Features:

* Wavelength scan in less than 1sec
* Wavelength accuracy: +- 2 ppm for laser lines separated by > 15GHz
* High Laser Input power: 10dBm (18dBm - Safe Input level)
* Built-in HeNe laser wavelength standard

Benefits:
* The wavelength accuracy gives you the certainty of accurate channel characterization
  in dense WDM systems, to detect channel's wavelength shift and crosstalk between
  adjacent channels.
* The high input power level enables you to test transmitter without additional
  connections and instruments (e.g. attenuator).
* The built-in HeNe guarantees an accurate absolute wavelength measurement real-time
  determined against the standard anytime and ensures accurate and reproducible
  experimental results.
