Technical Approach
Designed a dual-ring fiber backbone connecting the Plenary Hall OB Compound to International Media Centre (IMC) distribution hubs.
Configured redundant Evertz SPG synchronizers with GPS locking to guarantee jitter-free reference across 28 multi-vendor camera channels.
Established strict CCU colorimetry matching calibrated for low-glare presidential lighting and 4K HDR projection backdrops.

High-Pressure Live Faults & Engineering Solutions
CHALLENGE ENCOUNTERED:Unannounced VIP arrival caused spontaneous room reassignment 20 minutes before world leaders address.
REAL-TIME ENGINEERING FIX:Triggered emergency flyaway optical multiplexer preset, re-patching 6 CCU channels and RTS intercom panels over dark fiber trunk in 8 minutes.
Impact on Broadcast: Zero transmission delay; world feed went live flawlessly with synchronized tally and graphics.
CHALLENGE ENCOUNTERED:Severe thermal fluctuations in external outdoor fiber termination hubs reaching 42°C ambient.
REAL-TIME ENGINEERING FIX:Implemented active thermoelectric spot cooling and optical power margin monitoring on all tactical SMPTE cables.
Impact on Broadcast: Prevented optical dB attenuation drops throughout the 14-day summit.
HONEST ENGINEERING RETROSPECTIVE — “WHAT I'D IMPROVE NEXT TIME”
“In future mega-summits, I would deploy automated SMPTE ST 2110 NMOS IS-04/05 discovery for unilateral client trucks to cut initial patching times by another 40%.”
