Erbium-doped fiber amplifiers (EDFAs) are special types of optical amplifiers meant to provide discreet amplification. Discreet amplifiers are often used as boosters, pre-amplifiers, or in-line amplifiers. Sometimes, they are also used to compensate for the loss of additional elements such as DCM, which is often located between the fiber spans. How is a typical EDFA
Fiber lasers are revolutionizing the world of manufacturing, telecommunications, and even medicine. These incredible devices are capable of delivering large amounts of power and fast pulses of light at very high accuracy, making them the perfect choice for jobs like cutting through metal or removing heat from damaged equipment without damaging the equipment itself. With
An optical fused coupler is a fiber optics device designed to connect one or more fiber ends to transmit light signals in multiple paths. It can be used to either combine two or more inputs into a single output or divide a single input into two or more outputs. In this blog, you will learn
The small pieces of cable in fibers that are capable of polarizing the incoming light signals are known as in-line polarizers. The reason why these devices are known as in-line polarizers is that they are positioned in-line with the fiber. With the help of this, fiber can produce output signals with optimum intensity and bandwidth
WDM stands for Wavelength Division Multiplexing which is a technique of multiplexing (combining) multiple optical carrier signals of varying wavelengths via a single optical fiber. Hence, WDM makes it possible to allow communication in both directions through a single fiber cable. In this blog, we will discuss how a fused WDM coupler fits in the
An optical circulator is an optical passive component based on the non-reciprocal polarization of an optical signal by the Faraday Effect. In this blog, we will discuss different facts about a PM optical circulator that will help you learn more about these components. It’s a Three-Port Device. Unlike other passive components, a PM optical circulator
Simply defined, a cladding power stripper is a device that removes light from a fiber cladding. The device removes any light that travels in the cladding, ensuring that the measurements are based only on the effects of the core and not the cladding. The cladding power stripper is designed for the applications such as high-power

Also known as a pump coupler, the pump combiner is an optical passive component that is used for sending pump and signal light into an amplifier or laser fiber. As pump combiners are used in varied applications, they are specially designed for high-power use. The high power of the combiner makes its use easy and
An optical filter is a small device designed to selectively transmit light of certain wavelengths. Each optical filter is characterized by its frequency response which specifies how the magnitude and phase of each frequency component of the incoming signal are altered by the filter. Mostly optical filters belong either to the category of absorptive filters
