• PDL: ≤ 0.5 dB

The CDE is a fixed, entirely passive chromatic dispersion emulator that has been developed to test the dispersion robustness of transceivers and DSP over thousands of kilometers of transmission fiber.

Based on reliable fiber Bragg grating technology, the CDE is cost effective, it has a very low insertion loss and can emulate up to 45 000 ps/nm of dispersion in a very compact half 1U 19-inch rack module.

The C-band and L-band CDEs are offered in a multi-channel profile for testing 100G-800G optical modules at multiple wavelengths at once, or in a very wide bandwidth single-channel profile for the latest and upcoming high data rate applications.
