One-to-two optical-to-electrical converters allow a single or dual optical input to be converted into multiple electrical outputs, supporting high-speed signal measurement and distribution.

Overview

Optical-to-electrical (O/E) converters transform optical signals into electrical signals for measurement, processing, or distribution. One-to-two converters specifically allow a single optical input to be split into two electrical outputs, or handle two optical inputs with multiple outputs, enabling flexible routing and monitoring in laboratory, industrial, or broadcast applications . These modules are widely used in high-speed optical communications, photonic integrated circuit testing, and video signal conversion.

Key Features

• Channel Configuration: Available as single-channel or dual-channel modules, supporting one-to-two or more output configurations .
• Bandwidth: High-speed modules can support bandwidths up to 50–60 GHz, suitable for advanced optical communications and PAM4 signal analysis .
• Coupling Options: AC or DC coupling is available depending on the application, allowing precise measurement of varying signal types .
• Wavelength Range: Modules cover broad optical wavelength ranges, often compatible with standard telecom wavelengths (e.g., 1310 nm, 1550 nm) and visible spectrum for specialized applications .
• Control Interfaces: Many modules feature web-based interfaces or DIP switches for configuration, monitoring, and routing control, including auto change-over and manual selection modes .
• Output Types: Electrical outputs can include standard laboratory connectors (SMA, BNC) or video interfaces like 3G/HD/SD-SDI or DVB-ASI for broadcast applications .
