o2e

Optical-to-Electrical Converter

Coherent Solutions o2e is a DC-coupled amplified Optical to Electrical converter that brings optical signal measurement capability to real-time oscilloscopes. With 25 GHz of analogue electrical bandwidth, it is an ideal optical front-end for testing high-speed multilevel intensity modulated optical signals. With the 4-channel o2e, you can characterize multi-lane signals from various IEEE ethernet compatible transceivers.

Key Features

  • DC Coupled
  • Amplified RF output
  • 25GHz of bandwidth
  • 50/125 μm multi-mode fiber input

Ideal O-to-E for IEEE Ethernet Transceivers

Many of IEEE ethernet standards use multiple channels to achieve high data transmission rates such as 100Gbps, 200Gbps and 400Gbps. The 4-Channel o2e lets you perform simultaneous multi-channel signal characterization in a single package, drastically reducing the complexity of the test setup and saving you valuable time.

Powerful Optical Signal Characterization with Real-time Oscilloscopes

Real-time oscilloscope lets you measure and characterize non-repeating live data streams without the need for a trigger signal. o2e adds optical signal measurement capability to the powerful and versatile real-time oscilloscopes. Just connect the optical fiber to o2e and characterize your signal.

Characterization of optical PAM4 signals

Measuring multi-level intensity modulated optical signals requires DC-coupled optical to electrical converters. o2e‘s 25GHz of analogue bandwidth and its amplified output makes it the perfect solution to PAM4 optical signal analysis.
