Advanced Optical Components – Optical Switch

Optical switch (or fiber optic switch) can be a mechanical, opto-mechanical, or electronic device that opens or closes an optical circuit. The optical switch can be used to complete or break an optical path. Passive fiber optic switches will route an optical signal without electro-optical or opto-electrical conversion. However, a passive optical switch may use […]

The Evolution of Fiber Transmission in Optical Communications

Optical communication systems’ transmission capacity continues to be increasing forever. From telegraph systems carrying a few clicks per second a hundred years ago, towards the state-of-the-art, long-distance, DWDM Network systems carrying over one Tbps today, the capacity of wired long-haul systems has burgeoned in an average annual increase of around one third (or perhaps a […]
