Abstract
In one embodiment, a module for plugging into a QSFP-DD (Quad Small Form Factor Pluggable Double Density) cage is provided that has one or more projections for contacting a QSFP-DD optical module in an adjacent QSFP-DD recess of the QSFP-DD cage so as to evacuate heat from, and or provide power to, the QSFP-DD optical module.
Claims20
A Quad Small Form Factor Pluggable Double Density (QSFP-DD) optical module arranged to plug into an optical module recess of a QSFP-DD cage, the QSFP-DD optical module comprising:
- an optical interface for interfacing with an optical fibre;
- an electrical interface for interfacing with an electrical interface of the QSFP-DD cage when the QSFP-DD optical module is plugged into the optical module recess of the QSFP-DD cage;
- conversion circuitry for converting at least one of:
- optical signals received at the optical interface from the optical fibre into electrical signals for outputting by the electrical interface, and
- electrical signals received at the electrical interface from the electrical interface of the QSFP-DD cage into optical signals for outputting by the optical interface;
- and
- a shell having a flat portion that is arranged to project outside the optical module recess of the QSFP-DD cage when the QSFP-DD optical module is plugged thereinto, wherein the flat portion has one or more electrical contacts for receiving electrical power and providing the electrical power to the conversion circuitry.
A method for configuring a Quad Small Form Factor Pluggable Double Density (QSFP-DD) optical module, the method comprising:
- providing an optical interface of the QSFP-DD optical module for interfacing with an optical fibre;
- providing an electrical interface of the QSFP-DD optical module for interfacing with an electrical interface of a QSFP-DD cage when the QSFP-DD optical module is plugged into an optical module recess of the QSFP-DD cage;
- providing conversion circuitry for converting at least one of:
- optical signals received at the optical interface of the QSFP-DD optical module from the optical fibre into electrical signals for outputting by the electrical interface of the QSFP-DD optical module, and
- electrical signals received at the electrical interface of the QSFP-DD optical module from the electrical interface of the QSFP-DD cage into optical signals for outputting by the optical interface of the QSFP-DD optical module;
- and
- providing, on a flat portion of a shell that is arranged to project outside the optical module recess of the QSFP-DD cage when the QSFP-DD optical module is plugged thereinto, one or more electrical contacts for receiving electrical power and providing the electrical power to the conversion circuitry.
An apparatus arranged to plug into an optical module recess of a cage, the apparatus comprising:
- an optical interface for interfacing with an optical fibre;
- an electrical interface for interfacing with an electrical interface of the cage when the apparatus is plugged into the optical module recess of the cage;
- conversion circuitry for converting at least one of:
- optical signals received at the optical interface from the optical fibre into electrical signals for outputting by the electrical interface, and
- electrical signals received at the electrical interface from the electrical interface of the cage into optical signals for outputting by the optical interface;
- and
- a shell having a flat portion that is arranged to project outside the optical module recess of the cage when the apparatus is plugged thereinto, wherein the flat portion has one or more electrical contacts for receiving electrical power and providing the electrical power to the conversion circuitry.
