The Next-Generation, Scalable Solution for Communications Network Testing

DWDM Module

The DWDM Module tackles the toughest DWDM network installation and maintenance problems with ease. A spectrum display, wavelength drop, and wavelength converter is a one-two-three punch combination that can't be beat. The spectrum display across the C-Band and L-Band reveals physical layer problems with wavelength, power levels, and OSNR. Its fast spectrum scan takes less than 1.5 seconds, making network changes immediately apparent.

By transmitting on and dropping out individual DWDM channels, the STT DWDM brings the advantages and precision of BER testing to DWDM networks. Never before has such comprehensive payload analysis been possible from within the DWDM network. Use the wavelength drop feature in combination with the STT SONET/SDH or Ethernet test functions to dig into each channel. The wavelength converter feature saves a ton of money, since it's like having a channel card for each ITU-T 50GHz wavelength. The tunable laser source inserts a SONET/SDH, OTN or Ethernet signal onto the DWDM network to facilitate network construction and troubleshooting.

• C and L-Band channel analysis spectrum display
• Power level, wavelength, and OSNR for each DWDM channel
• 1.5 second scan time for real-time monitoring
• Dual ports for monitoring both sides of a Network Element
• Internal tunable laser source inserts your SONET/SDH signal onto the DWDM network
• Wavelength drop filter for comprehensive analysis with STT SONET/SDH and Ethernet test functions
• Individual features can be ordered separately and work in stand-alone mode, for easy integration with other lab equipment
