Attenuators
-
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.

Multiplexers (MUX)
WDM
-
It is highly desirable to reduce the number of cables required to communicate between spaces on Navy ships due to increased weight, cost and maintenance concerns. To reduce weight and expense, copper-based NTDS parallel and serial type cables can be converted to fiber optic and multiplexed using Wavelength Division Multiplexing (WDM) technology. WDM technology allows for multiple fiber optic wavelengths to be combined in a single fiber and then separated back to individual fibers at the distant end. Using Coarse WDM (CWDM) which utilizes wavelengths 20nm apart ranging from 1271 nm to 1611 nm, provides for up to 18 optical wavelengths to be combined into a single fiber. Optionally Dense WDM (DWDM) can be used allowing for up to 160 optical wavelengths.
