distribution box of the building. It is mainly used in integrated buildings, remote medical care, distance education, and large entertainment venues to serve large and medium-sized enterprises and business users, provides high-speed data, e-commerce, visual text and other broadband services. FTTH is to place ONU in the user's home to provide various comprehensive broadband services for home users. FTTH is
used to convert an electrical signal into an optical signal and send it out. It is mainly composed of a light source and a driving circuit. The driver selected in the system design is the MAX3905 optical communication driver chip of Maxim, and its transmission rate is 8 Mbps ~ 150 Mbps. It has two input buffer circuits, one is the input (IN + and IN-) designed for differential data, and the other is the buffer for single-ended input of TTL-level signals. The two are controlled by the DIFF level

Due to the lack of QoS and network security of Users' Services, the IP metropolitan area network is mainly characterized by low cost and good scalability, use L2 switching devices to
Problem description:
When the SSG series firewalls of Juniper can access each other through VPN dial-in or direct mutual access between different network segments, sometimes PING can be reached, but the service cannot be accessed, such as WEB and shared files.
Problem Analysis:
These problems are often c

Because Cable Modem uses a Cable TV network to access the Internet, the information transmission of traditional Cable TV systems is unidirectional, it can only work after converting a one-way CATV Cable TV

Gepon Technology Achievement Advanced Access scheme
With the rapid growth of Internet users, IPTV service and various kinds of network interactive services have put forward more and more requirements for carrying network bandwidth. Optical fiber is the most ideal high bandwidth bearing medium, with the decrease of the cost of optical fiber and related devices, F

Therefore, the emerging operators need to strengthen the construction of pipelines, Rod Road and other basic resources, and the group customers, industrial parks and key areas of the physical resources of the pre-coverage.
