SFP Tranceivers Conversion Repeater

Fiber optic transceivers are generally divided into two types, SFP Tranceivers one is the short distance twisted pair electrical signals and long distance optical signals interchangeable Ethernet transmission media conversion unit, commonly known as photoelectric converter; SFP Tranceivers the other is The optical signal into electrical signals, and then converted to another optical signal, SFP Tranceivers also known as fiber conversion repeater. The product is generally used in the actual network environment where the Ethernet cable can not be covered and must be used to extend the transmission distance, and is usually located in the access layer application of the broadband metro network; while helping to connect the last mile of the fiber to the metro Network and more outside the network also played a huge role.

Because we often use the network cable (twisted pair) the maximum transmission distance has great limitations, the general twisted pair of the maximum transmission distance of 100 meters. Therefore, when we are in the layout of the larger network, had to use relay equipment. SFP Tranceivers Of course, you can also use other types of lines to transmit, such as fiber is a good choice. Fiber transmission distance is very far, in general, single-mode fiber transmission distance of 10 km or more, and multi-mode fiber transmission distance can reach a maximum of 2 km. When using fiber, we will often use fiber optic transceivers. Then the problem came, SFP Tranceivers how to use fiber optic transceivers? How does it access the network?

We all know that a network is composed of a variety of optical devices, fiber optic transceivers is one of the important components. In the fiber optic transceivers access network, the first cable from the outdoor introduction. The cable is spliced in the cable box, the terminal box. SFP Tranceivers The welding of the cable is also a door to learn, need to peel the cable, the fiber in the fiber and pigtail welding, welding and then placed in the box. The pigtail is pulled out, connected to the ODF (a shelf, connected by a coupler), SFP Tranceivers connected to the jumper by a coupler, and finally the jumper is connected to the fiber optic transceiver.

There are a wide variety of fiber transceivers on the market today, SFP Tranceivers but in general, there are two types of fiber optic transceivers that are used in connection between copper and fiber optic cables and fiber optic transceivers for fiber and cable connections.

This type of fiber optic transceivers are mainly T1 / E1 and T3 / E3 two models. These two fiber optic transceivers need to be used in pairs, in extending the cable transmission distance, SFP Tranceivers to avoid noise, improve service quality and network security and so can play a role. SFP Tranceivers T1 / E1 fiber optic transceivers meet T1 (1.544Mbps) and E1 (2.048Mbps) standards, for T1 and E1 connection line installation and maintenance, such fiber optic transceivers can also play a test and troubleshooting role. T3 / E3 fiber optic transceivers meet T3 (44.736Mbps) and E3 (34.368Mbps) standards, can be used to connect PBX (private branch exchange, SFP Tranceivers dedicated packet switches), multiplexers and routers and other equipment. This type of fiber optic transceivers can be used for signal transmission between buildings and can expand telecom points.
