Bristol 438 Series Multi-Wavelength Meter

Accurate, reliable, and fast WDM wavelength testing

Bristol Instruments

The 438 Series Multi-Wavelength Meter from Bristol Instruments combines proven Michelson interferometer-based technology with fast Fourier transform analysis in order to measure the wavelength, power, and OSNR of as many as 1000 discrete optical signals.

 

With features such as high accuracy, measurement rate up to 10 Hz, and a broad operational range of 1000 to 1680 nm, the model 438 provides the most precise, efficient, and versatile wavelength testing of laser transceivers and WDM signals. To verify the accuracy of the model 438, every system is rigorously tested with laser sources that are traceable to NIST standards.

 

Features:

  • Optical wavelength measured to an accuracy as high as +/-0.3pm
  • Continuous calibration with a built-in wavelength standard
  • Measurement confidence level of > 99.7%
  • Traceable to NIST standards
  • Power measured to an accuracy of ± 0.5dB
  • Automatically calculates OSNR to >40dB
  • Automatic reporting of SMSR via SCPI
  • Fastest measurement rate of 10Hz for reduced testing times
  • Broad operational range of 1000nm to 1680nm
  • Operates with CW and modulated signals
  • Convenient touch-screen display reports measurement data in a variety of formats
  • Interfacing via SCPI using USB, Ethernet or GPIB
  • Rugged design for manufacturing environments
  • Includes 5 year warranty

Operation of the 438 Multi-Wavelength Meter is straightforward. The optical signal enters the model 438 through an FC (UPC or APC) fiber-optic connector on the front panel. The system’s high sensitivity results in an input power requirement as low as -40 dBm (0.1 µW). Automatic attenuation instantly adjusts the signal for optimum performance.

 

A convenient touch-screen display, located on the front panel, controls the 438 system and displays the measured wavelength, power, and OSNR in a variety of formats. Data from a specific optical channel can be displayed, or lists of data from all channels, sorted by wavelength or power, can be reported.

 

The measurement information can also be sent to a PC using a library of SCPI commands via standard USB or Ethernet interface, or an optional GPIB interface.

 

The rugged design of the 438 Multi-Wavelength Meter provides long-term reliable operation, backed by a five-year warranty on all parts and labor. This results in less downtime and the lowest cost of ownership available.
