An optical amplifier amplifies light as it is without converting the optical signal to an electrical signal, and is an extremely important device that supports the long-distance optical communication networks of today. The major types of optical amplifiers include an EDFA, FRA, and SOA.
New 5G optical network architecture requires high bandwidth and low latency. Therefore, the providers of fiber optic cables are all gearing up to meet the challenges to manufacture new 5G related products for 5G network deployment.
