ADVA-1G-DWDMCh21 ADVA Compatible 1G SFP DWDM 1557.36nm Transceiver

Ch21 — 1557.36nm on the DWDM grid — is where the ADVA-1G-DWDMCh21 sits, moving a 1G payload through an SFP slot on ADVA equipment. The host reads it as the expected part at insertion; nothing stands between racking it and passing traffic. Fiber-side it is an SMF optic with duplex LC termination and full DDM/DOM reporting.

• Form Factor: SFP

• ITU Channel: Ch21
• Wavelength: 1557.36nm

Because the emitter is fixed to the Ch21 assignment, the module joins a populated channel plan without shifting anything already lit — the remaining wavelengths keep their lanes. Conformance to the SFP MSA is verified per unit ahead of shipment. Backed by the GreenLights4Life® Limited Lifetime Replacement Warranty. Stocked for immediate turnaround, it ships same or next business day.
