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

The 1557.36nm carrier — Ch21 — is the reason this part exists: the RAD-1G-DWDMCh21 pins a 1G signal to that wavelength so it can share single-mode fiber with the rest of a DWDM channel set. Form factor is SFP and the connector is duplex LC. Documentation and inventory match the printed code, so field techs can verify the part at a glance.

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.

Monitoring runs over DDM/DOM for the duration. Before release, each module passes wavelength confirmation and MSA conformance screening at the bench, so the Ch21 slot gets exactly what the plan assigned it.
