UPS power system switching
The three general categories of modern UPS systems are on-line, line-interactive and standby: • An online UPS uses a "double conversion" method of accepting AC input, to DC for passing through the (or battery strings), then inverting back to 120 V/230 V AC for powering the protected equipment.

Attenuation Principle of Passive Optical Networks
An optical attenuator is a passive device that reduces optical power in a controlled way without changing the signal format. PON system should include an optical distribution network (ODN), optical line terminal (OLT), and optical network unit (ONU). Firstly, ODN is an FTTH (fiber to the home) optical network based on PON equipment, which provides an optical transmission channel. Attenuation is a term in communication that refers to loss (reduction) in signal strength when a signal is transmitted from sender to the receiver. This loss happens due to a variety of factors. It is measured using decibels (dB). It contains optical absorption materials and is used to reduce the power of optical signals in optical fibers. for achieving a suitable signal level for a data receiver in a telecom system.
