MP2110A FUNCTIONS

Slashes Measurement Times

Reduces Measurement Times

With the All-in-one built-in BERT and sampling oscilloscope, measurement results can be captured at once while displaying the Eye pattern simultaneously. Consequently, all measurement results required for evaluating multi-channel optical modules/devices can be seen at a glance to greatly reduce measurement times.

High-Speed Sampling for Fast Eye Margin Tests

The BERTWave MP2110A performs high-speed sampling of up to 250 ksamples/s for 2ch simultaneously. Additionally, the built-in automatic Mask Margin test function requires about 5 seconds to complete capture of 1 million samples of a 25 Gbit/s signal, slashing Eye pattern analysis times by about 65% in comparison to previous instrument generations.

More Accurate Performance

Sampling Oscilloscope Performance

The BERTWave MP2110A sampling oscilloscope has all the performance needed for measuring 100 GbE and OTU4, etc., modules as well as optical devices used in optical modules.

  • Bandwidth
    Optical: 35 GHz (SMF), 25 GHz (MMF)
    Electrical: 40 GHz
  • Sensitivity: –15 dBm (typ., SMF)
  • O/E Noise: 3.4 µW (typ., SMF)
  • Intrinsic Jitter: 200 fs rms (typ.,using high-accuracy trigger option)
The wideband O/E ensures that the characteristics of directly modulated optical signals and optical modules for long-distance communications are drawn more accurately than by previous instrument generations.

Moreover, the high sensitivity of –15 dBm (typ. ,SMF) assures DUT Eye pattern and Mask Margin measurements even for measurement systems with possible signal attenuation by optical switches, etc. Further, the noise of the sampling oscilloscope sampler is 3.4 µW (typ.,SMF), and a high-accuracy trigger option of 200 fs rms (typ.) can also be installed. This high performance assures accurate measurement to improve production-line yields.

Wideband Operation Frequency

In the standard configuration, the BERTWave MP2110A BERT operates at bit rates of 24.3 Gbit/s to 28.2 Gbit/s. This range can be extended optionally to support bit rates of 9.5 Gbit/s to 14.2 Gbit/s, enabling use for various applications including 10 GbE and 100 GbE.

Excellent PPG/ED Performance

The BERTWave MP2110A PPG has a low data Jitter of just 600 fs rms (typ.) for accurate measurement of the characteristics of optical modules, optical devices, etc. Additionally, the 25 mV (typ.) ED supports BER measurement of low-amplitude signals resulting from transmission path losses, helping improve DUT yields.

Versatile Measurement Functions

Amplitude/Time Tests

Measurement of many parameters is supported, including 0 level, 1 level, SNR, Eye close ratio, Eye amplitude, Eye height, Eye width, Jitter p-p, Jitter rms, Extinction Ratio, rising edge time, falling edge time, Duty cycle distortion, average power, and OMA.

Eye Mask/Mask Margin Tests

Automated Mask Margin tests simplify testing. In addition, yields are improved by shortening the time required for Mask Margin tests measuring compliance with standards.

  • Automatic measurement in less than 1 second
  • Real-time Margin measurement
  • Mask bit count and rate selection

Histogram

Measuring the mean, standard deviation and dispersion of the data distribution within a set range supports component analysis of waveform data as an aid to troubleshooting.

Reference Trace Function

Saving waveform data using this functions enables comparison with current waveform data for analyzing changes over time.

Easy Operation

With synchronization of each channel, simply setting one channel of the BERTWave MP2110A sets all channels simultaneously and since the test pattern can be changed for each channel, crosstalk interference tests required by multi-channel transmission equipment, such as Active Optical Cables (AOC) and Direct Attach Cables (DAC) systems, are easy. In addition, optical Eye pattern analysis is supported for up to 2ch.
Furthermore, the MP2110A has retained the simple settings and easy-to-use interface of all models in the BERTWave series; backwards compatibility with MP2100B remote commands assures trouble-free instrument upgrades. Additionally, the stable operation resulting from the built-in PC guarantees performance irrespective of the operation environment.

Configure Effective Measurement Systems

Previous measurement systems were extremely complex due to the need for a separate BERT as the signal source and a sampling oscilloscope for Eye pattern analysis. Incorporating a BERT and sampling oscilloscope into the All-in-one BERTWave MP2110A greatly simplifies measurement system configuration.
Since a 4ch BERT and 2ch sampling oscilloscope are installed in one cabinet, measurement systems are easier to configure and control, enabling simultaneous Tx/Rx measurements of optical modules and optical devices, such as multi-channel QSFP28. Increasing the number of channels slashes the measurement time for multi-channel optical modules and devices that would otherwise require longer measurement times.
