While upgrading a campus network, I was tasked with installing a new fiber optic run between two buildings.

Ensure a reliable splice and termination that meets performance specs and documentation standards.

I surveyed the route, pulled the cable using a fiber puller, performed a mechanical splice with a fusion splicer, inspected loss with an OTDR, terminated both ends with LC connectors, labeled each fiber, and recorded splice loss and test results in the project log.

The link achieved 0.2 dB loss, passed certification, and was documented for future maintenance, resulting in zero outages during the rollout.

During a client briefing on upgrading their voice system, the client asked about analog vs. digital lines.

Explain differences and implications for signal quality in simple terms.

I described that analog transmits continuous waveforms susceptible to noise and attenuation, while digital encodes data into discrete bits, allowing error detection, regeneration, and higher bandwidth. I highlighted that digital signals maintain quality over longer distances and support compression.

The client understood the benefits and approved the migration to VoIP, improving call clarity and reducing maintenance costs.

I was assigned to test a live 10 kV distribution line during a scheduled outage window.

Perform the test safely while ensuring no exposure to hazardous voltage.

I locked out and tagged the section, verified zero voltage with a calibrated meter, wore insulated gloves and flame‑resistant clothing, used insulated tools, and maintained a safe distance with a spotter. I also completed a pre‑task safety briefing and documented the lockout in the safety log.

The test was completed without incident, confirming line integrity and allowing the outage to end on schedule.

Our company was upgrading a cellular backhaul network in a metropolitan area.

Ensure the upgrade met all FCC emission and licensing requirements.

I reviewed the relevant Part 22 and Part 90 rules, verified that all equipment had FCC IDs, submitted any required filing forms, performed spectrum scans to confirm no spurious emissions, and logged the compliance checks in the project management system.

The upgrade passed the FCC audit with zero violations, avoiding fines and enabling the network to go live on schedule.

A small business client called after their internet connection dropped during peak sales hours.

Restore service quickly while calming the customer and preserving the relationship.

I listened actively, apologized, and assured them I’d prioritize the issue. I ran remote diagnostics, identified a faulty ONT, coordinated a same‑day field visit, and kept the client updated every 15 minutes. I also offered a temporary hotspot as a workaround.

Service was restored within 2 hours, the client expressed appreciation for the communication, and they renewed their contract for another year.

A residential customer called about intermittent Wi‑Fi drops.

Explain the cause and solution in layman's terms.

I compared the Wi‑Fi signal to a water pipe, saying congestion is like a blockage. I described that too many devices were competing for bandwidth and suggested moving the router to a central location and using a dual‑band network. I avoided jargon and used analogies they could visualize.

The customer understood the steps, repositioned the router, and reported stable connectivity the next day.

A rural tower site reported occasional loss of backhaul connectivity during windy conditions.

Identify and resolve the root cause of the intermittent link.

I started with a baseline performance log, then checked physical layer components: inspected antenna alignment, verified cable integrity, and monitored power supply stability. I used a spectrum analyzer to detect RF interference, and correlated outages with wind speed data. I discovered a loose coax connector that vibrated in high winds, reseated it, and added a strain‑relief clamp.

Connectivity stabilized, downtime dropped from 30 % to less than 2 %, and the client reported improved service reliability.

During a campus network rollout, a new edge router powered on but showed no IP address on its WAN interface.

Diagnose and resolve the DHCP acquisition failure.

I verified physical connections, confirmed the correct VLAN tagging, checked the DHCP server scope, and used a packet capture on the router to see DHCPDISCOVER packets. I discovered that the upstream switch port was set to a static IP mode, blocking DHCP. I reconfigured the switch port to trunk mode with the appropriate VLAN and enabled DHCP relay.

The router obtained an IP within seconds, and the network segment became operational without further issues.
