Optical Communication Technology: Principles, Applications and Current Issues

Course Contents:
We are moving towards the "lightwave web" era. This is creating a variety of new professional opportunities related to fiber optics. These opportunities range from the field technician, needed for fiber network installation and testing, to law professionals who face questions of fiber's right-of-way in power transmission lines, motorways, railways, oilducts etc. Also, marketing and sales professionals are facing growing interests in fiber and wavelength swap and leasing deals. On the other hand, the telecom industry continuously manufactures equipments and develops new optical communication technologies, demanding highly capable professionals that only excellence centers can offer. This course teaches fundamental and advanced knowledge of optical fiber communications. It is intended towards decision making professionals with and without technical background.
