First Claim
Patent Images
1. A closure comprising:
- a base having a bottom wall extending along a length between opposite first and second ends and along a width between opposite first and second sides, the base also including a sidewall extending along a height between the bottom wall and an open top of the base to define an interior, the sidewall extending from the opposite ends of the bottom wall and from the opposite sides of the bottom wall, the length being larger than the width, and the width being larger than the height;
a cover removably coupled to the base to selectively cover the open top of the base to close the interior, the cover and the base being configured to environmentally seal the interior;
a cable port disposed at a periphery of the base to provide cable access to the interior of the base;
a circuit board carried by the base, the circuit board including active components;
a plurality of thermally conductive pads carried by the base at the bottom wall, the pads being positioned to align with at least some of the active components on the circuit board, the pads extending inwardly into the interior to contact the at least some of the active components; and
cooling structures disposed at an exterior surface of the base, the cooling structures increasing a surface area of the exterior surface.

Abstract
A closure (100) facilitates upgrading a network to extend optical fibers closer to, or all the way to, the subscribers by facilitating the transition between optical signals to electrical signals. The closure includes a base (110) and a cover (120) defining an interior; and a circuit board (130) disposed within the interior. A management tray (140) can be coupled to the base. The circuit board (130) includes the optoelectronic circuitry. The management tray (140) includes a platform (141) disposed between the circuit board (130) and the cover (120). Various types of fiber and electrical cable sub-assemblies (160) can be received at a port (113) defined in the closure.
