H31-341_V2.5 · Question #795
The TNG1M404DM single board is a wavelength conversion board that can multiplex 4 channels of 40 Gbit/s services to 2 channels of 200G signals.
The correct answer is A. True. Option A is correct because the TNG1M404DM is precisely a muxponder (multiplexer/transponder) wavelength conversion board designed to aggregate 4 client-side channels running at 40 Gbit/s each and map them onto 2 line-side 200G wavelengths - the higher 200G line rate…

Explanation
Option A is correct because the TNG1M404DM is precisely a muxponder (multiplexer/transponder) wavelength conversion board designed to aggregate 4 client-side channels running at 40 Gbit/s each and map them onto 2 line-side 200G wavelengths - the higher 200G line rate accommodates the client payload plus OTN framing and FEC overhead. This 4×40G-to-2×200G aggregation is the defining function of this board in optical transport network (OTN) deployments.
Option B is incorrect because it contradicts the board's documented specification; denying this capability misrepresents the board's core design purpose.
Memory tip: Break down the model number - "M" = Muxponder, "4" = 4 client ports, "04" = 40G per port. Four 40G client channels pair up into two 200G line-side signals, so each 200G wavelength carries two 40G tributaries.
