Abstract

A pluggable module includes a pluggable body extending between a mating end and a cable end. The pluggable body has a first end and an opposite second end with sides extending therebetween along a length of the pluggable body. The first end, second end and sides define a cavity. An internal circuit board is held in the cavity. The internal circuit board is provided at an end of a cable communicatively coupled to the internal circuit hoard. The pluggable body is configured to be plugged into a receptacle assembly such that the internal circuit board is communicatively coupled to a communication connector of the receptacle assembly. The pluggable body includes a plurality of fins extending outward from at least one of the first end, the second end and the sides. The fins are provided proximate to the cable end of the pluggable body.

First claim

What is claimed is:

1. A pluggable module comprising:
a pluggable body extending between a mating end and a cable end, the pluggable body having a first end and an opposite second end with sides extending therebetween along a length of the pluggable body, the first end, the second end and the sides defining a cavity; and
an internal circuit board held in the cavity, the internal circuit board being provided at an end of a cable communicatively coupled to the internal circuit board, wherein the pluggable body is configured to be plugged into a receptacle assembly such that the internal circuit board is communicatively coupled to a communication connector of the receptacle assembly;
wherein the pluggable body includes a plurality of fins extending outward from at least one of the first end, the second end and the sides, the fins run lengthwise between the cable end and the mating end.

2. The pluggable module of claim 1 , wherein the fins run approximately the entire length of the pluggable body between the cable end and the mating end.

3. The pluggable module of claim 1 , wherein the fins are parallel plates.

4. The pluggable module of claim 1 , wherein the fins extend from both sides.

5. The pluggable module of claim 1 , wherein the fins are separated by channels configured to receive rails of the receptacle assembly, the fins engaging the rails to transfer heat from the pluggable body into the rails.

6. The pluggable module of claim 1 , wherein the fins extend lengthwise from inside the receptacle assembly to outside of the receptacle assembly forward of the receptacle housing.

7. The pluggable module of claim 1 , wherein the fins are separated by channels, the channels being open at the cable end to allow airflow along the fins from the cable end toward the mating end.

8. The pluggable module of claim 1 , wherein the fins include end fins extending from the first end and side fins extending from both sides.

9. The pluggable module of claim 8 , wherein at least some of the side fins extend from the end fins.

10. The pluggable module of claim 1 , wherein the fins are positioned along the pluggable body such that the fins are exposed at a port opening of the receptacle assembly.

11. The pluggable module of claim 1 , wherein the pluggable body includes a thickness defined between an interior surface defining the cavity and an exterior surface opposite the interior surface, the fins extending outward from the exterior surface such that edges of the fins are spaced outward from the exterior surface.

12. A pluggable module comprising:
a pluggable body extending between a mating end and a cable end, the pluggable body having a first end and an opposite second end with sides extending therebetween along a length of the pluggable body, the first end, the second end and the sides defining a cavity; and
an internal circuit board held in the cavity, the internal circuit board being provided at an end of a cable communicatively coupled to the internal circuit board, wherein the pluggable body is configured to be plugged into a receptacle assembly such that the internal circuit board is communicatively coupled to a communication connector of the receptacle assembly;
wherein the pluggable body includes a plurality of first end fins extending outward from the first end and the pluggable body including a plurality of side fins extending outward from at least one of the sides, the fins run lengthwise between the cable end and the mating end.

13. The pluggable module of claim 12 , wherein the fins are separated by channels configured to receive rails of the receptacle assembly, the fins engaging the rails to transfer heat from the pluggable body into the rails.

14. The pluggable module of claim 12 , wherein the fins extend from inside the receptacle assembly to outside of the receptacle assembly.

15. The pluggable module of claim 12 , wherein the fins are separated by channels, the channels being open at the cable end to allow air flow along the fins from the cable end toward the mating end.

16. A communication system comprising:
a pluggable module comprising a pluggable body extending between a mating end and a cable end, the pluggable body having a first end and an opposite second end with sides extending therebetween along a length of the pluggable body, the first end, the second end and the sides defining a cavity, the pluggable body having a plurality of fins extending outward from at least one of the first end, the second end and the sides, and the pluggable module having an internal circuit board held in the cavity, the internal circuit board being provided at an end of a cable communicatively coupled to the internal circuit board; and
a receptacle assembly having a receptacle housing defining a module cavity with a port opening at a front end of the receptacle housing open to the module cavity, the front end of the receptacle housing being configured to be positioned within an opening of a faceplate, the module cavity receiving the pluggable module through the port opening, the receptacle assembly having a communication connector within the receptacle housing at a rear end of the receptacle housing, the pluggable module being pluggably coupled to the communication connector such that the internal circuit board is communicatively coupled to the communication connector;
wherein the fins are positioned at the front end such that the fins allow airflow between the module cavity behind the faceplate and an exterior environment forward of the faceplate.

17. The communication system of claim 16 , wherein the receptacle assembly comprises a thermal transport insert in the module cavity, the pluggable module directly engaging the thermal transport insert, the thermal transport insert drawing heat from the pluggable body to cool the pluggable body.

18. The communication system of claim 17 , wherein the thermal transport insert includes grooves formed by rails, the grooves receiving corresponding fins such that the rails are positioned between, and receive heat from, adjacent fins.

19. The communication system of claim 16 , wherein the fins extend from inside the receptacle assembly to outside of the receptacle assembly.
