Description: A FiberInterconnect terminates individual fibers or establishes a connection between two or more fiber cables. Fibers in cables are connected to signal ports in the equipment. Ports are not shown graphically within ArcGIS; therefore these are modeled using a relationship to the FICPort Object (database only features).
Description: A Multiplexer (MUX) is a device that combines multiple inputs into an aggregate signal to be transported via a single transmission channel. Fibers in cables are connected to signal ports in this equipment. Ports are not shown graphically within ArcGIS, therefore these are modeled using a relationship to the MUXPort Object (database only features).
Description: A Patch Panel is device where connections are made between incoming and outgoing fibers. Fibers in cables are connected to signal ports in this equipment. Ports are not shown graphically within ArcGIS; therefore these are modeled using a relationship to the PatchPanelPort Object (database only features).
Description: A Splitter is a transmission coupling device for separately sampling (through a known coupling loss) either the forward (incident) or the backward (reflected) wave in a transmission line. Fibers in cables are connected to signal ports in this equipment. Ports are not shown graphically within ArcGIS; therefore these are modeled using a relationship to the SplitterPort Object (database only features).
Description: A usually weatherproof encasement, commonly made of tough plastic, that envelops the exposed area between spliced cables, i.e., where the jackets have been removed to expose the individual transmission media, optical or metallic, to be joined. The closure usually contains some device or means to maintain continuity of the tensile strength members of the cables involved, and also may maintain electrical continuity of metallic armor, and/or provide external connectivity to such armor for electrical grounding. In the case of fiber optic cables, it also contains a splice organizer to facilitate the splicing process and protect the exposed fibers from mechanical damage. In addition to the seals at its seams and points of cable entry, the splice closure may be filled with an encapsulate to further retard the entry of water.
Description: A Riser is a cylindrical or channel enclosure attached to a pole or structure to provide protection for underground conduit as it transitions from overhead to underground.
Description: Poles are point objects that support telecom devices and cables. Although many telecom systems are now being built, a tremendous amount of overhead plant is still in use. Overhead poles are subject to vertical and horizontal forces including weight of cables and other equipment. Vertical forces are the unbalanced component of wire tension at curves and corners, the pull of service drops, and the horizontal component of weight if the pole is not vertical. Wood poles have long been used for overhead distribution because of abundance of material, ease of handling and cost. The strength of a wood pole must be sufficient to withstand abnormal loads as well, such as ice and wind pressure. Pole features can have street lights, assemblies, and other attachments associated with them.
Description: Structure is a concrete feature class that describes features needed to support an underground telecommunications system. It is a simple junction feature that includes vaults, manholes, that house and protect electrical equipment. Structures are underground access point for cable and splices. It is comprised of the following types: Manhole, Handhole, Pullbox, and Vault.
Description: A Fiber Optic Cable is composed of thin filaments of glass through which light beams are transmitted to carry large amounts of data. The optical fibers are surrounded by buffers, strength members, and jackets for protection, stiffness, and strength. A fiber-optic cable may be an all-fiber cable, or contain both optical fibers and metallic conductors.
