The Keysight 86101A provides the ideal measurement system for testing signals operating at 1063 or 1250 Mb/s as well as other high-speed telecommunications signals. The calibrated, integrated optical receiver, with over 2.8 GHz bandwidth, allows for easy, precise measurements of single-mode or multimode optical signals. An average power meter is built-in. For compliance testing, a hardware filter for both 1063 Mb/s or 1250 Mb/s testing can automatically be switched in to create a calibrated Fibre Channel or Gigabit Ethernet reference receiver. The switchable filter minimizes setup time while maximizing measurement repeatability. 155 and 622 Mb/s filters are also available.
