9.6 Tbit/s DWDM equipment's been created A 100 Gbit/s signal has been transmitted for a distance of 4,250 km

Optical spectrum analyzer OPM

Measurements of the spectra in DWDM systems

  • C-band 1528 — 1558 nm
  • Frequency grid 50 GHz
  • 4-lines optical switch

The unit performs spectrum measurement for signal rates 2.5 Gbit/s (direct and external modulation), 10G, 40G and 100G (with limitations). Channel optical power can be measured in the range -40…-10 dBm. Noise floor is -55 dBm. The unit is managed using a web interface that displays the spectrum of multi-channel optical signal and a list of channel powers for different formats of modulation. The unit is designed for use in the “Volga” chassis.
