FOC plans to display samples of this product at OFC 2016, which is scheduled to take place from March 22 to 24 in Anaheim, California, USA.
(*1) The transmission method which bundles 2 carriers (wavelengths) modulated with different data.
(*2) Acronym for Dual-Polarization Quadrature Phase Shift Keying. A method of phase modulation for digital signals in which 2 bits of data are allocated to each of 4 modulated optical phases (0, 90, 180, 270°) for both P-polarized and S-polarized light.
(*3) Acronym for Dual Polarization-x Quadrature Amplitude Modulation. A method of phase modulation for digital signals where multiple bits of data are allocated to modulated optical amplitudes and modulated optical phases for both P-polarized and S-polarized light.
(*4) Acronym for Planar Lightwave Circuit. Optical circuit on a silicon chip or quartz substrate containing optical waveguides with accuracies on the order of an optical wavelength
(*5) Optical mixer component that is used for coherent signal demodulation purposes in heterodyne and intradyne detection systems. The hybrid mixes the incoming optical data signal with an optical reference source and guides the combined signal to the balanced receivers.
(*6) A receiver consisting of two photodiodes which receive differential optical output from 90° Hybrids. Improved receiver characteristics are achieved by using the difference between the two photodiode currents.
(*7) Acronym for Variable Optical Attenuation function. Function to variably attenuate the optical signal strength. Adjusting the attenuation amount in accordance with the received optical signal strength allows for acceptance of a wide dynamic range of optical input power.
(*8) Converts the received optical signal to an electrical signal in the optical receiving section after combining the received optical signal with a local reference light. The waveform distortion that occurs in the optical transmission path is then compensated for by digital signal processing. This technique allows for significant reduction in system cost through the elimination of optical dispersion compensators and optical amplifiers for loss compensation.
