In essence, the optical fiber transceiver only completes the data conversion between different media, which can realize the connection between two switches or computers within 0-100Km, but the actual application has more expansion.
1. Realize the interconnection between switches.
2. Realize the interconnection between the switch and the computer.
3. Realize the interconnection between computers.
4. Transmission relay: When the actual transmission distance exceeds the nominal transmission distance of the transceiver, especially when the actual transmission distance exceeds 100Km, when the site conditions permit, two transceivers are used for back-to-back relay. Very cost-effective solution.
5. Single-multi-mode conversion: When single-multi-mode fiber connection is required between networks, one multi-mode transceiver and one single-mode transceiver can be connected back to back, which solves the problem of single-multi-mode fiber conversion.
6. Wavelength division multiplexing transmission: When the long-distance optical cable resources are insufficient, in order to increase the utilization rate of the optical cable and reduce the cost, the transceiver and the wavelength division multiplexer can be used together to transmit the two channels of information on the same pair of optical fibers.
