Fiber transceiver basic connection:
Fiber-optic transceivers are Ethernet transmission media conversion units that exchange short-distance twisted-pair electrical signals with long-distance optical signals and are also referred to as optical-to-electrical converters in many places. Products are typically used in Ethernet. Cable cannot cover, must use the optic fibre to prolong the transmission distance in the actual network environment, and usually locate in the access layer application of the broadband metropolitan area network.
The medium that plays a role in the traditional Ethernet connection is mainly twisted pair. The transmission distance of the twisted pair is approximately 100 meters. Such a short transmission distance restricts the development of the network, and the twisted pair is affected by the electromagnetic interference. Larger, this will undoubtedly greatly affect the quality of data communications. The use of fiber optic transceivers will change the connection medium in Ethernet to fiber optics. The fiber's low loss, high electromagnetic interference immunity, make the network transmission distance from The 100-meter extension to 2 or even several tens of kilometers, as well as hundreds of kilometers, has also greatly improved the quality of data communications. He has made the interconnection between servers, repeaters, hubs, terminals and terminals even more Simple.

In practical applications, fiber optic transceivers basically have the following three basic connection methods:
1. Circular Backbone Circular Backbone Network is the use of SPANNING TREE features to build a backbone within the metropolitan area. This structure can be transformed into a mesh structure, suitable for high density of the central area of ​​the metropolitan area network, forming a fault-tolerant core backbone network. Backbone network support for IEEE.1Q and ISL network features can be guaranteed to be compatible with most mainstream backbone networks, such as cross-switch VLANs, trunks, and other functions. The ring backbone network can establish broadband virtual networks for financial, government, and education industries. Private Network.
Second, the chain backbone Backbone backbone of the use of chain-shaped connection can save a large number of backbone light, suitable for the construction of high-bandwidth low-cost backbone network in the city's edge and its suburbs and counties, this model can also be used at high speed Environments such as highways, oil transmission lines, and transmission lines. The support of IEEE 802.1Q and ISL network characteristics in a chained backbone network can be guaranteed to be compatible with most backbone networks. It can establish broadband virtual private networks for finance, government, education and other industries. The chain backbone network is a multimedia network that can provide comprehensive transmission of images, voice, data, and real-time monitoring. Third, the user access system user access system can use 10Mbps/100Mbps auto-adaptation and 10Mbps/100Mbps auto-conversion function to connect any Client-side equipment, without the need to prepare a variety of fiber transceivers, can provide a smooth upgrade scheme for the network. At the same time, the use of half-duplex / full-duplex adaptive and half-duplex / full-duplex automatic conversion function, can be configured at the user side cheap The half-duplex HUB reduces the networking cost of the client by several times and improves the competitiveness of the network operator. Meanwhile, the built-in switching core of the device improves the access device. Transmission efficiency, reduce network broadcast, control traffic, detecting transport failure.
