The optical transceiver is an Ethernet transmission medium conversion unit that exchanges short-distance twisted pair electrical signals and long-distance optical signals. In many places, it is also called a Fiber Converter.
When it comes to fiber optic transceivers, people often inevitably compare fiber optic transceivers with switches with optical ports. The following mainly talk about the advantages of fiber optic transceivers relative to optical port switches.
First of all, the optical transceiver plus the ordinary switch is far cheaper than the optical port switch, especially some optical port switches will lose one or even several electrical ports after adding the optical module, so that the operator can largely Reduce upfront investment.
Secondly, since most optical modules of the switch do not have a unified standard, once the optical module is damaged, it needs to be replaced by the same module from the original manufacturer, which brings great trouble to the later maintenance. However, there are no problems in the interconnection and intercommunication between the devices of different manufacturers of optical transceivers. Therefore, once damaged, they can be replaced by other manufacturers' products, which is very easy to maintain.
In addition, the optical transceiver is more complete than the optical port switch in the transmission distance. Of course, the optical port switch also has advantages in many aspects, such as unified management and unified power supply, which will not be discussed here.
