On an Allied Telesis host the transceiver enumerates as a compatible unit and holds its assigned wavelength, so the Ch60 position of a mux can be lit or replaced without disturbing anything else on the fiber. The design tracks the MSA specification, and conformance is confirmed on the bench for every unit. Backed by the GreenLights4Life® Limited Lifetime Replacement Warranty.
