With the AP204xB series and the AP205xA series, Apex Technologies sets a new standard in Optical Spectrum Analysis. Its different approach enables it to measures in far greater detail than ever before.

The AP204xB series is based on an intereferometric principle which is able to achieve a 0.04pm resolution (5MHz), a +/-3pm absolute wavelength accuracy and a close-in dynamic range of 60dB at +/-3pm.
The AP2050A series is based on an intereferometric principle which is able to achieve a 0.16pm resolution (20MHz), a +/-3pm absolute wavelength accuracy and a close-in dynamic range of 50dB at +/-6pm.

With a price in the same order as conventional monochromator based OSA's, it makes the Apex Technologies OSA's the first of its kind in the next generation Optical Spectrum Analyzers.

While monochromator based Optical Spectrum Analyzers can achieve a maximum resolution of 10pm, the AP204xB series is based on an intereferometric principle which is able to dramatically increase this resolution by a factor 250, achieving a 0.04pm resolution (5MHz). Achieving such a high resolution with a monochromator will require a 12 meters long equipment (with all the drawback of this kind of configuration)!

Thanks to the ultra high resolution of the AP204xB series and AP205xA series, channel and even modulation types can easily be identified.
In D-WDM systems low channel crosstalk is crucial for optimum system performance and can easily be analyzed due to the AP204xB's 0.04pm wavelength resolution, and adjusting channels in the ITU grid is no longer a challenge thanks to the +/-3pm absolute wavelength accuracy of the AP204xB series and AP205xA series.
