Use it as a Wavelength Meter…

Optical Spectrum Analyzer Wavelength Accuracy

The 3 internal Wavelength calibrators (absolute and relative) allow the equipment to provide an excellent wavelength accuracy specification (+/- 3 pm). This high wavelength accuracy gives the possibility to use the equipment as a wavelength meter.

An ultra high dynamic and close-in dynamic range !

APEX Technologies Optical Spectrum Analyzers achieve more than 83 dB of dynamic. They also have the unique advantage to have this high dynamic really close to the peak. For example, when the best standard grating based OSA can achieve 78 dB at +/- 1 nm, APEX Technologies AP2040 series can achieve 80 dB at +/- 6 pm from the peak.

Perfect resolution filters for OSNR measurement !

Grating Based and Interferometric Based Optical Spectrum Analyzer Resolution Filter Shape Comparison

Several resolution filters between 250 GHz and 5 MHz are available.  APEX Technologies rectangular shape resolution filters allow a nearly perfect integration of the signal over the selected resolution, while a grating based Optical Spectrum Analyzer filter integrate inside a wide base triangular shape.
This sharp integration allows our OSA to perform a much more realistic level measurement, essential for an accurate OSNR measurement.

Two Optical Spectrum Analyzers channels, one per polarization axis !

The input signal is split into two orthogonal polarization axes, analysed simultaneously by two internal independent channels, APEX Technologies Optical Spectrum Analyzer has the unique advantage to display the two polarization channels separetely and simultaneously. It can also recombine them and display a polarization independent measurement.

Dual Polarization Optical Spectrum Analyzer



Two Optical Spectrum Analyzers in one equipment !

Optical Spectrum Analyzer 3 Inputs

Optionally, two additional PM inputs directly connected to each internal channels are available. With these 2 additional PM inputs, two independent signals can be analysed simultaneously.
By using this option, the equipment can be used as two Optical Spectrum Analyzers !

Use it as a Tunable Laser Source…

Optionally, the built-in Tunable Laser Source can also be used as an independent Tunable Laser Source. A Tunable Laser Source output and a control software can be integrated into the equipment. This C, L or C+L band Tunable Laser Source is combining narrow linewidth, good SMSR and fine wavelength setting resolution.

Use it as an Optical Spectrum Component Analyzer…

Optical Component Transmission Analysis

The Tracking generator option allows the user to synchronise the Tunable Laser Source output with the Optical Spectrum Analyzer measurement, thus active and passive components transmission measurements (insertion loss/gain) are possible with a dynamic range of 63 dB and a resolution of 1 MHz (8 fm). This function is really useful for Fibre Brag Grating characterization.
