Which of the following ways does Huawei's financial data center transmission solution use to reduce transmission delay? (Multiple Choice)

Question

Options

• ANo DCM
• BVarious FEC packages are adjustable
• COptimizing fiber paths
• DOptimize chip processing time

• A
  100% (40)

Explanation

All four options represent genuine techniques Huawei employs to minimize transmission delay in financial data center networks, where microseconds matter for trading and settlement systems.

A (No DCM) is correct because Dispersion Compensation Modules add physical latency to the optical path; eliminating them removes that delay penalty. B (Adjustable FEC) is correct because Forward Error Correction adds processing overhead - making FEC type and strength tunable lets operators use lighter correction when link quality allows, shrinking processing delay. C (Optimizing fiber paths) is correct because light travels at a finite speed through fiber, so a shorter, more direct physical route directly reduces propagation delay. D (Optimizing chip processing time) is correct because the ASICs and FPGAs that process optical signals introduce processing latency; faster chip pipelines lower the end-to-end delay.

There are no distractors here - this is an "all of the above" scenario where every technique targets a distinct layer of the delay stack (physical medium, signal processing, forward error correction, and hardware pipeline).

Memory tip: Think of delay as having four sources - the glass (fiber path), the hardware (chip processing), the correction overhead (FEC), and the extra gear (DCM). Huawei's solution attacks all four simultaneously: shorten the glass, speed the chip, tune the correction, and remove the gear.
