What you should know about the transceiver

When using fiber optic transceivers, many friends will encounter such questions:
1 fiber transceiver must be used in pairs?
2 Is there a fiber optic transceiver that is one or both? Or can it be used as a pair of fiber optic transceivers?
3 If the fiber transceivers must be used in pairs, is it true that the pair is the same brand and model? Or can the casual brands be used in combination?
What is it like? Let's take a look at this little blog!
Optical transceivers are generally used in pairs as photoelectric conversion devices, but it is also possible to use optical transceivers with fiber switches, fiber transceivers, and SFP transceivers. In principle, as long as the optical transmission wavelength is the same, the signal package Fiber communication is achieved by the same format and supporting a certain protocol.
Generally, single-mode dual-fiber (two fibers required for normal communication) transceivers are not divided into the transmitting end and the receiving end, and can be used as long as they appear in pairs.
Only the single-fiber transceiver (which requires one fiber for normal communication) will have a split transmitter and a receiver.
Whether it is a dual-fiber transceiver or a single-fiber transceiver to be used in pairs, different brands are compatible. But the rate, wavelength, and mode are the same.
That is to say, different rates (hundreds of megabytes and gigabytes) and different wavelengths (1310nm and 1300nm) cannot communicate with each other. In addition, even a single-fiber transceiver of the same brand and a pair of dual-fiber and dual-fiber pairs are formed. It is also not interoperable.
