Compatibility: This compatible module is coded per order for your platform — add your switch model and OS release in the order notes, or email 10.4@tenfouroptics.com, and we confirm coding before it ships.

Tested & Proven: Every TenFour Optics part is coded, tested, and verified before shipment — see Tested & Proven.

Its wavelength is locked to the Ch43 grid slot, so it can be added to a loaded DWDM system without re-planning neighboring assignments — that predictability is the point of a fixed-wavelength part. The build follows the SFP28 MSA, and every module passes a conformance check first. TenFourOptics covers it with the GreenLights4Life® Limited Lifetime Replacement Warranty for the full time it is deployed. In-stock items ship same or next business day — contact 10.4@tenfouroptics.com to confirm availability and lead time.
