Can an optical splitter be used as a signal amplifier
Optical splitters can be used to distribute optical signals to multiple terminal devices, such as sensors, detectors, receivers, and amplifiers, to achieve signal transmission and processing. Optical audio, often referred to as TOSLINK (Toshiba Link), is a technology that transmits audio signals in digital format through fiber optic cables. The primary advantage of optical audio is its ability to transfer high-quality sound without interference from electromagnetic signals. (My 4 speakers require too much power for only. An optical splitter, also known as a beam splitter, fiber splitter, or fiber optic splitter, serves as a vital passive component in optical communication systems.

Principle of Distributed Raman Amplifiers
In-line Raman amplifiers provide distributed gain along the optical fiber, significantly improving the optical signal-to-noise ratio (OSNR) compared to traditional lumped amplifiers like EDFAs, which enables longer transmission spans in long-haul terrestrial and submarine networks.

Raman amplification / ˈrɑːmən / is a way of increasing the signal strength in an optical fiber. It is often used in a fiber that carries a signal for a long distance (such as in an undersea cable). Technically, it works by stimulating Raman scattering, in which a lower frequency 'signal' photon. A Raman amplifier is an optical amplifier based on Raman gain, which results from the effect of stimulated Raman scattering in some Raman gain medium.
