Comprehensive Performance Analysis of various types of Optical Fiber Ethernet Switches

Fiber-optic Ethernet switches are still quite common. So I have studied the comprehensive performance of various types of fiber-optic Ethernet switches. I would like to share with you here and hope they 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 fiber optic Ethernet switch products, but currently there are not many switches with full fiber interfaces on the market. The following describes several full-fiber Ethernet switches.

TP-LINK m all-optical Ethernet switch TL-SF2808C

The intelligent switch TL-SF2808C provides 8 2 km M multimode fiber-optic SC ports with a maximum transmission distance of up. TL-SF2808C support configuration software configuration, support Port VLAN, Port shielding, MAC Address binding and other intelligent configuration. The overall performance of the TL-SF2808C is superior, simple to use, the price is suitable for working group users and Smart Community broadband access to provide an ideal networking solution.

The TL-SF2808C has 8 100 m st Multimode Optical Fiber ports and 1 shared RJ-45 port, supporting 802.3x full duplex flow control and back pressure half duplex Flow Control with, dynamic LED light, provides simple working status prompts and troubleshooting, and provides a terminal (DTE) device to configure the serial port. Supports up to 8 VLAN configurations, static MAC Address binding (up to 18 groups are supported), and MAC address aging time settings. Supports broadcast storm control, which can reduce broadcast storms and split broadcast storms. It provides a terminal device (DTE) configuration serial port, supports Configuration Software settings, full Chinese configuration interface, built-in general power supply, it adopts 19 inch standard steel shell structure design.

OnAccess 1224 S 24 + 2G port Optical Fiber Ethernet Switch

Shenzhen shoumai Communication Technology Co., Ltd. successfully launched an OnAccess System Based on the Ethernet point-to-point network topology with its own intellectual property rights ?. OnAccess is an optical access network based on residential data center exchange. It is an FTTH access technology widely used in North America and Japan with mature technologies and low costs. OnAccess 1224S is a high-performance, 24 + 2G port Fiber Ethernet switch with local network management, replaces the network structure of the fiber optic Ethernet switch and the external photoelectric conversion module, which is commonly used in RJ45 interfaces.

S allows you to flexibly configure the number of 1g uplink photoelectric ports (up to 2) and the number of m downstream optical or electrical ports (up to 24), making the port configuration very easy to expand and upgrade, the downlink port can be selected as a single-mode optical fiber, multi-mode optical fiber, and category-5 access media. It has the function of monitoring the working status of each port photoelectric module by using the network structure of an external photoelectric converter, greatly improve network reliability. It also provides port isolation and port bandwidth control, which is especially suitable for scenarios where the transmission distance exceeds the distance of five types of lines and the need to resist electromagnetic interference. OnAccess is mainly used in residential area Fiber to the home-FTTH broadband access network, enterprise high-speed Fiber local network, high-reliability industrial Distributed Control System (DCS) optical Fiber Digital Video Surveillance Network, hospital high-speed optical fiber LAN, campus network, etc.

Annett AT-8216FXL/SC

Annett's AT-8216FXL/SC is an all-fiber Ethernet switch. For the end-user access of optical fiber, annett abandoned the traditional hub access and introduced the concept of 10 M or 10/100 M switching to users. AT-8126 series switches (10 M/M ports) it creates conditions for flexible access and management.

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.
