DWDM optical spectrum analyser

5 June 2002 Test & Measurement

NetTest has launched WALICS-Reference, a benchtop DWDM Optical Spectrum Analyzer that allows engineers to perform detailed analysis of transmission channels in DWDM systems. Operating from 1250 to 1650 nm, WALICS has been optimised for the S, C and L bands as well as for potential monitoring wavelengths. It features a sharp and narrow spectral response, and combines high resolution with high dynamic range that enables accurate optical SNR measurements in DWDM systems down to 12,5 GHz spacing.

WALICS-Reference also provides high-level software solutions through a user-friendly interface that includes WDM tables and statistics, an EDFA testing application and source characterisations. Using its flat-top filter mode, WALICS can be used to isolate one specific channel for additional testing, such as BERT. In addition, WALICS-Reference boasts a ±10 pm wavelength accuracy over the wavelength range.
