1546.12nm is the number that matters on this page: the EKI-25G-DWDMCh28 holds that carrier — Ch28 in the DWDM sequence — while moving 25G through an SFP28 cage on Ekinops systems. Connection is duplex LC onto single-mode fiber, and DDM/DOM readouts are available from first link-up. For the spares shelf, keeping one code per channel is all the bookkeeping this approach requires.

Because each transceiver is verified on its wavelength against MSA-defined parameters, substituting it into a live channel plan is uneventful — the mux port sees exactly the carrier it expects.
