CWDM Converter

About This Tool

CWDM Converter computes channel mapping by aligning an input wavelength to the nearest CWDM grid channel. It accepts input_wavelength_nm, grid_spacing_nm, and optional base and tolerance values. The tool outputs mapped_channel_nm and channel_index, along with a validity flag and notes to guide interpretation. This enables planning, verification, and documentation of CWDM channel plans without hardware.

Conceptually, the mapping relies on a fixed wavelength grid defined by ITU-T CWDM standards. The algorithm rounds the input to the nearest grid point, computes the channel index from the offset relative to the base wavelength, and checks tolerance to determine validity. This deterministic approach helps engineers reproduce channel assignments across projects.

Who benefits: telecom network designers, system integrators, field engineers, operators needing quick channel mapping, validation against a plan, or audit-ready documentation. It reduces manual calculation errors and speeds grid-based planning.

Core features include mandatory grid spacing and base wavelength inputs; optional tolerance and batch mode; outputs include mapped_channel_nm and channel_index; provides a validity flag and notes for out-of-range or non-conforming inputs. It supports common grids such as 20 nm or 8 nm and can document channel labels like Ch-08 for reporting.
