Bristol Instruments- 338 Series Optical Wavelength Meter

Fast and cost-effective wavelength measurement

The 338 Series Optical Wavelength Meter from Bristol Instruments combines speed and affordability to address the most important requirements of optical transceiver manufacturers.

The model 338 has a high measurement rate of 25 Hz that results in reduced testing times and greater production throughput. And, its affordable price point, along with a five-year warranty, provides the lowest cost of ownership compared with similar systems.

 

Guaranteed accuracy with continuous calibration

The 338 Optical Wavelength Meter uses proven Michelson interferometer-based technology with fast Fourier transform analysis to accurately measure the wavelength of CW and modulated signals.

Two versions are offered. The model 338A is the most precise, providing an accuracy of ± 0.3 pm. For less exacting test requirements, the 338B system is a lower-priced alternative with a wavelength accuracy of ± 1.0 pm.

Continuous calibration with a built-in wavelength standard maintains the performance of the 338 Optical Wavelength Meter over long periods of time. What’s more, every 338 system is rigorously tested with laser sources that are traceable to NIST standards.

 

Designed for convenience, built to last

Operation of the 338 Optical Wavelength Meter is straightforward.

The optical signal enters the model 338 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 -30 dBm (1 µW). Automatic attenuation instantly adjusts the signal for optimum performance.

A convenient touch-screen display on the instrument’s front panel controls the 338 system and reports the measured wavelength and power. The measurement data 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 338 Optical Wavelength Meter provides long-term reliable operation that is backed by a five-year warranty covering all parts and labor.
