Latest Patents

Matsui holds a patent for an "Optical loop back and line test apparatus." This innovative testing apparatus evaluates the performance of optical signal transmissions in the 1.3 µm wavelength region. It operates independently or simultaneously with signal transmission. The apparatus transmits an optical signal in the network direction through a thermo-optic switch. It also loops the signal in the direction of an optical directional coupler. An optical time domain reflectometer generates a test beam at the 1.55 µm wavelength region, which is reflected back to the OTDR in the user-network direction. This allows for simultaneous testing of the transmission cable while maintaining signal integrity.
