Optical fiber switches

The switching speed of electronics can never match the transmission capacity offered by the optics. This paper basically describes some basic kinds of optical switches. Behaviour of different optical switches i.e. OEO (Optical-Electrical-Optical) and OOO (Optical-Optical-Optical) switches is discussed with reference to open source optical communication. Some basic technologies used for optical switching along with their pros and cons are also presented in this paper.
