The AT-100G-DWDMCh37 puts 100G onto the Ch37 DWDM wavelength — 1531.90nm — from a QSFP28 port, over single-mode fiber. Allied Telesis systems identify it as a compatible optic and bring it into service without host-side changes; duplex LC cabling and DDM/DOM monitoring round out the interface.

MSA-conformant, with verification performed before any unit leaves the bench. Backed by the GreenLights4Life® Limited Lifetime Replacement Warranty.
