The following pages contain a number of architectural designs that can be applied to a broadband network. The application of the SPSM in a network is limited
only by the creativity of the designer.
Optional Design Methods Using SPSP Power

The following example shows the addition of a new power supply at the remote location to backup the local power supply. The existing
coaxial cable is being used to transfer power from remote location to local power supply.

The following example shows a typical dual backup SPSM design. If the power supply fails at either location it is backup from the
other location.

The following example uses the trunk a/c port for powering at one location and multiple power insertion locations at the second. A
standard power inserter is used to properly distribute power to the network.

The following example shows how power feeder or coaxial cable is used to supply power between optical nodes. After a system
upgrade there may be spare conduits or coaxial cable that can be used to power the network.

In the following example two remote power supplies are used to backup the middle power supply. A high current load or long
distance between power supplies prevent create high current draws. Another solution is to split the local powering into two sections, then backup
each section from a different location.

In the following example there are trunk amplifiers between power supply locations. In this case one of the power supplies will be used to
power the trunk amplifiers between the power supplies.

In the following example power feeder has been placed between the power supplies locations to provide a more efficient power scheme. This design
also eliminates the amplifiers in the coaxial RF cable from impacting power loading as power fails and is restored.

The following example is of a triple backup design using coaxial or power feeder cable between the nodes. Any two adjacent power supplies can
fail and the remaining PS will feed the network.
