4. The pluggable-modules holder of claim 1 , wherein each of the holder ports is shaped to hold a portion of a respective body of the respective pluggable-module.

5. The pluggable-modules holder of claim 3 , wherein each of the holder ports is further shaped to hold at least a portion of a respective head of the respective pluggable-module.

6. The pluggable-modules holder of claim 1 , further comprising an alignment feature including at least one of a rod and a bore that mates with a corresponding feature of a rack-mounted unit.

7. The pluggable-modules holder of claim 1 , further comprising a plurality of cooling holes extending through the holder body.

8. The pluggable-modules holder of claim 1 , wherein the plurality of holder ports are spaced such that the pluggable-modules holder is configured to hold pluggable-modules associated with multiple rack-mounted units received in a carrier.

9. A module assembly comprising:

a plurality of pluggable-modules, each pluggable module including a pluggable transceiver;

a rack-mounted unit including a plurality of unit ports that receive the plurality of pluggable-modules; a pluggable-modules holder including a holder body and a plurality of holder ports, each of the holder ports being positioned along the holder body, positioned in the holder body to align with a respective unit port, and sized to hold a portion of a respective pluggable-module, the pluggable-modules holder comprising electrical connectors for relaying at least one of control signals and power from one or more of the rack-mounted unit and a fan module associated with the module assembly.

10. The module assembly of claim 9 , wherein the holder body is configured to connect to the rack-mounted unit, directly or indirectly, before or after the plurality of pluggable-modules are inserted into the plurality of holder ports.

11. The module assembly of claim 9 , further comprising alignment features including a rod and a bore that align the pluggable-modules holder relative to the rack-mounted unit to align the plurality of holder ports with the plurality of unit ports.

12. The module assembly of claim 9 , wherein the pluggable-modules holder further comprises one or more retention features that restrain the plurality of pluggable-modules in at least a removal direction of the plurality of pluggable-modules when inserted into the plurality of holder ports, the one or more retention features including at least an assembly of a retention rod extending across a length of the pluggable-modules holder, retention arms extending from the retention rod, and a retention switch that moves the retention rods and retention arms into a retention position such that the retention arms overlap with the plurality of holder ports.

13. The module assembly of claim 9 , wherein the pluggable-modules holder further comprises cooling holes extending through the holder body such that cooling air blown by the fan module passes therethrough.

14. A method for assembling a module assembly, comprising:

providing a pluggable-modules holder comprising a holder body, and a plurality of holder ports, each of the holder ports being positioned along the holder body and sized to hold a portion of a respective pluggable-module the pluggable-modules holder comprising electrical connectors for relaying at least one of control signals and power from one or more of the rack-mounted unit and a fan module;

inserting a plurality of pluggable-modules into the plurality of holder ports such that each of the plurality of pluggable-modules is received by a respective holder port; and

connecting the pluggable-modules holder, directly or indirectly, to a rack-mounted unit such that the plurality of holder ports each align with a respective one of a plurality of unit ports of the rack-mounted unit,

wherein each of the plurality of pluggable-modules mate with a respective unit port.

15. The method of claim 14 , wherein the pluggable-modules holder is connected to the rack-mounted unit before the plurality of pluggable-modules are inserted into the plurality of holder ports.

16. The method of claim 14 , wherein the pluggable-modules holder is connected to the rack-mounted unit after the plurality of pluggable-modules are inserted into the plurality of holder ports such that the plurality of pluggable-modules mate with the plurality of unit ports simultaneously while the pluggable-modules holder is being connected to the rack-mounted unit.

17. The method of claim 14 , wherein the pluggable-modules holder is connected to the rack-mounted unit via a carrier.

18. The method of claim 14 , wherein the pluggable-modules holder is connected to a rack prior to being connected to the rack-mounted unit such that the pluggable-modules holder is a backplane for an assembly of the pluggable-modules holder, the rack-mounted unit, and the pluggable-modules.
