Comprehensive Analysis of Ethernet switch access solutions

Ethernet switches are still commonly used. So I studied the Ethernet switch access solution and shared it with you here. I hope it will be useful to you. Fiber-optic Ethernet technology is the integration and development of the two mainstream communication technologies, namely, 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 the bandwidth bottleneck between the LAN and WAN, and will become a single network structure integrating voice, data and video in the future.

The Optical Fiber Ethernet product can use Ethernet devices to implement WAN communication services in the format of Ethernet data 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 introduced fiber-optic Ethernet switches. These switches 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 switch is connected to an Internet edge router or collection switch at a rate of 1000 Mbit/s, connect a residential network to the Internet. The optical fiber switch uses optical fiber and point-to-point mode to connect a m duplex to an optical network unit or a built-in optical fiber Ethernet card in the user's home. This enables users to access the Internet through optical fiber at a high speed. The link between an optical switch and an optical network unit is the 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.

Introduction to Optical Fiber Ethernet Switches

Because Fiber Optic Ethernet switches can provide high-speed and low-cost fiber access solutions, many manufacturers have released their own Ethernet switches with fiber interfaces. However, there are not many switches with fiber interfaces on the market. The following describes several full-fiber Ethernet switches.

Summary:

According to the general development trend, the application of optical fiber in the access network should first Replace the feeder fiber with the feeder fiber, and then continue to advance to the user. However, the cost is getting higher and higher, therefore, the optical fiber is usually only used to distribute data to the roadside, that is, the Business Access Point (SAP ). The ultimate goal of the pure optical fiber access network is to promote the fiber to residential users. It is not realistic to get the fiber to the home because the price of the fiber is too expensive. Therefore, fiber-optic Ethernet access is a low-cost FTTH solution.
