Abstract

An optical networking system has connector blocks, each having a series of sockets. Each socket receives an optical transceiver and provides a full EMI shield. An active cooling system has heat pipes for drawing heat from the devices, through the sockets and to a heat exchanger.

Claims (16)

1. A transceiver networking system comprising:

sockets for receiving transceiver devices, the sockets being in a connector block providing an EMI shield, and

the connector block having an active cooling system for heat removal from the devices, the active cooling system including:

a heat sink with fins extending rearwardly from the connector block, the heat sink extending along a length of the connector block; and

heat pipes running along the length of the connector block and interposed between the connector block and the heat sink.

2. A transceiver networking system as claimed in claim 1 , wherein the system comprises a plurality of connector blocks whereby the sockets form a grid in a front face of a housing.

3. A transceiver networking system as claimed in claim 1 , wherein the heat pipes are at the rear of the sockets.

4. A transceiver networking system comprising:

sockets for receiving transceiver devices, the sockets being in a connector block providing an EMI shield, and

wherein the connector block includes an active cooling system for heat removal from the devices, the active cooling system including:

a plurality of heat pipes; and

a heat sink with fins extending rearwardly from the connector block, the heat sink extending along the length of the connector block,

the transceiver networking system further including a line card, which extends underneath the heat sink and is bent upwardly to connect to the sockets or transceiver devices in the sockets.

5. A transceiver networking system as claimed in claim 4 , wherein the line card comprises a series of fingers, each bent upwardly to connect to a socket or transceiver device.

6. A transceiver networking system as claimed in claim 4 , wherein the line card is connected to the sockets or transceiver devices by a connector which is of a high thermal conductivity material for thermal conduction through the socket, the connector, the card and to the cooling system.

7. A transceiver networking system as claimed in claim 6 , wherein the card is of thin material.
