Flexibility for Every Application The MT9810A offers superior accuracy and reliability for evaluating a wide range of optical devices and systems. It has a full range of plug in type high output DFB-LDs complying with the ITU-T recommended wavelength grid, as well as high accuracy optical sensors. It ensure effective support for future needs as a basic measuring instrument.
Superior operability is achieved through use of an easy to read 7 mm high, seven segment and full dot matrix display. And a complete range of replaceable optical connectors eliminate all connection problems while making cleaning easy too. GPIB and RS-232C interfaces are standard and configuration of a remote control system is simplified using the bundled LabVIEW software drivers.
Wide Dynamic Range
Optical loss of up to 120 dB can be measured using the high output (+10 dBm) light sources and the high sensitivity (-110 dBm min.) sensors.
High Output, High Stability DFB-LD Light Sources
The DFB-LD light sources have a high output of +10 dBm while achieving a stability of better than < ±0.005 dB and a center optical frequency stability of better than < ± 2 GHz, facilitating high-stability and high reliability measurement.
Conforms to ITU-T Wavelength Grid
A complete line up of DFB-LD light sources for optical frequencies meeting the ITU-T recommendations for Dense WDM (DWDM) networks (191.7 to 195.9 THz at 100 GHz interval) is available.
High Accuracy Optical Power Measurement
Under reference conditions, the optical power measurement uncertainty is < ±2%, and under actual operating conditions, it is < ±3.5% with a linearity of better than < ±0.01 dB. These excellent specifications permit measurement of optical power with high accuracy and repeatability.
Sensors with High Return Loss and Low Polarization Dependency
Even without a reflection / suppression adapter, the sensor return loss and polarization dependency are 40 dB min., and 0.02 dB max. respectively, making them ideal for evaluating devices and systems that use optical amplifier.
High Speed Analog Output
The optical sensors have a maximum bandwidth of 100 kHz (approx. 3 dB), permitting measurement of optical power variations with a response speed of approx. 10 ms.

GPIB and RS-232C I/F
Since GPIB and RS-232C interfaces are standard, measurement can be controlled from a remote PC. In addition, the LabVIEW R software driver bundle makes it easy to configure a remote measurement system.
Variable Optical Power Measurement Interval and Bandwidth
The center optical frequency of the DFB-LDs can be varied in a range of < 60 GHz (approx. < 0.5 nm). Moreover, it can be displayed in frequency and wavelength units [lambda (m) = c (m/s)/f (Hz), where c is the velocity of light in a vacuum (2.99792 x 108 m/s)].
Variable Optical Frequency
The best optical power measurement interval can be set according to the application; for example, a long interval for long term measurement, and a short interval for high speed measurement.
Additionally, the average power of a pulsed optical signal can be measured by narrowing the band, and the variations in optical power at optical switching can be measured by widening the band.
Measurement of Max. and Min. Optical Power and Variation
There is no need to save the measured optical power in memory because the maximum and minimum optical powers and variation are always displayed, permitting real time evaluation of optical stability and polarization dependent loss (PDL).
