1550nm 5W Single Wavelength DFB Erbium-doped Fiber Laser Module Manufacturers

DWDM(Dense Wavelength Division Multiplexing): is the ability to combine a group of optical wavelengths with a single optical fiber for transmission. This is a laser technology used to increase bandwidth on existing fiber optic backbone networks. More precisely, the technology is to multiplex the tight spectral spacing of a single fiber carrier in a specified fiber in order to utilize the achievable transmission performance (for example, to achieve the minimum degree of dispersion or attenuation). In this way, under a given information transmission capacity, the total number of optical fibers required can be reduced.

This paper mainly introduces broadband light sources and its function.

As an important part of optical fiber communication system, optical module plays the role of photoelectric conversion. This article will introduce the core devices of the optical module.

Time-domain OCT is mainly composed of Michelson interferometers. The light emitted by the light source is divided into two beams after passing through the coupler, and enters the sample arm and the reference arm of the Michelson interferometer respectively.

High power ultrafast lasers are widely used because of their short pulse duration and peak power.Ultrafast lasers are used in material processing applications, medical fiber lasers, microscopy and other fields.
