A coolant distribution manifold assembly for use in a module or circuit pack of an optical networking system, including: a body defining a main inlet port at one end, a main outlet port at another end, and a plurality of cooling plate inlet ports and cooling plate outlet ports disposed between the main inlet port and the main outlet port; where the body further defines an upper internal plenum and a lower internal plenum each coupled to one of the main inlet port and the plurality of cooling plate inlet ports and the main outlet port and the plurality of cooling plate outlet ports. Optionally, the upper internal plenum and the lower internal plenum each have a variable cross-sectional area along a length of the body between the main inlet port and the main outlet port.

Dual flow low profile coolant distribution manifold

A network element include one or more modules each supporting one or more pluggable modules; and a first manifold and a second manifold each configured to connect to a conduit associated with a coldplate, wherein one of the first manifold and the second manifold is an inlet manifold and the other is an outlet manifold for a cooling fluid that flows through the conduit to cool the one or more pluggable modules. The one or more pluggable modules can be each a pluggable optical module that is one of compliant to any of XFP, SFP, XENPAK, X2, CFP, CFP2, CFP4, CFP8, QSFP, QSFP+, QSFP28, OSFP, and QSFP-DD and have a housing that has dimensions similar to any of XFP, SFP, XENPAK, X2, CFP, CFP2, CFP4, CFP8, QSFP, QSFP+, QSFP28, OSFP, and QSFP-DD.

Liquid cooling high-density pluggable modules for a network element

A module for multiple network pluggable optics is disclosed. The module includes a Printed Circuit Board (PCB); a faceplate connected to the PCB; a plurality of cage assemblies connected to the PCB, each cage assembly is configured to receive a pluggable optical module via a corresponding opening in the faceplate; and a shared heat exchanger that is integrally formed and substantially covers the plurality of cage assemblies, wherein the shared heat exchanger is configured to cool multiple pluggable optics in the plurality of cage assemblies.

Cooling multiple high-density network pluggable optical modules using a shared heat exchanger

A module for multiple network pluggable optics is disclosed. The module includes a faceplate, a plurality of cage assemblies, and a plurality of springs. The faceplate includes a front face, a first wall extending from the front face, the first wall including a heat exchanger, and a second wall extending from the front face, the second wall being offset from the first wall. The plurality of cage assemblies is positioned at least partially within a volume defined by the front face and the first and second walls. Each cage assembly is configured to receive a pluggable optical module. The plurality of springs are configured with one or more springs positioned between each cage assembly and the second wall to push the plurality of cage assemblies towards the first wall such that each pluggable optical module received into one of the plurality of cage assemblies is pressed against the heat exchanger.
