Bit error ratio (BER) measurement is the fundamental measurement of the quality of the fiber optic communication system It measures the system's probability that transmitted bits will be correctly received as logic ones and zeros

The structure of an optical receiver is simple: consisting of just a photodiode to produce the electrical current and an amplifier But do not be fooled: it is far more complex to design a really high performance optical receiver

What happens if a major fiber optic cable is cut or a major hubbing location is destroyed in a fiber network Will the whole system be brought down

What are fiber optic sensors The fundamental characteristic of all fiber optic sensors is that they depend on some optical properties, such as intensity, phase, state of polarization and wavelength, to be modulated by measurands

In the last decade, a wide variety of applications have been developed that covers a dozen of datacom networking technologies The transmission speed ranges from 10Mbits up to 10Gbit/s and growing

Do you know why it is so expensive to install Fiber To The Home Why Bell companies are reluctant to deploy fiber optic network directly to consumers in a large scale

Why Do We Need Fiber Optic Attenuators A fiber optic attenuator, also called an optical attenuator, simulates the loss the would be caused by a long length of fiber

Understanding FTTH (Fiber To The Home) FTTH is an all-fiber connection to the home which provides a minimum of 155Mbps bandwidth on both up stream and down stream directions Basically, it is composed of a fiber from the service node to the optical splitter, the optical splitter which separates to (fan out) terminate on single home ONU

What is all-optical switching All-optical switching is a process by which light, usually in the form of digital communication signals, is routed from one transmission channel to another, or modulated, without intermediate conversion to another format

What is an optical circulator The optical circulator has similar function and design as the optical isolator
