Getting started
Product description
This section contains a description of the DPO7OE Series optical probes and
information about features, options, accessories, and recommended software.
The following optical probes in the DPO7OE Series are available.
■
DPO7OE1 33 GHz
■
DPO7OE2 59 GHz
The DPO7OE Series probes are low noise, broad wavelength optical probes that
can be used as an Optical Reference Receiver 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 probes provide an FC/PC or FC/APC optical connection for
Tektronix DPO/MSO70000 C/DX/SX model oscilloscopes for high-speed optical
signal verification.
The DPO7OE Series probes are intended to be used as test and measurement
tools for general purpose characterization of ultra-fast optical signals, and for
physical layer conformance testing of very-high bit rate, fiber-optic time-domain
optical signals such as 100 Gb/s (DPO7OE1) and 400 Gb/s (DPO7OE2)
telecommunication or data communication signals.
The DPO7OE Series can be used in conjunction with 50 GHz and higher ATI
channels on the DPO70000SX instruments, providing ample bandwidth for a
smooth BT response for up to 28 GBd data. The DPO7OE2, used in conjunction
with 70 GHz ATI channels on the DPO70000SX instrument, supports smooth BT
response for use with 53 GBd PAM4 data.
The DPO7OE Series probes have a TekConnect interface that allows them to
plug into any DPO/MSO70000 C/DX/SX model oscilloscope. Connected to
TekConnect channels, the DPO7OE Series probes provide for up to 33 GHz
bandwidth. Connected to ATI channels, the DPO7OE1 provides up to 42 GHz
electrical response; the DPO7OE2 provides up to 59 GHz electrical bandwidth
response.
