14. The communications pedestal of claim 10 further comprising a signal splitter positioned in the cavity of the body portion of the stubbed terminal housing.

15. The communications pedestal of claim 10 wherein the plurality of fiber optic ports include a fiber optic cable entry port and an array of fiber optic fiber exit ports extending perpendicularly from a lower surface of the body portion.

16. A communications vault comprising: a plurality of substantially vertical sidewalls; a stubbed terminal housing for fiber optic cable management in the utility vault having a body portion, a cavity within the body portion, a plurality of fiber optic fiber ports extending from the body portion for entry and exiting of fiber optic fibers, and a mounting portion extending from the body portion for attaching the stubbed terminal housing to the utility vault.

17. The communications vault of claim 16 wherein the mounting portion attaches to a substantially vertical wall of the communications vault by a fastener engaging a bracket positioned on the substantially vertical wall and received within a bore in the mounting position.

18. The communications vault of claim 16 wherein the mounting portion attaches to a substantially vertical wall of the communications vault by a fastener extending through the substantially vertical wall and received within a bore in the mounting portion.

19. The communications vault of claim 16 further comprising a signal splitter positioned within the cavity of the body portion of the stubbed terminal housing.

20. The communications vault of claim 16 wherein the plurality of fiber optic ports include a fiber optic cable entry port and an array of fiber optic fiber exit ports extending perpendicularly from a lower surface of the body portion.

DETAILED DESCRIPTION

[0012] As shown in FIGS. 1 through 3 the present invention is directed to a stubbed terminal housing 10 for use in a grade level communications vault 12 and/or pedestal housing assembly 14 as illustrated in FIGS. 4 and 5. The stubbed terminal housing includes a main body portion 16 and an attachment portion 18. The main body portion includes a domed upper surface 20 and a substantially flat lower surface 22 having a main fiber optic cable port 24 extending perpendicularly downward therefrom and an array of secondary fiber optic fiber ports 26 also extending perpendicularly downward therefrom. As illustrated in FIG. 2, there is an array of 12 secondary fiber ports, however this number can vary depending upon the particular application. The housing typically is made of plastic which can be molded although other materials and manufacturing processes can be utilized.

[0013] The attachment portion 18 includes a cavity 28 formed by an opening in its lower surface 30 so that the housing can be mounted on top of a pedestal stake 32 as shown in FIG. 3. Attachment portion 18 also includes a fastener bore 34 formed along its upper surface 36 for receipt of a mechanical fastener 38 for attachment applications discussed subsequently herein.

[0014] The main body portion 16 is hollow in that the bottom section 22 attaches to the domed section 20 to provide a hollow interior cavity 40 in which a signal splitter 42 can be positioned wherein the fiber optic cable 44 that enters into the housing through main fiber optic cable port 24 attaches and individual fiber optic fibers 46 extend off the splitter and exit the cavity 40 through secondary fiber optic fiber ports 26. For the example illustrated in FIG. 3, the splitter 42 is 1×12 splitter thereby splitting the signal carried by cable 44 into twelve signals through each of individual fibers 46. In other applications no splitter is contained within the cavity of the housing but the cavity serves as the location to fan out the individual optic fibers 46 from cable 44 for the particular communications application.

[0015] Referring to FIGS. 4 and 5 the stubbed terminal housing 10 can be positioned on a pedestal stake 32 within the pedestal housing 14 with a slip fit by positioning the attachment portion 18 on an end of the terminal housing. Alternatively, if the pedestal stake is damaged or otherwise not available for mounting, the housing can be attached by fastener 38 to a bracket 50 or directly to a pedestal faceplate 52. As shown in FIG. 5 when the stubbed terminal housing 10 is used in the grade level vault 12 the threaded fastener 38 can be used to mount the housing to a bracket 54 or directly to a wall 56 of the vault. By incorporating the stubbed terminal housing for transitioning a fiber optic cable into individual fibers it provides the ideal layout and allows the grade level vaults and pedestal housings to be smaller and more compact.

[0016] Although the present invention has been described and illustrated with respect to an embodiment thereof, it is to be understand that changes and modifications can be made therein which are within the full intended scope of the invention as hereinafter claimed. For example, the cable inlet port, although illustrated as circular, can be oval or slotted in shape to accommodate other forms of fiber optic cables, such as ribbon cables. Similarly, the fiber optic fiber outlet ports can be positioned on another surface of the housing depending upon the particular application to efficiently utilize the space provided in the pedestal or communications vault.
