BROADBAND: In the telecommunications field, the phrase Broadband generally indicates the transmission and reception of information at a connection speed higher than 144 kb/s.
ULTRA BROADBAND: We talk about ultra broadband when the actual connection speed for downloading is at least 30 Mb/s. When the connection speed reaches or exceeds Gb/s we speak in general terms about ultrafast networks.
BIT RATE (baud rate): indicates the number of bits transmitted or received over a telecommunications channel within a unit of time. The Bit rate then quantifies how much information can be transmitted and received, per second, in terms of bits or multiples thereof, typically Mbps (Mega) or Gbps (Giga; 1.000 Mbps are equal to 1Gbps). The higher the guaranteed bit rate is, the higher the quality of service provided.
FTT-N: acronym of Fiber To The Node. Indicates an infrastructure in which the optical fiber terminates at an intermediate node of the access network or at a link node to radio carrier access systems.
FTT-DP: acronym of Fiber To The Distribution Point. Indicates an infrastructure in which the optical fiber terminates at an optical termination point (Distribution Point) located 50 metres or less away from the Real Estate Unit (REU);
FTT-B: acronym of Fiber To The Building. Indicates an infrastructure in which the optical fiber terminates at an optical termination point located at the base of the building which houses the Real Estate Unit (REU);
FTT-H: Stands for Fiber To The Home. Indicates an infrastructure in which the optical fiber terminates at an optical termination point inside the Real Estate Unit (REU).
LATENCY: represents the time it takes a bit to travel a certain distance. In general, in telecommunications, it represents the delay between the moment of the request for information and the instant in which the information is received by the user. The lower the latency time, the higher the quality of service provided.
QUALITY OF SERVICE or QoS: Indicates a set of parameters used to characterise the quality of a service offered on a telecommunications network. The main parameters include the bit rate, latency and throughput.
SYMMETRY OF CONNECTION: shows parity of bit rate between download and upload of data and/or information.
THROUGHPUT: Indicates the maximum capacity of information a network can support (static throughput) or manage (dynamic throughput). The latter is dependent on the management potential (control plan). The higher the temperature, the better the service quality.
