Quad small form factor-double density pluggable transceiver module with heat sink

Abstract

A Quad Small Form Factor-Double Density Pluggable (QSFP-DD) transceiver module which complies with the accepted specifications of the Quad Small Form Factor Pluggable Double Density (QSFP-DD) Multi Source Agreement (MSA) group has a body, a paddle card mounted in the body, and a plurality of conductive fins extending upwardly from top and bottom walls of the body. The QSFP-DD transceiver module isinsertable into a cage and is configured to mate with mating connector in the cage and with a fiber optic cable. The conductive fins do not seat within the cage. The conductive fins dissipate heat generated by convection.

Description

technical field [0001] The present invention relates to the field of input / output (IO) connectors and, more particularly, to a pluggable transceiver module in the form of a Quad Small Form Factor Pluggable Double Density (QSFP-DD) transceiver module suitable for high data rate applications . Background technique [0002] Input / Output (I / O) connectors are commonly used in applications requiring high bandwidth and are often used to provide connections between boxes or racks of computers, routers, and switches. One common form of I / O connector is the Quad Small Form Factor Pluggable Double Density (QSFP-DD) connector. Therefore, this connector includes a transceiver module and a housing defined by standard bodies, so no matter what the supplier is, it can provide reliable performance. [0003] As data rates increase, an insurmountable problem is the physical limitations of the medium used to transmit the signal. For example, passive cables are cost-effective for shorter dist...

Problems solved by technology

[0003] As data rates increase, an insurmountable problem is the physical limitations of the medium used to transmit the signal

For example, passive cables are cost-effective for shorter distances, but as signal frequencies increase, passive cables tend to be limited in distance

Active copper and fiber optic cables are great for transmitting signals over longer distances, but require power and can often create thermal issues if the connector system is not properly designed

However, one of the major concerns with the increased use of active cable assemblies is the increased thermal load of placing such cable assemblies for use on the connector system

Trying to cool a Quad Small Form-Factor Pluggable Double Density (QSFP-DD) transceiver module placed inside the enclosure is relatively challenging
