Aerial Installation
POAs and PLAs
What does it all mean? POAs and PLAs?
In the field of electrical engineering, POA is an acronym for Point-of-Attachment, which refers to the specific location where a service drop connects to a building. This connection point is of critical importance as it is the point where the electrical service enters the building. PLA, on the other hand, stands for Pole Loading Analysis, which is a process used to determine the maximum amount of weight that a utility pole can safely support. This analysis is essential in ensuring that the utility pole remains structurally sound and does not pose a safety hazard to the surrounding area.
When it comes to deploying fiber, there are two main options: aerial installation and fiber in a duct solutions. Aerial installation involves deploying fiber above ground on poles or towers, which eliminates the need for underground digging. This option is particularly useful when the ground is uneven, rocky, or both. Additionally, aerial installation is generally much less costly than underground construction. However, it's worth noting that aerial installations can be affected by adverse weather conditions such as high winds freezing rain. On the other hand, fiber in a duct solutions offer a major aesthetic advantage. Once installed, they are invisible and leave no mark on the landscape. This makes them an ideal option for areas where preserving the natural beauty of the surroundings is a priority. However, it's important to keep in mind that underground installations can be vulnerable to flooding damage. Overall, both aerial cable installation and fiber in a duct solutions have their advantages and disadvantages. The best option for your project will depend on a variety of factors, including the terrain, budget, and aesthetic considerations.

Aerial installation can be a highly advantageous solution for challenging terrain, as it is faster and more cost-effective to deploy than buried networks. Additionally, the use of All-Dielectric Self Supporting (ADSS) cables can enable pole sharing and reduce installation costs when erected in close proximity to power transmission lines.
In order to ensure a successful aerial installation, it is of
paramount importance to carry out a meticulous and comprehensive
design of the cable plant, followed by a thorough check. This process involves conducting a detailed survey of the routes, testing the ground conditions, procuring all the necessary components, obtaining the required permits from the local authorities, and meticulously coordinating with local agencies, such as traffic and police departments. In the event poles already exist, it is mandatory to obtain the appropriate permits for adding communications cables, and the poles must be "made ready" by the owner of poles or
authorized parties. It is worth noting that this may
take a considerable amount of time, which must be
taken into account when planning the project.
In some cases, lightweight fiber cable may be lashed
to previously installed cables, such as older copper
phone cables or CATV hardline coax, but it is crucial
to obtain the proper permissions beforehand. Prior to
installation, it is also essential to determine the
location of splice points and storage of slack cables,
and to note these details in the design. It is advisable
to choose splice locations that allow for parking a
splice truck, van, or trainer nearby, as this will facilitate
the installation process.
