OE695G Overview

The OE695G is designed to help troubleshoot optical-to-electrical signal integrity issues at the
board level. For system integrators who measure both electrical and optical signals in their
products, the OE695G provides electrical measurements on optical signals, while taking full
advantage of the LeCroy real-time oscilloscope’ tool set and the broad debugging capabilities of
the LeCroy Serial Data and Crosstalk Analysis software options.

When connected to the oscilloscope, the OE695G becomes an integrated part of the
oscilloscope. Power is supplied to the OE695G by the oscilloscope (no external power supply is
needed), and the OE695G communicates to the oscilloscope its identity and scaling information.
The Optical Wavelength, Dark Calibration and Reference Receiver functions are all controlled
from the oscilloscope’s user interface.

The OE695G is unique in that it operates with a real-time oscilloscope, not a sampling
oscilloscope, and uses a digital signal processing (DSP) filter to enable a user-selectable
reference receiver response. Since the optical input signal is input to a real-time oscilloscope, it
is possible to use the contiguous data acquisition of the real-time oscilloscope to obtain serial
data pattern knowledge and provide Tj, Rj, and Dj decomposition to very high accuracy, like
what is done with high-speed electrical serial data signals. The low cost and general purpose
utility of this optical to electrical converter makes it ideal for those who are already using real­time oscilloscopes for electrical serial data measurements, and need to also measure optical
serial data signals as well.

Key Features:

 Frequency range DC to 9.5 GHz (electrical, -3 dB)
 Selectable reference receiver support from 8 Gb/s FibreChannel (8G FC) to 10 Gb/s

FibreChannel with Forward Error Correction (10G FC FEC), Custom (<11.5 Gb/s).
Selectable settings include:

*Cannot meet reference receiver specification past 9.5 GHz.
