Keysight’s 81490A reference transmitter is optimized to offer excellent eye quality as a reference for testing 10 GbE-LR, -ER, -SR according to IEEE 802.3ae, 100GBASE-LR4,-ER4,-SR4 according to IEEE 802.3bs and according to 10/16 G FC Fibre Channel specifications. With the integration into the Keysight LMS platform it offers seamless operation with the N4917A/B optical receiver stress test solution.

The high modulation bandwidth of up to 35GHz enables to build test setups that deliver arbitrary optical modulated signals in combination with electrical waveform generators.


  • Support for full compliance to IEEE 802.3ae -LR, -ER, -SR and IEEE 802bs -LR4, -ER4, -SR4 in combination with the N4917A/B Optical Receiver Stress Test solution.
  • 1310 nm and 1550 nm Single Mode Fiber transmitter included in one module saves time and cost.
  • Module with external laser source input for addressing 1300nm WDM bands.
  • 850nm Multimode Fiber transmitter.
  • Scalability with the integration into industry standard Keysight LMS platform extends your optical workbench capabilities.
  • Analog modulation bandwidth of 35 GHz extends the application to arbitrary optical waveform generation in combination with an electrical arbitrary waveform generator.
