Legendary source stability

What it does:

  • High quality fiber connected sources with low loss interchangeable connectors improve test source stability. For example, we specify the source re-connection repeatability as 0.1 dB.
  • We accurately set the laser power, so power meter referencing is a more reliable process. The actual power will be very close to the nominal power.
  • SM lasers have a tight 20 nm wavelength tolerance, for improved long distance test repeatability.
  • MM LEDs are mode controlled to meet Encircled Flux requirements with no additional conditioning patch leads.
  • The Autotest feature has high functionality with data transfer, This reduces laser warm up, so also makes measurements more stable.

User benefits

  • Typical users will get accurate and repeatable loss test results under all conditions.
  • Save time with less referencing
