DETAILED DESCRIPTION

Various examples will be described in detail with reference to the drawings, wherein like reference numerals represent like parts and assemblies throughout the several views. Reference to various examples does not limit the scope of the claims attached hereto. Additionally, any examples set forth in this specification are not intended to be limiting and merely set forth some of the many possible examples for the appended claims. Referring to the drawings wherein like reference numbers correspond to like or similar components throughout the several figures.
Referring to FIG. 1, a smart pole assembly 10 is shown. In one aspect, the smart pole assembly 10 can include a pole structure 12 having a hollow interior supported by a base 14. A lamp or light fixture 16 can be supported by the pole structure 12 and can be powered by a power line 20 extending through the base 14 and pole structure 12.
The smart pole assembly 10 can also be provided with a communications module 18 supported by the pole structure 12. The data-communications module 18, which can be provided with an enclosure 19, can be provided to support and/or house a variety of data-communications equipment components 30. For example, the data-communications module 18 can be provided with a metro cell mobile phone station 30 a including one or more radio heads and antennas, a wireless transceiver 30 b, a photo-cell for sensing ambient light conditions, speakers, microphones, cameras, RFID sensors, a back-up battery system, and/or photovoltaic systems. Some examples are shown at FIG. 3. U.S. Pat. No. 9,106,981 entitled Aggregation enclosure for elevated outdoor conditions and issued on Aug. 11, 2015, also includes examples of data-communications components and systems, the entirety of which is incorporated by reference herein. Many other possibilities exist, depending upon the desired application and location of a particular smart pole assembly 10.
Due to the wide variety and combinations of potential components that could be associated with the data-communications module 18, it is desirable to have a system which is adaptable such that a plug and play environment exists for connections between the components and the cabling within the pole structure 12. Such flexibility allows for components to be easily installed onto a pole without requiring a new run of cable through the entire pole structure 12. Also, such an arrangement avoids needing to remove existing cabling associated with a removed component through the pole structure 12. The disclosed system is flexible in all of the aforementioned ways. To this end, and as shown at FIGS. 2 3, the data-communications module 18 may be provided with quick-disconnect jumper cabling 32 for connection with the components associated with the data-communications assembly 18. For example, a fan-out harness 32 a can be provided with multiple ruggedized or hardened connectors, for example multiple hardened multi-fiber optical connectors (FDVIFOC) can be provided for connection with the adapters of multiple components 30. An example of an FDVIFOC-type connection is shown and described in U.S. Pat. No. 9,348,096 entitled Passive Distribution System using Fiber Indexing and issued on May 24, 2016, the entirety of which is incorporated herein by reference. One or more Category 6 (CAT6) power over Ethernet (POE) jumper cables 32 b can also be provided. AC and/or DC power jumper cabling 32 c can also be provided for powering the components 30.
Referring to FIGS. 2 and 4, the jumper cabling 32 can be connected to vertical connectivity cabling structures or harnesses 50 which are routed through the pole structure 12. For example, a cable 50 a can be provided with fiber optic cables with hardened multi-fiber optical connectors (HMFOC) at each end. As such, the cabling structures 50 can be characterized as being connectorized at both ends. One or more Category 6 (Cat 6) power over Ethernet (POE) cables 50 b can also be provided, for example a cable including a plurality of copper-based twisted-pair cables. AC and/or DC power cabling 50 c can also be provided. In the particular example shown at FIG. 4, a 12 fiber HMFOC cable 50 a, two CAT6 cables, and three DC power cables 50 c are provided and routed through the pole structure 12 and connected to the associated jumper cables 32. With such a configuration, the cabling structures 50 can remain in place when components 30 are added, removed, and/or replaced since the required jumper cables 32 can be likewise added, removed, and/or replaced instead of the entire cabling run from the base 14 to the data-communications module. However, it should be understood that cabling can be added, removed, and/or replaced within the hollow interior of the pole structure 12 at any time, if desired.
In one aspect, the data-communications module 18 or the pole structure 12 can include an organized connectivity box 34, panel, or enclosure receiving the jumper cabling 32 and the vertical cabling structures 50 such that they can be interconnected. Where the jumper cabling 32 and vertical cabling structures 50 include optical fibers, the organized connectivity box 34 can include an adapter arrangement including one or more adapters into which the connectorized optical fibers of the jumper cabling 32 and vertical cabling structures 50 can be received. The organized connectivity box 34 can also include strain relief features such that the weight of the vertical cabling structures 50 does not exert stress onto the connections with the jumper cabling 32.
