WDMs (CWDMs and DWDMs)
CWDM and DWDM Modules

Request for Quotation (RFQ)


WDMs (CWDMs and DWDMs) combine or separate signals with different wavelengths on an optical fiber.

This allows for bidirectional communication and a multiplication of capacity on a single fiber.

ARIA WDMs are manufactured using a proprietary optical bench platform which significantly improves optical performance and reduces manufacturing cost.

These modules are highly customizable and are available and 3 primary size formats: module, LGX cassette, and 2U LGX cassette.
