| The demand for access to larger volumes of digital information continues to force telecommunications operators to increase the capacity of their transmission systems. The bandwidth of these systems is increased by employing dense wavelength division multiplexing (DWDM) technology. This technique couples multiple optical carrier signals onto a single optical fiber by using different laser wavelengths. This requires stringent performance criteria be met to ensure quality, uninterrupted communications. In particular, the ability to accurately measure optical wavelength is necessary to characterize and optimize DWDM components such as transmission lasers, and the optical signals from DWDM transmission systems. Bristol Instruments has developed a family of optical wavelength meters specifically designed for DWDM testing applications. These instruments are ideal for the precise wavelength characterization of tunable DWDM lasers, DFB lasers, and VCSELs. They can also be used to calibrate passive DWDM component test equipment such as optical spectrum analyzers (OSAs). Bristol Instruments also offers multi-wavelength meters for testing DWDM signals. Wavelength, power, and OSNR of as many as 250 optical channels can be measured simultaneously to fully characterize a DWDM transmission system. |
