An apparatus includes a cage structure and a cooling plate configured to contain a cooling liquid to cool the cage structure. The cage structure has a front end, a top surface adjacent to the front end, a first opening at the front end, and a second opening on the top surface. The first opening is configured to receive a pluggable optical module. The cooling plate is disposed on top of the second opening of the cage structure. The apparatus may further include a deformable pad disposed at the second opening of the cage structure and beneath the cooling plate.

Liquid cooled optical cages for optical modules

A pass-through connector is provided in one example and includes a first groove to be coupled to a power supply bus bar; a second groove to be coupled to a power return bus bar; and a plurality of electrical pins disposed on a surface of the connector and configured for interfacing with a circuit board, which is coupled to a line card power connector that is configured to receive a line card.

Connector for providing pass-through power

A method includes delivering an electrical signal over an electrical conductor to a transmitter module, which includes a memory holding compensation values corresponding respectively to different conductor lengths. One or more of the compensation values is retrieved from the memory of the transmitter module, and a waveform of the electrical signal is modified responsively to the retrieved compensation values. The electrical signal having the modified waveform is transmitted using the transmitter module over a communication link.

Programmable signal emphasis for optical transmitters

Methods and apparatus for enabling a protected circuit path to be created efficiently are disclosed. In accordance with one embodiment of the present invention, a method for creating a protected circuit path within an optical network system includes identifying a first node, a second node, and a third node. Once the nodes are identified, a pseudo link or a virtual link may be created between the second node and the third node. A first circuit path is then routed between the first node and the second node, and a second circuit path which protects that first circuit path is routed between the first node and the third node using the pseudo link.
