光纤收发器与协议转换器的区别（Difference between fiber optic transceiver and protocol converter） The fiber optic transceiver is a physical layer device, a device for converting optical fiber to twisted pair, with 10/100/1000M conversion. There are many kinds of protocol converter, the majority is basically is a 2 layer device, a RAD protocol converter is often met with the E1 line 2M into V.35 data line connected to the router equipment, of course, 2M twisted pair Ethernet, remote access via 2M communication lines can realize LAN and expand. The two devices do not maintain much of it. As long as it doesnt burn, its not bad. A router is a device with more than 3 layers, and you need to have a lot of knowledge about router configuration. Different brands of different ways of use, you need to have targeted learning. Agreement。 Optical transceiver is a light signal twisted pair signal of short distance and long distance Ethernet transmission media conversion unit swap, in many places, also known as photoelectric converter or optical fiber converter (Fiber Converter). Fiber optic transceivers are generally used in Ethernet cable can not cover, must use fiber to extend the transmission distance of the actual network environment, at the same time to help the last mile fiber line connected to metropolitan area network and the outer network also played a huge role. With fiber transceivers, it also offers an inexpensive solution for users who need to upgrade the system from copper wire to fiber, but lack funds, manpower or time. In order to ensure full compatibility with other manufacturers, network repeaters, hubs and switches and other network equipment, optical fiber transceiver products must strictly comply with 10Base-T, 100Base-TX, 100Base-FX, IEEE802.3 and IEEE802.3u Ethernet standard. In addition, in the EMC anti electromagnetic radiation should be consistent with FCC Part15. At present, because the major domestic operators are vigorously building residential networks, campus networ
