Standing in for the Transition Networks part of the same number, the TN-25G-DWDMCh46 matches it on the 25G rate and the Ch46 channel assignment, so the swap changes nothing in the link design. The carrier stays at 1517.94nm, the housing stays SFP28, and the cabling stays duplex LC over SMF — the surrounding mux plan never registers the substitution.

Host coding for Transition Networks equipment is loaded at the factory, and the module is identified correctly the first time it is seated, with DDM/DOM data available from that point on. Build and test follow the governing MSA, unit by unit. If a unit dies in service, the GreenLights4Life® Limited Lifetime Replacement Warranty puts a replacement in the rack. Stock is physical, not promised — it ships same or next business day.
