Heat-swap device and method

摘要

A TOSA can include: a light emitting element; and one or more heating elements thermally coupled to the light emitting element so as to provide a substantially constant heat generation profile and/or temperature profile across the TOSA during a light emitting element dormant period and a light emitting element firing period. The TOSA can include a controller operably coupled with the one or more heating elements so as to control the substantially constant heat generation profile and/or temperature profile. In one aspect, the one or more heating elements can include one or more dedicated heating elements. In one aspect, the one or more of the dedicated heating elements can include a resistor element or coil.

1. A transmitting optical sub-assembly (TOSA) comprising:
a light emitting element; a plurality of TOSA components; a plurality of thermal elements thermally associated with the plurality of TOSA components, the plurality of thermal elements configured to provide a substantially constant heat generation profile and/or temperature profile across the TOSA during a light emitting element dormant period and a light emitting element firing period; a controller operably coupled with the one or more thermal elements so as to control the substantially constant heat generation profile and/or temperature profile; and wherein the TOSA has a constant heat generation profile and/or temperature profile with respect to the light emitting element and one or more TOSA components during the light emitting element dormant period and the light emitting element firing period.
