The swept wavelength system (SWS) module is available to measure the wavelength dependency of passive optical elements with the MAP system.

It is used for the spectral measurement of optical DWDM components (i.e., for ROADMs, wavelength-selective optical switches, tunable filters, or optical circuit packs. The SWS system comprises the following

• Tunable laser
• Optical sources – source optical module (SOM)
• Receiver chassis
• Control module
• Detector module
• Application software

It is used to measure the following:

• Insertion loss – IL
• Return loss – RL
• Polarization-dependent loss – PDL
• Directivity

SWS System Features

• Up to eight measuring stations can be operated at one base
• Absolute wavelength accuracy ±0.002 nm
• Up to 256 detectors per receiver station
• Scanning speed up to 40 nm/s
• DLLs for customer-specific applications
