Stackable fiber optic transmitter/receiver modules

A method comprising:

• obtaining at least first and second transmitter/receiver modules, each of the first and second transmitter/receiver modules including a housing defining a longitudinal axis and having opposed first and second longitudinal sides extending along the longitudinal axis, and first and second ends, each of the first and second transmitter/receiver modules including first and second interlocking structures disposed on respective first and second longitudinal sides of the housing;
• mounting the second transmitter/receiver module to the first transmitter/receiver module through cooperatively engaging the first interlocking structure disposed along the first longitudinal side of the first transmitter/receiving module and the second interlocking structure disposed along the second longitudinal side of the second transmitter/receiver module such that the first and second transmitter/receiver modules assume a mated condition in stacked coupled relation;
• coupling a first power interface of the first interlocking structure of the first transmitter/receiver to a second power interface of the second interlocking structure of the second transmitter/receiver module to provide electrical power between the first and second transmitter/receiver modules;
• positioning a first signal connector at the first end of the housing of each of the first and second transmitter/receiver modules;
• and
• positioning a second signal connector at the second end of the housing of each of the first and second transmitter/receiver modules.

A fiber optic transport system comprising:

• a plurality of transmitter/receiver modules, each of the transmitter/receiver modules comprising:
• a housing having first and second ends and opposed longitudinal sides between the first and second ends;
• an electrical connector arranged at the first end of the housing;
• a fiber optic connector arranged at the second end of the housing;
• and
• first and second interlocking structures arranged on respective opposed longitudinal sides of the housing, the first interlocking structure having a first power interface and the second interlocking structure having a second power interface;
• wherein the plurality of transmitter/receiver modules are configured to assume a mated condition in stacked coupled relation through cooperative engagement of the first interlocking structure of a first transmitter/receiver module with the second interlocking structure of a second transmitter/receiver module;
• and
• wherein the first and second power interfaces of the respective first and second transmitter/receiver modules are in electrical communication when the first and second transmitter/receiver modules are in the mated condition.
