Optical fiber communication has become an integral part of modern communication networks. Several transmission bands, from the original O-band amplifier to the U / XL band, are defined and standardized in fiber optic communication systems.
Optical amplifiers are also used at other places in a network, such as within an optical switching node to compensate for switch fabric losses. Semiconductor Optical Amplifiers, or SOAs, have shown to be capable and multipurpose devices that serve as critical building blocks for optical networks.
As a result, several functions have been achieved by adjusting the optical signal purely in the optical region. Here we have summarized some of the critical features of O- band amplifiers.
