SFP Tranceivers The Role

SFP Tranceivers Fiber optic transceivers are generally divided into two types, 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, also known as fiber conversion repeater. SFP Tranceivers 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 a larger network, had to use relay equipment. 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, SFP Tranceivers 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, 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, SFP Tranceivers the first cable from the outdoor introduction. The cable is to be welded in the cable box, that is, the terminal box. 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. Followed by the order of the order of the router ---- switch --- LAN --- host. In this way, the fiber optic transceivers access the network.

The biggest feature of the WDM Optical Amplifier Repeater Series (OEO) is the ability to receive, amplify, and re-transmit signals at different wavelengths without changing the data / signal content. Today, wavelength conversion can only be achieved through the WDM optical repeater series (OEO). SFP Tranceivers The WDM optical repeater series (OEO) operates as a regenerator, converts the optical input signal into an electrical signal, generates a logical copy of the input signal through a new electrical pulse amplitude and waveform, and uses this electrical signal to drive The transmitter produces an optical signal with a new wavelength.
