also determine return loss, further enhancing the assessment capabilities.
