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 […]
Optical Switch Tutorial from Fiberstore
What is an Optical Switch? Optical Switch is a switch that enables signals in optical fibers or integrated optical circuits (IOCs) to be selectively switched from one circuit to another in telecommunication. Away from telecom, an optical switch is the unit that actually switches light between fibers, and a photonic switch is one that does this […]
Applications of Fiber Optics in communication systems
The use of fiber optic systems is expanding at a amazing rate. Only in the past Ten years, fiber optic communications systems have replaced just about all coaxial and twisted pair cables particularly in network backbones. This is also true in almost any long distance communication links. This can be explained simply. Optical fiber cable […]
Optical Passive Categories Introduction
Optical passive devices is an important part of the communication device, but also the other optical components indispensable application areas. There are mainly four categories of Optical Passive. (A) Active Fiber Optic Cable Connector Fiber optic cable connector is connected to two active optical fiber to form a continuous optical path and can be repeated […]
All-optical Switch Introduction
The all-optical switch is the main element in the optical communication network. As the key to realize all optical network, it has a low pumping power, high switch efficiency, fast response time characteristics, so much attention in recent years has been paid. From the late 1980s to the present, many research groups have conducted in-depth […]
