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. ## Claims ### Claim 1 (canceled) ### Claim 2 A closure comprising: a base extending along a length between opposite first and second ends, along a width between opposite first and second sides, and along a height between a bottom and an open top, the length being larger than the width, and the width being larger than the height, the first and second ends cooperating with the first and second sides to define a periphery around the housing extending between the bottom and the open top; a cover that cooperates with the base to define an interior, the base being removably coupled to the base to selectively cover the open top of the base to close the interior, the cover and base being configured to environmentally seal the interior; a cable port disposed at the periphery of the base to provide cable access to the interior of the housing; 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, 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 last some of the active components; and cooling structures disposed at an exterior surface of at least one of the base and the cover, the cooling structures increasing the surface area of the exterior surface. ### Claim 3 (depends on 2) The closure of claim 2, wherein the cooling structures include parallel channels extending across the exterior surface. ### Claim 4 (depends on 2) The closure of claim 2, wherein the cooling structures include raised shapes formed at the exterior surface. ### Claim 5 (depends on 4) The closure of claim 4, wherein the raised shapes include pyramid shapes. ### Claim 6 (depends on 4) The closure of claim 4, wherein the raised shapes include frustro-conical shapes. ### Claim 7 (depends on 2) The closure of claim 2, wherein the cooling structures include recessed shapes formed at the exterior surface. ### Claim 8 (depends on 7) The closure of claim 7, wherein the recessed shapes include pyramid shapes. ### Claim 9 (depends on 7) The closure of claim 7, wherein the recessed shapes include frustro-conical shapes. ### Claim 10 (depends on 2) The closure of claim 2, wherein the thermally conductive pads are formed of a different material than the base. ### Claim 11 (depends on 2) The closure of claim 2, wherein the thermally conductive pads are formed of a common material with the base, the pads being thicker than the base. ### Claim 12 (depends on 2) The closure of claim 2, wherein the base is formed of a thermally conductive material. ### Claim 13 (depends on 2) The closure of claim 2, wherein the cover is formed of a thermally conductive material. ### Claim 14 (depends on 2) The closure of claim 2, further comprising a cable assembly that couples to the base at the cable port, the cable assembly including an electrical cable that extends into the interior at the cable port. ### Claim 15 (depends on 14) The closure of claim 14, wherein the electrical cable is one of a plurality of electrical cables of the cable assembly. ### Claim 16 (depends on 14) The closure of claim 14, further comprising a sealing arrangement that mounts over the electrical cable, the sealing arrangement being configured to provide an environmental seal between the interior and an exterior of the closure. ### Claim 17 (depends on 16) The closure of claim 16, wherein the sealing arrangement environmentally seals to an exterior of the electrical cable and to the cable port. ### Claim 18 (depends on 17) The closure of claim 17, wherein the sealing arrangement carries an o-ring to seal to the cable port and carries a gasket through which the electrical cable extends. ### Claim 19 (depends on 17) The closure of claim 17, wherein the sealing arrangement is configured to seal an interior of the electrical cable at the cable port. ### Claim 20 (depends on 16) The closure of claim 16, wherein the sealing arrangement is configured to inhibit axial pullout of the electrical cable from the closure. ### Claim 21 (depends on 20) The closure of claim 20, wherein a jacket of the electrical cable is potted to the sealing arrangement.
