As voice, video, and data traffic continue to increase, improving the flexibility and capacity of optical networks is a pressing challenge. Multiband optical filters have been used in applications as varied as astronomy, fluorescence spectroscopy, and 3D cinema. The...
The rapid expansion of the World Wide Web and increased connectivity requirements have generated an explosion in optical communication systems. In optical fiber-based communications, optical signals are transported on a light wave. Each wavelength (or frequency) of...
The demands placed on networks by voice, video and data are increasing exponentially. Thus, service providers require more bandwidth and higher transmission speeds. However, deploying fiber cabling for each service is costly. Transceiver-based solutions add more...
Long pass filters, sometimes referred to as long pass edge filters, are designed to transmit wavelengths within a given wavelength range. This band is defined by the filter’s cut-on edge which essentially blocks frequencies shorter than the specified edge wavelength....
Dichroic filters are designed to selectively allow wavelengths within a specific transmission band to pass through while reflecting all other colors and for beam steering purposes. They are particularly useful in optical applications where the detector is...
A simple approach in optical data communication is the use of a pair of optical fibers for a single channel transmission. The fiber pair provides the two directions for transmitting the data. Basically, one pair of fiber is equivalent to one data channel and the light...
Optical interconnect technology is the successor to conventional electrical interconnects. Particularly in telecommunications, it was an obvious and essential step from electrical to optical interconnects to cope with the ever-growing demand for higher bandwidths,...
