RAD-25G-DWDMCh37 RAD Compatible 25G SFP28 DWDM 1531.90nm Transceiver

One spec anchors the RAD-25G-DWDMCh37: a 1531.90nm carrier, Ch37 in the DWDM lineup, driven at 25G from an SFP28 housing. RAD platforms recognize the coding as their own, and the optic runs single-mode fiber through the usual duplex LC pairing. Swapping one in during a maintenance window amounts to seating the module and confirming its readings.
