Tektronix High Bandwidth Optical Probe Series Product Description

The DPO7OE Series Optical probes can be used as Optical Reference Receivers (ORR) for high speed serial data signals (using selectable Bessel-Thomson ORR filters), or can be used as a conventional O/E converter for general wide-bandwidth optical signal acquisition. The DPO7OE Series is compatible with DPO/MSO70000 C/DX/SX models. Connect to TekConnect channels for up to 33 GHz electrical bandwidth. Connected to ATI channels, the DPO7OE1 provides up to 42 GHz electrical response; the DPO7OE2 provides up to 59 GHz electrical bandwidth response.

Features and benefits

  • Accurate Optical Reference Receiver (ORR) filters for 25 GBd, 26 GBd, 28 GBd, and 53 GBd optical networking standards ensure highest measurement accuracy and correlation
  • Versatile design delivers Bessel-Thompson ORR specified bandwidths or unfiltered response up to 59 GHz on multiple channels
  • Broad wavelength with FC/PC or FC/APC connector options
  • High sensitivity and low noise provide best SNR for high-speed signal analysis
  • Enables deep analysis of PAM4 and PAM2 (NRZ) signaling, equalization and error detection/isolation
  • Compatible with ATI and TekConnect® channels for maximum performance or channel density


  • Datacenter networking equipment design validation
  • Research - Characterization of laser-based velocity measurement system (e.g. PDV, BLR) and other optical phenomena
  • System debug of optical interfaces using a real time oscilloscope's unique debug features
