Rated operating current of secondary distribution box

Most modern secondary networks are operated at AC rated voltage of 100–120 or 230–240 volts, at the frequency of 50 or 60 hertz. Operating voltage, required number of phases (three-phase or single-phase). [pdf]

Switch Solidified Optical Mode

Multimode optical switch is a key component of mode division multiplexing in modern high-speed optical signal processing. In this paper, we introduce for the first time a novel 2 × 2 multimode switch design. [pdf]
