6. The optical port of claim 5 , wherein N is equal to or greater than two.
7. The optical port of claim 5 , wherein N is equal to or greater than three.
8. The optical port of claim 5 , wherein N is equal to or greater than four.
9. The optical port of claim 5 , wherein said at least one second latching feature of the non-VLF-type optical plug comprises N windows formed in the wall of the plug receptacle and extending thru the inner and outer surfaces of the plug receptacle, and wherein said at least one second latching feature of the optical port is a segmented ridge comprising N ridges disposed on the outer surface of the respective wings, and wherein the N windows engage the N ridges when the non-VLF-type optical plug is mated with the optical port.
10. The optical port of claim 2 , wherein said at least one second latching feature disposed on the outer surface of the receptacle wall of the first port receptacle comprises a plurality of ridges, and said at least one window formed in the wall of the non-VLF-type optical plug comprises a plurality of windows that correspond in number to said plurality of ridges.
11. The optical port of claim 1 , wherein the non-VLF-type optical plug includes a ferrule and a plug receptacle, the plug receptacle including a wall having at least one window that is operative as said at least one second latching feature of the non-VLF-type optical plug.
12. The optical port of claim 11 , wherein said wall defines a cylindrical opening that is coaxial with said ferrule and has a diameter that is greater than an outer diameter of said ferrule.
13. An optical port adapted to mate with a Versatile Link Family (VLF)-type optical plug and with a non-VLF-type optical plug, the optical port comprising:
a port base; and
at least a first port receptacle, the port receptacle having a proximal end that is attached to the base and a distal end that extends away from the base; the receptacle having an opening therein that extends from the distal end thru the proximal end and into the base, wherein the opening is defined by a receptacle wall having an inner surface and an outer surface, the receptacle having at least one first latching feature and at least one second latching feature, and wherein said at least one first latching feature of the optical port is adapted to engage at least one first latching feature of the VLF-type optical plug when the VLF-type optical plug is mated with the optical port, and wherein said at least one second latching feature is adapted to engage at least one second latching feature of the non-VLF-type optical plug when the non-VLF-type optical plug is mated with the optical port, wherein said at least one first latching feature of the VLF-type optical plug is disposed on at least one outer surface of the VLF-type optical plug, wherein said at least one second latching feature of the non-VLF-type optical plug is disposed on at least one inner surface of the non-VLF-type optical plug, and wherein said at least one first latching feature of the optical port is disposed on an inner surface of the port receptacle, and wherein said at least one second latching feature of the optical port is disposed on an outer surface of the port receptacle.
