OPTICAL COMMUNICATION MODULE

摘要

PROBLEM TO BE SOLVED: To prevent malfunctions as much as possible by keeping an optical communication module within the operating temperature range without releasing the heat generated by a signal processing circuit element even in a low- temperature environment. SOLUTION: The optical communication module comprises a module housing, a conversion element 6 which is disposed in the module housing and which conducts at least either conversion from an electrical signal to an optical signal or conversion from an optical signal to an electrical signal, a signal processing circuit element 8 which is disposed in the module housing and is connected to the conversion element and conducts signal processing, and a thermal conduction section 10 which is so structured as to be brought into contact with the module housing and the signal processing circuit element when the atmosphere in the module housing exceeds the operating temperature range of the signal processing circuit element, and to be separated from either the module housing or the signal processing circuit element when the atmospheric temperature in the module housing is lower than the operating temperature range.
