Agilent/Keysight J4235A

The Agilent/Keysight J4235A is a C-size, double-slot VXI transmitter module engineered for Dense Wavelength Division Multiplexing (DWDM) systems. It generates ITU-T standard wavelengths in the 1550 nm range with 50 GHz channel spacing, delivering distinct wavelengths across multiple optical ports. As a register-based VXI module, the J4235A integrates directly into existing VMEbus test architectures for optical signal generation and wavelength multiplexing applications.
