How many 50 GHz channels does the 16-WXC-FS support on each port?

The correct answer is A. 96. Option A (96) is correct because the 16-WXC-FS (Flex Spectrum Wavelength Cross-Connect) supports the full ITU-T C-band grid of 96 channels at 50 GHz spacing per port, spanning the standard C-band range (~191.35–196.10 THz). Option D (40) is a common trap - 40 channels…

Explanation

Option A (96) is correct because the 16-WXC-FS (Flex Spectrum Wavelength Cross-Connect) supports the full ITU-T C-band grid of 96 channels at 50 GHz spacing per port, spanning the standard C-band range (~191.35–196.10 THz). Option D (40) is a common trap - 40 channels corresponds to 100 GHz spacing, which is half the density of 50 GHz. Options B (88) and C (80) don't correspond to any standard ITU-T channel plan and are plausible-sounding distractors designed to catch candidates who confuse partial or proprietary configurations with the full grid.

Memory tip: Think "50 GHz = 96 channels" - the tighter the spacing, the more channels you pack in. Since 50 GHz is twice as dense as 100 GHz (which gives 48 channels in some implementations), you get roughly double the channels. The number 96 is the industry-standard C-band ceiling for 50 GHz DWDM grids.
