All solutions for fiber optic Ethernet switch access

The Application of Fiber-Optic Ethernet switches is becoming more and more extensive. Here we mainly introduce the ACCESS scheme of fiber-optic Ethernet switches and its practical application problems. The fiber-optic Ethernet technology is the integration and development of the two mainstream communication technologies, that is, Ethernet and optical network. It integrates the advantages of Ethernet and optical networks, such as common Ethernet applications, low costs, flexible networking, simple management, high optical network reliability, and large capacity. The high-speed and high-capacity optical Ethernet eliminates bandwidth bottlenecks between LAN and WAN.

It will become a single network structure for integrating voice, data, and video in the future. Optical Fiber Ethernet switches can use Ethernet devices to implement WAN communication services in the format of Ethernet packets. Currently, optical fiber Ethernet can achieve 10 Mbps, Mbps, 1 Gbps, and other standard Ethernet speeds.

An Optical Fiber Ethernet device is based on a layer-4 LAN switch, a layer-2 LAN switch, a SONET device, and a DWDM device. Some companies have launched fiber-optic Ethernet switches, which have multiple features and can ensure service quality as much as possible (such as packet classification and congestion management ). Such products may require the following key technologies and Performance: high reliability, high port density, service quality assurance, and other functions.

Fiber-optic Ethernet is more cost-effective than other broadband access services, but so far it is only used in office buildings or buildings where fiber-optic cables are already deployed. The strategic value of this new method using Ethernet is not limited to cheap access. It can be used for both access networks and local backbone networks in the service supplier network. It can be used only at Layer 2nd or as an effective way to implement layer 3rd businesses. It supports IP, IPX, and other traditional protocols. In addition, because it is still a LAN in nature, it can be used to help service providers manage the enterprise LAN and the interconnection between the enterprise LAN and other networks.

Access Solution for Optical Fiber Ethernet Switches

The core network device is an optical fiber switch placed in a residential data center or building data center. The optical fiber Ethernet switch is connected to an Internet edge router or a collection of Optical Fiber Ethernet switches at a rate of 1000 Mbit/s, connect a residential network to the Internet. An Optical Fiber Ethernet switch connects a m duplex to an optical network unit or a built-in optical fiber Ethernet card at a point-to-point rate, enabling users to access the Internet through optical fiber at a high speed. The link between an optical fiber Ethernet switch and an optical network unit is a single-fiber Bidirectional mode.

Compared with the existing LAN broadband access method based on five types of lines, this access scheme has the following outstanding features: it is a low-cost FTTH solution; it saves floor switches, and only the residential data center is an active node, reduces maintenance costs; a single switch node in the residential data center effectively improves the utilization of switch ports; ultra-high bandwidth, 100 times that of ADSL; far access distance; remote network monitoring of each port photoelectric module; provides port isolation and port bandwidth control functions, and powerful Web Server network management functions. This solution is especially suitable for ordinary residential users, office buildings, schools, hospitals, and other carriers. It is suitable for traditional telecom operators and resident network operators.
