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]
The GPON OMCI recommendation G.984.4 draws on G.983.2, which defines the BPON management model. However, G.984.4 removed all references to ATM. G.988 is a stand-alone OMCI recommendation and supersedes G.984.4 except for GPON specifics that are not defined in G.988. Future work on the PON management model is expected to appear only in the GPON ...
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 ...
It is an optical fiber tandem device with many input and output terminals, especially applicable to a passive optical network (EPON, GPON, BPON, FTTX, FTTH etc.) to connect the main distribution frame and the terminal equipment and to branch the optical signal.
Unlike many conventional telephone technologies, this does not provide power for premises equipment, nor is it suitable for direct connection to customer equipment. An optical network terminal (ONT, an ITU-T term), also known as an optical network unit (ONU, an IEEE term), is used to terminate the optical fiber line, demultiplex the signal into ...
Following the publication of 40 Gbps NG-PON2 in July 2015, standardization activities turned to higher speed PON. [4] In November 2016, the Full Service Access Network (FSAN) Group released the Standards Roadmap 2.0 which indicated the development of "future optical access systems" with peak transmission rates above 10 Gbps.
The 6500 Packet-Optical Platform (formerly called the Optical Multiservice Edge 6500 or OME 6500 during the product's time at Nortel) is a multi-port multi-protocol system designed by Ciena that supports TDM/WDM/GigE/10G/40G and 100G ports. [1] [2] It is relevant in the fields of telecommunication, computer networking and optical communications.
