Optical wavelength-division multiplexing (WDM) routing system for parallel computer
SPIE Proceedings, 2002This paper has reported the research of a scalable wavelength division multiplexing (WDM) optical routing system applied to the interconnection between CPU and MEM of distributed parallel computer. This system is built on DWDM and the optical switch array, which can connect CPUs and MEMs in a multigigabit WDM fiber, and so take advantage of high ...

Low-loss wavelength division multiplexing (WDM) devices for single-mode systems
Journal of Lightwave Technology, 1983We report here on single-mode microoptic wavelength division multiplexing (WDM) devices with two channels located at 1275 and 1345 nm, respectively. Data are presented for four multiplexers and four demultiplexers. The average insertion loss for the multiplexers was 0.5 ± 0.2 and 1.0 ± 0.3 dB for the short and long wavelength channels, respectively ...

WDM and optical amplifier (Wavelength Division Multiplexing)
2010 2nd International Conference on Mechanical and Electronics Engineering, 2010Wavelength Division Multiplexing (WDM) is the basic technology of optical networking. It is a technique for using a fibre (or optical device) to carry many separate and independent optical channels. The principle is identical to that used when we tune our television receiver to one of many TV channels.

Environmental Testing Of Wavelength Division Multiplexers (WDM)
SPIE Proceedings, 1987Optical wavelength division multiplexers (WDM) were tested for performance degradation as a result of temperature cycling, shock and pulling on the fiber leads to determine tensile strength. The WDM components tested use multidielectric coatings to separate two channels, one ranging from 0.75 to 0.95 micron and the other from 1.2 to 1.6 microns.

Wavelength Division Multiplexing (WDM)
2021Wavelength division multiplexing or WDM allows the combining of a number of independent information-carrying wavelengths onto the same fiber, because of the wide spectral region in which optical signals can be transmitted efficiently. This chapter addresses the operating principles of WDM, describes a wide array of optical sources and passive ...

A Review of Data Transport Employing Wavelength Division Multiplexed (WDM) Transmission
Journal of Advances in Science and Technology, 2023The term "high performance networks" describes optical networks. Through optical networks, massive amounts of data may be delivered at incredible speeds. Electromagnetic interference and other forms of outside impact do not affect optical networks. For a variety of uses, optical systems provide increased information transmission capacity at reduced ...

Wavelength Division Multiplexing/Demultiplexing (WDM) Using Diffraction Gratings
SPIE Proceedings, 1984This paper reviews the present status of diffraction grating based wavelength division multiplexer/demultiplexers (WDM). A comparison is made of WDM's currently in commercial use with both monomode and multimode fibres. Devices are described ranging from an industrial system multiplexing and demultiplexing 49 channels to a 12-channel monomode ...

MCDQDB (Multi-channel DQDB) using WDM (wavelength division multiplexing)
Proceedings of GLOBECOM '95, 2002Applications such as real-time video/voice service, distributed multimedia database access, and high-resolution image transfer require more bandwidth than is available today. These applications also require a large geographical span. To meet these requirements, we introduce the new protocol, MCDQDB, for a multi-channel dual-bus MAN which is the ...
