Product introduction
Optical fiber OLT is a device deployed at the operator end (such as a telecommunications bureau). Its function is to transmit Internet signals to users (such as homes, businesses, etc.) through optical fiber lines and receive data uploaded by users.
Product features
Large Capacity
Optical fiber OLT supports a backplane switching capacity of up to 3.2Tbit/s and a control board switching capacity of 1920Gbit/s. This high-capacity design enables OLT to handle data traffic from up to 224 GPON/EPON ports and 672 GE/FE ports simultaneously. Therefore, our equipment is very suitable for parks, communities, buildings, etc. with a large number of users and high bandwidth requirements.
Power Protection
Optical fiber OLT supports dual power protection, that is, the device is equipped with two independent power inputs. When one of the power supplies fails, the other power supply will automatically take over the power supply to ensure continuous operation of the device and avoid network interruption due to a single power failure, thereby improving the stability of the optical fiber system.
Support Multiple Optical Access Methods
Optical fiber OLT is compatible with multiple optical access technologies, including GPON, EPON, XG-PON and point-to-point (P2P) access methods. Various access methods differ in speed, bandwidth and coverage capabilities. An OLT device that supports multiple access methods can be reused in different network scenarios and is not easily eliminated.

Functions of Optical fiber OLT
1. Broadcast Ethernet data to ONUs (Optical Network Units);
2. Initiate and control ranging, and record ranging information;
3. Allocate bandwidth to ONUs, controlling the start time and send window size of ONU data.
Configuration Of Optical Fiber OLT
On the one hand, signals carrying various services are aggregated at the central office and sent to the access network according to a specific signal format for transmission to end users. On the other hand, signals from end users are sent to various service networks based on service type.
It can be divided into three parts:
- Core part: Includes aggregation and distribution, service processing, and ODN adaptation.
- Service part: Provides service interface functions, including interface adaptation and interface protection, as well as service-specific signaling processing and media transmission format conversion when needed.
- Common part: Includes power supply and OAM functions.
