An optical line termination (OLT), also called an optical line terminal, is a device which serves as the service provider endpoint of a passive optical network. It provides two main functions: to perform conversion between the electrical signals used by the service provider's equipment and the fiber optic signals used by the passive optical ...
A passive optical network consists of an optical line terminal (OLT) at the service provider's central office (hub), passive (non-power-consuming) optical splitters, and a number of optical network units (ONUs) or optical network terminals (ONTs), which are near end users. [2] [3] There may be amplifiers between the OLT and the ONUs. [4]
An optical network terminal mounted to the outside of a building, with the cover open. In fiber-to-the-premises systems, the signal is transmitted to the customer premises using optical fiber technologies. Unlike many conventional telephone technologies, this does not provide power for premises equipment, nor is it suitable for direct ...
The bandwidth of the single connection between the OLT (optical line termination) and the ONTs (optical network terminals) is 2.4 Gbit/s down, 1.2 Gbit/s up, or rarely symmetric 2.4 Gbit/s, [1] shared between up to 128 ONTs using a time-division multiple access (TDMA) protocol, which the standard defines. [4]
The OLT (optical line terminal) connects the PON to aggregated backhaul uplinks, allocates time slots for ONUs and ONTs to transmit upstream data, and transmits shared downstream data in broadcast-mode over the PON to users. Since 10GPON is designed to coexist with GPON devices, migration to a 10GPON capability could be done by upgrading the ...
An access network, also referred to as an outside plant, refers to the series of wires, cables and equipment lying between a consumer/business telephone termination point (the point at which a telephone connection reaches the customer) and the local telephone exchange. The local exchange contains banks of automated switching equipment which ...
A given headend may have between 1–12 CMTSs to service the cable modem population served by that headend or HFC hub. One way to think of a CMTS is to imagine a router with Ethernet interfaces (connections) on one side and coaxial cable RF interfaces on the other side. The Ethernet side is known as the Network Side Interface or NSI. [3] [4]
OTN multiplexing and mapping structures. Show the relationship between ODU Clients, ODU, ODU-Groups and OTU. OTN was designed to provide higher throughput (currently 400G) than its predecessor SONET/SDH, which stops at 40 Gbit/s, per channel.
