Optical module and optical transmission equipment

1. An optical module comprising:

a housing;

a box type optical subassembly including a bottom portion serving as a heat dissipation face; and

a heat conductive member disposed between the bottom portion of the optical subassembly and a bottom portion of the housing,

wherein the optical subassembly includes

one or a plurality of optical semiconductor devices, and

a temperature controller on which the one or plurality of optical semiconductor devices are mounted and which is placed on an inner bottom portion of the optical subassembly, and

the heat conductive member is disposed only at a portion of the bottom portion of the optical subassembly.

2. The optical module according to claim 1 , wherein an area where the heat conductive member is disposed with respect to the entire bottom portion of the optical subassembly is 15% or more and 55% or less.

3. The optical module according to claim 1 , wherein the heat conductive member is disposed such that power consumption of the optical module at a lower limit of an ambient temperature range with respect to power consumption of the optical module at an upper limit falls within a range of ±10%.

4. The optical module according to claim 1 , wherein

the heat conductive member is any one selected from the group of a heat dissipation grease, a gel for heat dissipation, and a sheet for heat dissipation.

5. An optical transmission equipment comprising the optical module according to claim 1 mounted therein.
