Optical communication module

摘要

An optical communication module according to an aspect of this invention includes: a module casing; a conversion element housed in the module casing, and performing at least one of conversion from an electric signal to an optical signal and conversion from an optical signal to an electric signal; a signal processing circuit element performing signal processing, which is housed in the module casing and connected to the conversion element; and a heat conduction member, which contacts the module casing and the signal processing circuit element when a temperature of the atmosphere in the module casing is above the operational temperature range of the signal processing circuit element, but which parts from the signal processing element when a temperature of the atmosphere in the module casing is below the operational temperature range.
