Adapting OSAs to a New Spectral Response

FTB-5240S/BP Optical Spectrum Analyzer

Challenge

The spectral response of a 40 Gbit/s transmitter is far larger than that of 10 Gbit/s, depending on the modulation scheme, ripple, crosstalk and other problems that can be present. This can prove even more challenging when 10 Gbit/s and 40 Gbit/s are copropagating.

Test Solution

For error-free transmission, the industry-leading FTB-5240S/BP Optical Spectrum Analyzer easily characterizes DWDM signals, EDFAs, DFBs and spectral transmittance thanks to automated tests. The FTB-5240S/BP also has the industry's best optical rejection ratio at 12.5 GHz, as well as the sharpest bandwidth in field-ready OSAs.
