Tektronix OM2210 Coherent Receiver Calibration Source

The OM2210 Coherent Receiver Calibration Source includes the capability and software needed for coherent optical receiver calibration. Equipped with two independent free-running lasers and a precision polarization switch, the OM2210 is able to excite the coherent receiver with a known-polarization signal so that the receiver’s linear transfer function can be extracted.

OM2210 parameter measurements

To measure coherent optical modulation using a minimum of assumptions about the transmitter, it is necessary to measure and correct for any imperfections in the coherent receiver. The OM2210 uses two independent free-running lasers and a precision polarization switch to excite the coherent receiver with a known-polarization signal so that the receiver’s linear transfer function (optical electric field to voltage matrix) can be extracted. The lasers can be tuned across an entire band to obtain measurements vs. channel frequency and heterodyne frequency. The results are plotted and saved in a .mat format file.




OM2210 Coherent Receiver Calibration Source includes the materials and software needed for receiver calibration.

Measurement Typical Uncertainty Note:

  • Channel Skew 0.5 ps between any 4 channels
  • Crosstalk -40 dB Min measurable between any pair of the 4 channels
  • Quadrature phase error 0.2 degrees between quadrature channels
  • Optical phase 0.4 degrees between polarization channels
  • Path gains 0.1 dB relative gains between channels

The lasers used in the OM2210 and OM2012 products integrate a cooled External-cavity Diode Laser (ECDL). The ECDL uses a thermally tuned etalon filter to achieve single-mode operation at selectable wavelengths. The tunable laser has no moving parts and shares many design elements of standard Distributed Feedback Lasers (DFB).

The tunable laser has low Relative Intensity Noise (RIN), a high Side-mode Suppression Ratio (SMSR), a narrow linewidth, and accurate wavelengths over typical operating conditions. The product complies with the stringent requirements of 300-pin Multisource Agreement (MSA) transponders and discrete line cards.

Additional requirements

All hardware needed for coherent receiver calibration is provided with the OM2210 with the following exceptions:

  • Either the OM4000 Series OMA or OM1106 Software is required.
  • The computer is not included. See the OM4000 Series datasheet for computer requirements.
  • The oscilloscope is not provided. The software is compatible with many oscilloscopes. Check for compatibility at time of order. The minimum requirements include: >10 GS/s per channel, >2.5 GHz bandwidth per channel, 4 channels, LAN connection.
  • The DUT is not provided. The DUT must be a dual-polarization intradyne receiver. If the outputs are differential, only 4 may be measured at one time, although TriMode probes are supported that provide automatic switching between P and N.


This device is a Class 1M laser product for use only under the recommended operating conditions and ratings specified in the data sheet. Use of controls or adjustments or performance of procedures other than those specified in the data sheet may result in hazardous radiation exposure.

Invisible laser radiation – Do not view the laser output from this device directly with optical instruments.

This device complies with 21CFR1040.10 except for deviations pursuant to Laser Notice No. 50, dated June 24, 2007.
