Standard Optical Interleaver
-
An innovative technique for expanding the number of channels per fiber involves an optical device, called an optical interleaver. For example, in most DWDM equipment, the standard channel spacing is 100 GHz. But spacing the signal-carrying frequencies every 50 or even 25 GHz can double or even quadruple the number of channels per fiber. This job is accomplished by an optical interleaver. Such a device takes two multiplexed signals with 100-GHz spacing and interleaves them, creating a DWDM signal with channels spaced 50 GHz apart. The process can be repeated, creating even denser composite signals with 25-GHz or 12.5-GHz spacing. The signals at the receiving end are recovered with the same devices used as splitters or optical de-interleavers. Thus, devices and/or networks can be upgraded without requiring that all devices be upgraded, or network bandwidth can be increased.

OZ Optics offers a broad range of both variable and fixed attenuators having key competitive advantages. All of our attenuators operate over the two standard wavelength bands, the C-Band and the L-Band. This wide wavelength range makes these components ideal for DWDM applications. Our attenuators are wavelength insensitive, which means they operate with minimal changes in attenuation when used in either the C-Band or the L-Band and exhibit low return loss. In addition, all of our attenuators have a wide attenuation range, which means they operate at a wide range of power levels. This is important as increased power levels are being used in newer optical systems.
