Method of cooling stacked, pluggable optical transceivers
An optical transceiver cooling assembly includes stacked cages mounted to a PCB. A heat radiator also is mounted on the PCB. Cooling devices (e.g., heat pipes) are coupled to the heat radiator and at least one of the cages. In some embodiments, the cages may include a divider that extends beyond the cage and is coupled to at least one of the cooling devices outside the cage. In some embodiments, the cooling devices extend into the cage and may be coupled together.
