Modern telecommunications systems are capable of moving vast amounts of information through optical fibers. In order to maximize the amount of information, a variety of closely spaced wavelengths are combined using wave division multiplexing. Gratings are a vital part of these advanced networks as they allow for the management of these wavelengths by separating the wavelengths so that the information can be routed and manipulated. The gratings below are suitable for use in the spectrum used by telecommunications.
Our datacom/telecom diffraction gratings are listed in order of decreasing groove frequency. Click on a Master Grating Code (last 4 digits of a grating's part number) below to view master grating efficiency curves. Use the request a quote to get a quote based on your requirements.
