OLT is the abbreviation of Optical Line Terminal, which is translated into Chinese as optical line terminal. It is one of the key equipment used in the optical fiber communication system called optical distributed switching network (PON). An OLT is typically a device located at a switching center or central site of a fiber optic network provider such as a telecommunications company.
OLT Function:
OLT is responsible for managing and controlling the entire optical distributed switching network (PON).
It transmits data from the central site to the optical network terminal (ONT) or optical network unit (ONU) at the user end, and vice versa.
OLT is usually responsible for functions such as data forwarding, routing, scheduling, and monitoring to ensure efficient operation of the network.
OLT connect:
The OLT is connected to the optical fiber distributor (ODN) through optical fiber to send data to the user end.
An optical fiber distributor is a type of optical fiber distribution equipment used to connect a single optical fiber to multiple ONTs or ONUs.
OLT ports:
OLTs typically have multiple fiber optic ports, each of which can be connected to a fiber optic distributor to support multiple users.
Each fiber port can be connected to hundreds of ONTs or ONUs.
OLT technical standard:
OLT usually complies with standards such as GPON (Gigabit Passive Optical Network) or EPON (Ethernet Passive Optical Network), which stipulate the transmission method and protocol of data in optical fiber communication systems.
Management and monitoring:
OLT has management and monitoring functions that can remotely monitor and manage network status, device connections, and performance indicators.
These capabilities enable operators to perform troubleshooting, resource planning and network optimization.
In general, OLT is the core device in the optical distributed switching network (PON). It is responsible for managing and controlling the optical fiber communication system, transmitting data from the central site to the user terminal, and providing management, monitoring and scheduling functions to ensure that the network efficient operation.
