The trend of FTTX technologies is increasing rapidly, spurring the sharp demand for fiber optics components, especially optical passive components. This dramatic transformation is occurring because of the rising demand for internet-based communications and services among businesses and consumers. The transformation continues to accelerate at a quick pace, especially after the Covid-19 pandemic. As a
A 2000nm 3-port high-power PM optical circulator is a non-reciprocal, passive, and high-performance optical circulator with three ports, operating on a 2000nm wavelength and handling high power wattages while maintaining the state of polarization as well. While it functions like a microwave circulator, i.e. transmitting a light wave from one port to the next sequential
A bandpass filter is an optical component that allows only certain light frequencies to pass through it. The component has one input and two outputs; one output carries all the frequencies that are allowed to pass through, while the other output carries only the frequencies that have been rejected by the filter. In this article,
Before you know about inline polarizers, you should understand what polarization is. It is the direction in which the electric field of a light wave oscillates. An inline polarizer uses selective absorption, refraction, or transmission to turn unpolarized light into polarized light. It is a device that transmits light waves along one axis and absorbs
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
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
