Shenzhen Toplink Technology Co.,Ltd.

OLT equipment is an important central office equipment, which can be connected to the front-end switch with a network cable to convert it into an optical signal,and use a single optical fiber to interconnect with the optical splitter at the user end;realize the control, management, and distance measurement of the ONU of the user end equipment;and the ONU The same as the equipment, it is an integrated photoelectric equipment.

EPON (Ethernet-based Passive Optical Network) is a type of PON network. It is a comprehensive access technology widely used to meet the needs of high-speed broadband services such as video and data with the development of telecommunications technology. The EPON network consists of three parts: OLT, ODN and ONU. The main features are point-to-multipoint, passive lines, simple and clear network levels, and the ability to provide comprehensive access to multiple services such as voice, broadband, and CATV.

The GPON standard is the ITU-T G.984 series. It follows the APON standard protocol framework and adds GEM, a new TC layer frame encapsulation method. It has strict regulations on QoS and OAM, and has a strong ability to carry TDM services. Relatively complicated. GPON has a high transmission rate and a large split ratio, which can provide TDM services with high timing accuracy.
