Senior Fiber Optic Splicer

About the role

We are seeking experienced Senior Fiber Optic Splicers to support fiber break/fix, remediation, testing and restoration activities within an active hyperscale data center environment. This is a production-level position for technicians who can independently diagnose and resolve fiber defects in both live/in-service and non-live fiber environments. The technician will be expected to own assigned defects from initial ticket review through repair, testing, documentation and closure. Candidates must have recent, hands-on experience with single-fiber fusion splicing, ribbon/mass fusion splicing, SC connectivity, MTP/MPO systems and MMC high-density fiber connectivity. This is not a learn-on-the-job position, and routine technical issues should be resolved without requiring escalation back to the client.

Responsibilities

• Perform single-mode, single-fiber fusion splicing using repeatable fiber preparation, cleaving and splicing procedures.
• Perform 12-fiber ribbon and mass fusion splicing, including ribboning fibers from loose-tube cable.
• Work with SC, MTP/MPO and MMC fiber connectivity in high-density data center environments.
• Install and repair splice-on connectors, pigtails, fan-outs and related fiber assemblies.
• Diagnose and repair defects identified through audits, inspections, testing or trouble tickets.
• Interpret fiber drawings, cable schedules, port assignments, splice plans and methods of procedure.
• Understand MTP/MPO polarity methods, including Methods A, B and C.
• Verify MTP/MPO key orientation, pinned versus non-pinned configurations, gender and trunk/harness/cassette architecture.
• Perform OTDR testing and interpret traces to identify events, excessive loss, reflections, breaks and fault locations.
• Conduct insertion-loss testing using optical light sources and power meters.
• Verify results against applicable loss budgets and project acceptance requirements.
• Inspect and clean SC, MPO and other fiber end faces using appropriate inspection probes and cleaning tools.
• Apply end face pass/fail standards consistent with project requirements and IEC 61300-3-35.
• Follow live-environment safety procedures and never inspect an energized fiber directly.
• Work strictly according to the approved ticket and method of procedure.
• Avoid disconnecting, moving or disturbing fiber components that are not included in the assigned scope.
• Document repairs, test results, photographs and supporting evidence before closing tickets.
• Provide required morning, progress and end-of-day status updates.
• Maintain splicing machines, cleavers, testing equipment and inspection tools in proper working condition.
• Follow site safety requirements, including ladder, fall-protection, access-control and tool-control procedures.

Required Qualifications

• Demonstrated professional experience performing fiber fusion splicing in data center, colocation, enterprise or mission-critical environments.
• Recent hands-on experience working with live/in-service fiber infrastructure.
• Production-level proficiency in:
  • Single-fiber fusion splicing
  • Ribbon or mass fusion splicing
  • Ribboning loose-tube fiber
  • SC terminations and patching
  • MTP/MPO connectivity
  • MMC high-density connectivity
• Ability to independently diagnose, repair, test and close fiber defects.
• Hands-on experience operating core-alignment fusion splicers such as:
  • Fujikura 70S/90S series
  • Sumitomo Type-72/Q-series
  • Comparable professional fusion-splicing equipment
• Proficiency with OTDRs, optical power meters, light sources and fiber inspection microscopes.
• Ability to interpret OTDR traces rather than only operate the test equipment.
• Understanding of insertion loss, loss budgets, splice-loss thresholds, reflectance and fiber cleanliness.
• Ability to read fiber drawings, port maps, cable schedules and technical procedures.
• Strong documentation and ticket-closure discipline.
• Ability to work independently without routine client escalation.
• Comfortable working in a safety-controlled, construction-oriented data center environment
