OE6250G-M - O-E converter, 25 GHz Bessel-Thomson response, 36 GHz flat response
OE695G - Optical to Electrical Converter
These wide- band multi-mode optical-to-electrical converters are designed for measuring optical communications signals. They connect to Teledyne LeCroy real-time oscilloscopes and provide capability for physical layer signal assessment using a variety of oscilloscope tools, such as SDAIII-CompleteLinQ Serial Data Eye, Jitter, Noise and Crosstalk Analysis, mask testing, serial triggering and decoding, and other compliance and debug tools. Maximum data rate test capability is >11.317 Gb/s with reference receiver, or 12.5 Gb/s without.

The OE6250G-M optical-to-electrical converter enables measurement of intensity-modulated optical signals up to 28 Gbaud and beyond on LabMaster or WaveMaster series real-time oscilloscopes. As a fully calibrated module, the OE6250G-M integrates seamlessly into the oscilloscope software to give optical intensity measurement straight out of the box. Teledyne LeCroy’s extensive toolset includes powerful analysis tools for NRZ, PAM4, and other signal types, and enables custom signal processing and reference receiver implementation.

High-bandwidth Optical Performance

With up to 36 GHz of optical bandwidth, the OE6250G-M has the high performance necessary to acquire NRZ and PAM4 signals at 28 Gbaud and higher. As a fully calibrated optical-to-electrical converter, the OE6250G-M’s response characteristics are combined with those of the oscilloscope, and compensated to an ideal response throughout the measurement system.

A Complete Measurement Toolset

The OE6250G-M enables high-speed optical signals to be analyzed using Teledyne LeCroy’s industry-leading software and solutions toolset. Apply software clock-recovery using standard or custom PLL types, and analyze up to four NRZ signals simultaneously with eye diagrams, jitter and noise analysis, and extensive visualization options. Or leverage the PAM4 Signal Analysis package, with the most sophisticated eye, jitter and noise analysis available.
