MT9810A
This product has been discontinued Replacement Model(s) : CMA5 , CMA50
Overview

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.


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).

Applications

Measurement Conditions Saved and Copied
Up to 10 sets of measurement conditions can be saved for each channel (one of the 10 sets can be set as the default). Moreover, when channel 1 and channel 2 use the same type of unit, the measurement conditions for one side can be copied to the other side.

Saved Measured Optical Power
A maximum of 1000 power measurements per channel can be saved, and the saved measurements can be read by remote control, permitting various analyzes and processing.

Evaluation of WDM Device Wavelength Characteristics
By combining the MG9637A/9638A Tunable Laser Source with the MT9810A, wavelength loss characteristic measurements of WDM device (filter etc. ) are possible.

Insertion Loss and Optical Attenuation Measurement of Optical Couplers/Splitters
Combining a light source and optical sensor permits measurement of the insertion loss and isolation of optical couplers and Arrayed Waveguide Granting (AWG), etc. with a wide dynamic range of 120 dB max. Moreover, the high linearity of ±0.01 dB facilitates attenuation evaluation of optical attenuators.

Optical Switching Characteristics
Optical switching times up to about 10 ms can be evaluated by inputting the analog output to an oscilloscope, etc.

Optical Fiber Loss
When an optical sensor and light source are combined, optical fiber loss can be measured. Near end and far end measurements are possible using various reference values.

Polarization Dependent Loss (PDL) of Optical Devices
The PDL of the device under test can be read directly from the variation width using the Max. and Min. functions by inputting an optical signal scrambled by a polarization controller to the DUT and measuring the output with an optical sensor.

Optical Pulse Average Power Measurement
Average power is used to evaluate the power of an optical pulse with a long repetition cycle. At this time, the optical sensor bandwidth is switched to narrow band to measure the optical pulse average power. If the pulse duty is known, the peak power can be back calculated. (However, there is some error due to the extinction ratio of the intensity modulation and the waveform distortion.)
