A Practical Guide to DWDM Channel Planning on the C-band

From 100 GHz grid spacing to amplifier gain and dispersion budget, a working checklist for building a 40-channel DWDM line system.

Plan your network requirements

Evaluate the required data rate, link distance, fiber type and equipment compatibility together. Confirm connector types and the optical budget before selecting the components for your link.

Validate before deployment

Inspect and clean the fiber end faces, check the module compatibility on your target platform and verify link stability under traffic. Keep a record of the final configuration for future maintenance.
