All-Band Optical Component Tester


MT9820A has been designed to be the most versatile, compact and low price solution for customers who want to perform optical loss measurements over a wide wavelength range. It builds the bridge between the two previous traditional approaches: own built set-up based on step by step measurement, and complete integrated sweeping systems.

MT9820A adapts to any tunable laser source. Its compact format as well as its open architecture makes it the best mate of optical engineers and technicians who need a reliable low cost instrument to test or validate their design in a fast and accurate way.

Fast and accurate loss measurement for everyone
When it comes to measure optical transfer function, the sweeping method is the only fast and reliable solution. Sweeping measurement is not only faster than step by step measurement but also gives more sampling points and better wavelength accuracy. Nevertheless, most of tunable laser sources are still use in step by step mode because it is easier to implement in conjunction of power meters and a wavemeter. Building sweeping set-up is more difficult as it needs to do real time acquisition for power and wavelength measurements. The quality of the tunable lasers sources is also a key of success: mode hops, sweeping velocity, power flatness, wavelength accuracy… are various phenomenon that needs to be controlled in order to do reliable measurement. MT9820A brings all these knowledge, controls and accurate measurement capabilities in a simple box that easily interface with customer tunable laser and PC.

A tool that adapt to your needs
Complete sweeping system usually offers good performances but with major drawbacks. The initial cost is very high and most of time includes the purchase of a new tunable laser source or PC. The architecture is also rigid and difficult to maintain and modify in mid and long term perspective. MT9820A overcomes these difficulties by adapting to the existing installing base. Its compact format as well as its low price makes it best suitable for labs testing benches.

Continuous sweep over several tunable lasers
With its patented configuration, MT9820A is the unique solution on the market that allows you to sweep continuously over several lasers (up to 4) in order to achieve a fast full-range measurement.

MT9820A: high performance in real time
MT9820A is an unique combination of high speed electronic and optical interferometry. Up to four real time measurements are now possible with ±5pm wavelength accuracy. This allows the use of MT9820A during alignment and manufacturing process, but also for optical sensor analysis.
