Hardened optical platform with pluggable optics
A hardened optical platform includes a hardened enclosure including a door that when closed environmentally seals the hardened enclosure; a first set including one of more modules; a second set including one or more modules arranged substantially perpendicular to the first set; and high-speed cabling interconnecting the first set to the second set, wherein the hardened optical platform is passively cooled with the hardened enclosure and the door being weatherproof thereby having no airflow internally from a surrounding environment.
1. A hardened optical platform comprising:
a hardened enclosure including a planar rear surface having an inside within the hardened enclosure and an outside exposed to an outside environment outside of the hardened enclosure, a door that when closed environmentally seals the hardened enclosure, and heat fins disposed on the outside of the planar rear surface in the outside environment outside of the hardened enclosure;
a first set of one or more modules disposed in one or more housings disposed within the hardened enclosure, each housing including a planar rear thermal contact surface that is enlarged relative to a remainder of the housing; and
high-speed cabling interconnecting the first set of one or more modules to a second set of one or more modules,
wherein the first set of one or more modules is passively cooled with the hardened enclosure by the enlarged planar rear thermal contact surface of each of the one or more housings directly abutting and making a direct surface-to-surface thermal contact with the inside of the planar rear surface of the hardened enclosure within the hardened enclosure opposite the heat fins disposed on the outside of the planar rear surface of the hardened enclosure in the outside environment and the door being weatherproof thereby having no airflow internally from a surrounding environment.

17. The hardened optical platform of claim 1 , further comprising a temperature sensor and circuitry configured to heat an interior of the hardened enclosure responsive to a predetermined temperature.
18. The hardened optical platform of claim 1 , wherein each of the first set of one or more modules comprises a printed circuit board sandwiched between a first side and a second side of each of the one or more housings adjacent to the planar rear thermal contact surface.
19. The hardened optical platform of claim 1 , wherein the heat fins move heat received from each of the first set of one or more modules and the planar rear thermal contact surface of each of the one or more housings through the planar rear surface of the hardened enclosure to the surrounding environment via convection.
20. A method comprising providing a hardened optical platform that includes
a hardened enclosure including a planar rear surface having an inside within the hardened enclosure and an outside exposed to an outside environment outside of the hardened enclosure, a door that when closed environmentally seals the hardened enclosure, and heat fins disposed on the outside of the planar rear surface in the outside environment outside of the hardened enclosure;
a first set of one or more modules disposed in one or more housings disposed within the hardened enclosure, each housing including a planar rear thermal contact surface that is enlarged relative to a remainder of the housing; and
high-speed cabling interconnecting the first set of one or more modules to a second set of one or more modules,
