Wavelength measurement and spectral analysis for optical transceiver and WDM transmission system testing

Whether you design, develop, or manufacture fiber-optic communications components or systems, Bristol Instruments offers products that are specifically designed to precisely and efficiently test parameters such as wavelength and side-mode suppression ratio.

Bristol Instruments optical and multi-wavelength meters support R&D and production applications including:

Tunable Transmission Laser Testing
DFB Laser Testing
WDM Component Testing
WDM Transmission System Testing
Optical Test Equipment Calibration


Accurate, fast, and cost-effective

Wavelength is measured to an accuracy as high as ± 0.3 pm with a measurement rate as high as 1 kHz. Side-mode suppression ratio is measured automatically in less than 0.07 seconds.

An affordable price and a five-year warranty ensure the lowest cost of ownership.
