With the rapid development of the Internet, the transmission distance of twisted pair cables and the influence of electromagnetic interference are limited, which restricts the development of the network. Therefore, gigabit fiber optic transceivers appeared. Fiber optics can be used to replace the connection medium in Ethernet with fiber optic transceivers. Fiber optics, low loss and high resistance to electromagnetic interference. By extending the network transmission distance from 200 meters to 2 kilometers to tens of kilometers, or even hundreds of kilometers, the quality of data communication is greatly improved.
Single Mode Single Core Fiber Transceiver
Optical fiber transceivers are photoelectric conversion devices that convert Ethernet electrical signals and optical signals to each other. By converting electrical signals into optical signals and transmitting them on multi-mode or single-mode optical fibers, optical cables have short transmission distance limitations, so Ethernet networks can use optical fiber media to achieve several kilometers or even several kilometers under the premise of ensuring high-bandwidth transmission. Long-distance transmission of 100 kilometers.
Advantages of gigabit fiber optic transceivers:
There are many benefits to using fiber optic transceivers. For example, fiber optic transceivers can extend Ethernet transmission distances and extend Ethernet coverage. Optical fiber transceivers can convert between 10M, 100M or 1000M Ethernet electrical interfaces and optical interfaces; using optical fiber transceivers to build a network can save network investment; optical fiber transceivers enable servers, repeaters, hubs, terminals and terminals to communicate with each other. Even faster. Fiber optic transceivers feature microprocessors and diagnostic interfaces that provide various data link performance information.
Application scenarios of single-mode single-core optical fiber transceivers
How to distinguish single fiber optical transceiver and dual fiber optical transceiver?
When a gigabit fiber optic transceiver is embedded in an optical transceiver, the optical transceiver is divided into a single fiber transceiver and a dual fiber transceiver according to the number of cores of the connected fiber jumper. The linearity of the fiber patch cord connected to the single fiber transceiver is a core responsible for transmitting and receiving data. A patch cord connected to a dual-fiber transceiver has two cores, one of which is responsible for transmitting data and the other for receiving data. When the optical module does not have an embedded optical module, it is necessary to distinguish whether it is a single-fiber or a dual-fiber according to the inserted optical module. When a single-fiber bidirectional optical module is inserted into an optical transceiver, that is, the interface is a simplex type, the optical transceiver is a single-fiber transceiver. When the optical transceiver is inserted into the dual fiber bidirectional optical module, the interface is dual interface. This type of transceiver is a dual fiber transceiver.
