During my industrial attachment at SEACOM CLS in Mombasa, I gained practical experience in submarine cable operations, data center connectivity, and ISP core network systems. I worked with engineers on both routine operations and field activities, strengthening my technical and teamwork skills.

• Performed daily, weekly, and monthly maintenance checks in the AVR, MSB, Collocation, and Backhaul rooms — recording environmental readings, UPS parameters, generator runtime, and monitoring HVAC systems.
• Assisted in preventive and corrective maintenance to ensure continuous operation of submarine and terrestrial network systems.
• Worked with DWDM systems, ODFs, routers, switches, inverters, and rectifiers, gaining hands-on telecom and power management experience.
• Carried out fiber patching, running and labeling patch cords between ODFs, routers, and switches, ensuring proper connectivity and documentation.
• Supported new equipment installations and upgrades, including Akamai CDN setup, assisting in racking, cabling, and post-installation testing.
• Used OTDR, OLS, OPM, and a 100G tester for fiber link testing and troubleshooting, checking optical power levels, losses, and link performance.
• Participated in field work at Icolo MBA1 and MBA2 data centers, assisting in fiber tracing, equipment verification, and documentation of SEACOM’s interconnections.
• Helped engineers with site research, technical reporting, and equipment evaluations during maintenance planning.
• Guided visiting engineering students during educational tours, explaining SEACOM’s submarine cable and backbone operations.
• Worked with the Network Operations Center (NOC) to observe fault monitoring, incident response, and escalation procedures.
• Volunteered for night shift operations when extra manpower was needed, showing reliability and teamwork.
• Completed a Core ISP Network Simulation Project in GNS3, configuring MPLS, IS-IS, and iBGP, assigning IP schemes, and simulating inter-ISP routing.

Key Skills Gained: DWDM operations, fiber diagnostics, network troubleshooting, routing protocols, ISP design, and telecom system maintenance.
