15 August 1984The Development Of Bidirectional-Wavelength-Multiplexing Integrated Module
Bidirectional-wavelength-multiplexing integrated module has been developed includes the. components, indispensable for wavelength-multiplexing technology, in a single package. It has low cost, small size and light weight. Wavelengths of two LEDs are 780 nm and 880 nm. Optical detector is either APD or PD. Optical power and near-end crosstalk attenuation are more than -20 dBm and 40 dB, respectively and insertion loss less than 4 dB. This module is available in various applications.
