Product details for Wavelength Division Multiplexer

WDM FWDM can be widely used in system monitoring, fiber optical amplifiers, WDM networks and fiber optics instrumentation. As a professional and reliable manufacturer of fiber optic passive components

Wavelength division multiplexer (WDM) is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths (i.e., colors) of laser light. This technique enables bidirectional communications over one strand of fiber, as well as multiplication of capacity. Wavelength-division multiplexing (WDM) are design to address the specific requirements of the FTTH market based on thin-film filter technology. They are widely used in the combined transmission system of voice,data videl signal.

The term wavelength-division multiplexing is commonly applied to an optical carrier (which is typically described by its wavelength), whereas frequency-division multiplexing typically applies to a radio carrier (which is more often described by frequency). Since wavelength and frequency are tied together through a simple directly inverse relationship, in which the product of frequency and wavelength equals c (the propagation speed of light), the two terms actually describe the same concept.

Wavelength division multiplexing is a kind of frequency division multiplexing – a technique where optical signals with different wavelengths are combined, transmitted together, and separated again. It is mostly used for optical fiber communications to transmit data in several (or even many) channels with slightly different wavelengths. In this way, the transmission capacities of fiber-optic links can be increased strongly, so that most efficient use is made not only of the fibers themselves but also of the active components such as fiber amplifiers. Apart from telecom, wavelength division multiplexing is also used for, e.g., interrogating multiple fiber-optic sensors within a single fiber.
