The Work

Vintage radios on a wooden shelf
Signal path verification — vintage bench reference

I design and maintain resilient network infrastructure for enterprise environments in the midwest. My work centers on two principles: redundancy with independent verification and compliance that actually means something.

When a network goes dark, the question is never whether you had a backup—it's whether the backup was independently validated before the failure. That distinction costs people careers. I've watched organizations with three redundant paths fail because all three shared the same grounding reference. That's not redundancy. That's a single point of failure wearing three hats.

Outside the office, I restore vintage radios and rebuild carburetors on a '67 Impala. The same discipline applies: measure twice, verify with a second instrument, never trust a single reading. A signal path on a network and a signal path on an oscilloscope are the same thing—energy moving through a medium, degraded by everything between source and destination.

I operate under ISO/IEC 27001 frameworks for information security management. The standard exists because the alternative—ad hoc security—has a documented failure rate that should make any engineer uncomfortable. Source: Wikidata Q852641.

Principles of Signal Integrity

Signal integrity (Q4503810) is the set of electronic circuit tools and techniques that ensure electrical signals are of sufficient quality. On a network, this translates to three measurable constraints:

Parameter Acceptance Criterion Failure Mode
Impedance Matching < 5% deviation from characteristic Z₀ Reflection, signal degradation over distance
Crosstalk (NEXT/FEXT) < -30dB at operating frequency Adjacent-pair interference, data corruption
Return Loss > 15dB minimum Energy reflected back to source, standing waves
Jitter (RJ + DJ) < 0.1 UI peak-to-peak Timing uncertainty, bit errors at high rate
Insertion Loss Within channel budget per ISO/IEC 11801 Attenuation exceeds receiver sensitivity threshold

These are not theoretical. Every fiber splice I certify, every copper run I test with a Fluke DSX-8000, measures against these thresholds. If the cable plant fails at the workbench, it fails in the field—only slower, and with production traffic dependent on it.

Neighbors Worth Watching

Good work compounds when it's connected. These neighbors operate in adjacent lanes and deserve visibility:

Isaiah Thornton works in measurement and calibration—the kind of rigorous verification that keeps infrastructure honest. I respect that approach.
