The simplest optical distribution network architecture is direct fiber: each fiber leaving the central office goes to exactly one customer. These networks can support a lot of bandwidth, but they cost more because of the fiber and the equipment in the central office. [33] Direct fiber is generally favored by new entrants and competitive operators.
Network planning and design is an iterative process, encompassing topological design, network-synthesis, and network-realization, and is aimed at ensuring that a new telecommunications network or service meets the needs of the subscriber and operator. [1] The process can be tailored according to each new network or service. [2]
Design–build (or design/build, and abbreviated D–B or D/B accordingly), also known as alternative delivery, [1] is a project delivery system used in the construction industry. It is a method to deliver a project in which the design and construction services are contracted by a single entity known as the design–builder or design–build ...
Distribution networks are divided into two types, radial or network. [10] A radial system is arranged like a tree where each customer has one source of supply. A network system has multiple sources of supply operating in parallel. Spot networks are used for concentrated loads. Radial systems are commonly used in rural or suburban areas.
Serving Area Interface. In telecommunications, the term outside plant has the following meanings: . In civilian telecommunications, outside plant refers to all of the physical cabling and supporting infrastructure (such as conduit, cabinets, tower or poles), and any associated hardware (such as repeaters) located between a demarcation point in a switching facility and a demarcation point in ...
The MDF is a termination point within the local telephone exchange where exchange equipment and terminations of local loops are connected by jumper wires at the MDF. All cable copper pairs supplying services through user telephone lines are terminated at the MDF and distributed through the MDF to equipment within the local exchange e.g. repeaters and DSLAM.
In telecommunications, the term inside plant has the following meanings: . All the cabling and equipment installed in a telecommunications facility, including the main distribution frame (MDF) and all the equipment extending inward therefrom, such as PABX or central office equipment, MDF heat coil protectors, and grounding systems.
NIS may manage all data relevant to the network, e.g.- all components and their attributes, the connectivity between them and other information, relating to the operation, design and construction of such networks. NIS for electricity may manage any, some or all voltage levels- Extra High, High, Medium and low voltage.
