Series Capacitor It is connected in series capacitor to compensate the inductive reactance of line. This reduces the transfer reactance between the buses to which the line is connected. It increases maximum power that can be transmitted and reduces reactive power loss. The reactive power produced by the series capacitor increases with increase in power

WDM – Wavelength Division Multiplexing A distinctive operational feature of an (WDM wavelength division multiplexing) optical fiber is that there is a wide spectral region in which optical signals can be transmitted efficiently. For full- spectrum fibers this region includes the O-band through the L-band, which ranges from about 1260 to 1675 nm. Since the

Optical Receiver Operation Having discussed the characteristics and operation of photodetectors in the previous chapter, we now turn our attention to the optical receiver operation. An optical receiver consists of a photodetector, an amplifier, and signal processing circuitry. The receiver has the task of first converting the optical energy emerging from the end of a
