Optical interface cards, assemblies, and related methods, which may be suited for installation and use in antenna system equipment, are disclosed. In certain embodiments, an optical interface card (OIC) comprising a printed circuit board (PCB) having at least one optical sub-assembly (OSA) mounted to at least one first opening end of the PCB and extending into at least one opening and related methods are disclosed. In other embodiments, optical interface assemblies comprised of two OICs mounted together are disclosed. In other embodiments, a communications equipment enclosure including at least one fan configured to draw in air from a first side of the communications equipment enclosure into a lower plenum and across a plurality of communications components into an upper plenum to provide air cooling are disclosed. In another embodiment, a modular distributed antenna system assembly is disclosed.
1. An optical interface card, comprising: a printed circuit board (PCB) having a first perimeter including a first end and a second end opposite the first end;at least one opening disposed in the PCB between the first end and the second end of the PCB and having a second perimeter including at least

An optical interface card, comprising: a printed circuit board (PCB) having a first perimeter including a first end and a second end opposite the first end;at least one opening disposed in the PCB between the first end and the second end of the PCB and having a second perimeter including at least one first opening end and at least one second opening end opposite the at least one first opening end, wherein the second perimeter does not extend to the first perimeter; andat least one optical sub-assembly (OSA) mounted to the at least one first opening end and extending into the at least one opening. 2. The optical interface card of claim 1, wherein the at least one opening does not extend to the first end of the PCB. 3. The optical interface card of claim 2, wherein the at least one OSA does not extend to the first end of the PCB. 4. The optical interface card of claim 1, wherein the at least one OSA is comprised of at least one of a transmitter OSA (TOSA) and a receiver OSA (ROSA). 5. The optical interface card of claim 1, further comprising at least one electrical conductor extending in a substantially straight line from an end of the at least one OSA and electrically connected with one or more printed traces on the PCB. 6. The optical interface card of claim 1, wherein the at least one opening is comprised of at least one rectangular opening. 7. The optical interface card of claim 1, further comprising at least one optical fiber routing guide configured to route one or more optical fibers connected to the at least one OSA. 8. The optical interface card of claim 1, further comprising a mounting plate mounted to the first end of the PCB in a plane orthogonal to a plane of the PCB. 9. The optical interface card of claim 8, further comprising at least one alignment block mounted in at least one opening disposed in the PCB proximate the first end of the PCB and at least one opening disposed in the mounting plate to align the PCB to the mounting plate. 10. The optical interface card of claim 9, further comprising at least one guide pin disposed in the at least one alignment block engaged with the at least one opening disposed in the PCB. 11. An optical interface assembly, comprising: a first optical interface card (OIC) having a first perimeter including a first end and a second end, comprising: at least one first opening between a first end and a second end of the first OIC having a second perimeter including at least one first opening end, wherein the second perimeter does not extend to the first perimeter; andat least one first optical sub-assembly (OSA) mounted to the at least one first opening end and extending into the at least one first opening; anda second OIC, comprising: at least one second opening between a first end and a second end of the second OIC having at least one second opening end; andat least one second OSA mounted to the at least one second opening end and extending into the at least one second opening; andat least one standoff disposed between the first OIC and second OIC. 12. The optical interface assembly of claim 11, wherein the at least one first opening does not extend to the first end of the first OIC, and wherein the at least one second opening does not extend to the second end of the second OIC. 13. The optical interface assembly of claim 12, wherein the at least one first OSA does not extend to the first end of the first OIC, and wherein the at least one second OSA does not extend to the first end of the second OIC. 14. The optical interface assembly of claim 11, wherein the at least one first OSA and the at least one second OSA are each comprised of at least one of a transmitter OSA (TOSA) and a receiver OSA (ROSA). 15. The optical interface assembly of claim 11, further comprising at least one electrical conductor extending in a substantially straight line from an end of the at least one OSA and electrically connected with one or more printed traces on the PCB. 16. The optical interface assembly of claim 11, further comprising a mounting plate mounted to the first end of the first OIC and the first end of the second OIC in a plane orthogonal to a plane of the first OIC and a plane of the second OIC. 17. A method of assembling an optical interface card, comprising: providing a printed circuit board (PCB) having a first perimeter including a first end and a second end opposite the first end, and at least one opening having a second perimeter including at least one first opening end, wherein the second perimeter does not extend to the first perimeter; andmounting at least one optical sub-assembly (OSA) to the at least one first opening end of the at least one opening disposed in the PCB between the first end and the second end of the PCB. 18.
