Fiber optic transceivers allow for much higher data transmission speeds and ability to transmit data over longer distances compared to copper. Some key advantages of fiber include: - Fiber is not limited by skin effect like copper and can transmit data up to 100km. - Fiber allows for more data capacity as well as long distance communication without radiation. - Fiber is used widely in telecom and datacom networks for technologies like Ethernet, SONET, SDH, and more.