Referring to FIGS. 5-5B, the base 14 can be additionally provided with base connectivity cabling and equipment 70 for connection with the connectivity structures 50. In the example shown at FIG. 5, a HMFOC fiber splice cable 70 a, a splice closure 70 b, and power supply cabling 70 c are provided. In the example shown at FIG. 5 A, HMFOC fanout cabling 70 d, a demarcation box 70 e, and power supply cabling 70 c are provided. In the example shown at FIG. 5B, a HMFOC hardened fanout 70 f, a hardened pretermination box 70 g, and power supply cabling 70 c are provided. The modularity of the base cabling and equipment 70 allows for the cabling and equipment 70 a-70 g to be easily installed, removed, and/or replaced without requiring replacement of the vertical cabling structures 50.
In some examples, the splice closure 70 b, demarcation box 70 e, and/or the hardened pretermination box can be housed in a separate substructure from the base 14, such as a vault or a stand-alone enclosure, and can function as a fiber backhaul 90, as shown in FIG. 6. In such a configuration, the power cabling 70 c can also be fed through the substructure that houses the fiber back-haul 90. In one example, the substructure can also include a battery back-up for providing power to the connected light pole assemblies 10.
Referring to FIG. 7, a schematic representation of a first topology arrangement 100 utilizing a plurality of smart pole assemblies 10 is presented. In this configuration, the smart pole assemblies 10 are installed with traditional street light wiring 102 where AC power is fed and controlled from a central point. One or more of the smart pole assemblies 10 are each provided with a vertical connectivity cabling structure 50 such that the smart pole assemblies 10 are ready for installation of any desired data-communications equipment 30 at a later time.
Referring to FIG. 8, a schematic representation of a second topology arrangement 200 utilizing a plurality of smart pole assemblies 10 is presented. In this configuration, a master smart pole assembly 10A is installed along with one or more standard smart pole assemblies 10B. Each of the smart pole assemblies 10 (i.e. 10A and 10B) is configured with traditional street light wiring 202 where AC power is fed and controlled from a central point. The master smart pole assembly 10A is provided with metro cell equipment 30A equipment and a fiber fanout or splitter 32A inside or adjacent. Each smart pole assembly 10B also has a vertical connectivity cabling structure 50 inside the pole 12 making the poles 10B “smart” ready. Thus in the future, the incumbent only needs to work on the top of the pole 12 and the fanout or splitter 32A at the master pole 10A to provide connectivity between the smart pole assemblies 10A, 10B. This work can be accomplished by a single installer which is an advantage over poles of the type where cabling must be entirely installed, removed, and/or replaced through the pole structure 12 which generally requires two installers with a fish tape. The exact count of vertical fibers within the vertical connectivity cabling structure 50 can be provided to handle a predetermined number of connections. For example, the vertical connectivity cabling structures 50 can be provided with at least twelve fibers per cable. Twenty four fibers per cable is also possible.
Referring to FIG. 9, a schematic representation of a third topology arrangement 300 utilizing a plurality of smart pole assemblies 10 is presented. Similarly to the arrangement shown at FIG. 8, the third topology arrangement 300 includes a master smart pole assembly 10A is installed along with one or more standard smart pole assemblies 10B. However, the third topology arrangement 300 additionally includes an AC to DC power converter or rectifier 92 at the fiber backhaul 90 that is connected to the AC power feed 302. The rectifier 92 is connected to the backhaul 90 which then feeds DC power to each smart pole assembly 10A, 10B via power supply cabling 70 c. Power supply cabling 70 c is connected to power supply cabling 50 c and power jumper cabling 32 c, as described above. The current power feed from the rectifier 92 can be 48VDC, power over ethernet (POE) power, or both. In one example, the master smart pole assembly 10A can house the backhaul fiber splitters and power unit/rectifier 92 inside or adjacent to the master pole, for example within the base 14. These components could also be remotely located, such as in a vault or separate enclosure. The power rectifier 92 can also include provisions for a backup power source (like batteries).
