Optical communication device

摘要

An optical communication device having an optical fiber, other optical parts, a transparent potting resin with a refractive index akin to the fiber and a pressurizing element with extra pressure in contact with the potting resin for applying positive pressure upon the potting resin with a predetermined temperature range. The present optical communication device can solve the problems of decline of sensitivity of PDs and instability of the oscillation of LDs in a low temperature region between -40° C. and 0° C. after a heat cycle test.
