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. The results are plotted and saved inMAT format. Configuration information is stored in an SQL database.

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.

The following operating specifications were used in the design of the tunable laser:

  • ITU-T G.692 
  • Telcordia GR-253 
  • Telcordia GR-63 CORE NEBS
  • Telcordia GR-468 CORE

Operating conditions

This is the stThe OM2012 Tunable Laser is designed for metro and long-haul DWDM applications at 50 GHz grid spacing and below. The performance of the laser allows high-performance, extended transmission distances depending on the modulation, optical amplifier noise figure and amplifier spacing, dispersion map, and other link design factors.art of your concept.

Additional requirements

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

  1. Either the OM4000 Series OMA or OM1106 Software is required.
  2. The computer is not included. See the OM4000 Series data sheet for computer requirements.
  3. 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.
  4. 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.
