Which board on OptiXtrans DC908 can support 400G/A?

Show Suggested Answer Hide Answer
Suggested Answer: C

The correct answer isMD02A. TheMD02A boardin theOptiXtrans DC908platform supports400G per wavelength, enabling high-capacity data transmission for backbone and core networks.

Key features of the MD02A board include:

High-Speed Transmission:Supports data rates up to400G per wavelength, leveraging advanced modulation techniques like DP-16QAM.

Flexibility:Compatible with various network architectures, including OTN, WDM, and Ethernet.

Scalability:Can be integrated into existing networks to boost capacity without requiring a complete overhaul.

Efficiency:Optimizes spectral efficiency, maximizing the utilization of available fiber resources.

Other options:

MD02:An earlier version of the board, typically supporting lower data rates.

MS04:Focuses on mid-range applications, not 400G.

N602:Designed for access networks rather than high-speed backbone transmission.

Wasn't there a practice question about the DC908's capabilities? I feel like it mentioned the 400G support, but I can't remember the details.

I think the board that supports 400G/A is the OTN board, but I'm not entirely sure.

This is a tricky one. I'm going to start by listing out the key details I know about the OptiXtrans DC908 and then try to deduce which board would support 400G/A.

I'm pretty confident I can figure this out. I just need to review my notes on the technical specifications of the OptiXtrans DC908 and match that to the 400G/A requirement.

Ugh, I'm not sure I even know what the OptiXtrans DC908 is. I'll have to try to reason this out based on my general knowledge of networking hardware and standards.
