gigabit passive optical network

The optical fiber access network is worth learning a lot. Here we mainly introduce the current situation and development trend of the access network in China's communication industry, including the TMN status of the access network and the remote network management technology

technical uncertainties, coupled with cost factors, more importantly, there is a lack of practical application markets, so these plans are put on hold. The rise of Internet and interactive video communication and the decline in the price of optical fiber and optical devices have laid a solid foundation for the development of optical fiber access networks from bo

network application types and have higher requirements on network bandwidth, transmission quality, and network performance. Network applications must integrate advanced, multi-service, scalability, and stability to meet customers' needs for simultaneous transmission of voice, video, and data over a broadband

area network. OAN enables service providers to submit fiber-based broadband services to enterprises of all sizes. OAN based on passive optical network, PON) does not need to install expensive active electronic devices on the external site, so that service providers can provide enterprises with the required bandwidth i

changing the system backplane, the main control circuit board and time slot intersection board, and the Group of light cards and the branch light card is the same board card. Even under the 10Gbps system configuration, can still up and down E1 circuit. At the same time, 2.5G and 10G optical interface cards can be configured into DWDM prefabricated optical mouth, which is very convenient to improve the syst

transmission layer shows the development trend of all-optical networks. From the ASON technology on the core layer to the FTTP technology on the access layer, there is no indication that the evolution of network bearer to light; in addition, service integration is based on IP addresses. The development of Internet makes IP addresses the most ideal service bearer protocol, MSTP, RPR, MPLS, and other technol
