Abstract

The invention discloses a regenerating optical network of a gigabit Ethernet passive optical network and a gigabit Ethernet optical network system. The regenerating optical network comprises a wavelength division multiplexer, an optical-electrical conversion unit and an electrical-optical conversion unit. The wavelength division multiplexer is used for receiving optical signals, demultiplexing the optical signals and transmitting the signals to the optical-electrical conversion unit, the optical-electrical conversion unit is used for optical-electrical signal conversion of the received optical signals, processing electrical signals obtained during conversion, and transmitting the electrical signals to the electrical-optical conversion unit, and the electrical-optical conversion unit is used for regenerating optical signals through the received electrical signals, and the optical signals are multiplexed by the wavelength division multiplexer and transmitted to a receiving terminal. Although the regenerating optical network of the gigabit Ethernet passive optical network is not used as an active device, the transmission of large splitting ratio and ultra-long distance can be achieved through the gigabit Ethernet passive optical network; the cost is lower; and the implementation is more flexible, difficulties in operation are greatly reduced, and the product reliability is effectively improved.

Description

Technical field [0001] The present invention relates to the technical field of optical communication, in particular to a 10 Gigabit Ethernet passive optical network regeneration optical module. Background technique [0002] With the increasing demand for high-bandwidth services such as high-definition IPTV and video surveillance, the industry has gradually realized that the existing EPON and GPON access network technologies are difficult to meet the needs of long-term business development, especially in the fiber to the building ( FTTB) and fiber to the node (FTTN) scenarios. Optical access networks are facing new upgrade requirements in terms of bandwidth, service support capabilities, and access node equipment functions and performance. According to analysis, the per capita bandwidth demand of each family member will increase from 30Mbps to 125Mbps. At present, the transmission rates of GEPON and GPON technologies with 32-channel topology can reach 1.25Gbps and 2.5Gbps respec...
