Fiber installation

  • Single-Mode Fiber InstallationInstalling OS2 single-mode fiber for longer-distance connections, high-capacity network backbones, and connectivity between buildings.
  • Multimode Fiber InstallationInstalling OM3 and OM4 multimode fiber for compatible high-speed connections inside buildings, network rooms, and equipment facilities.
  • Fiber Backbone CablingConnecting main distribution frames (MDFs), intermediate distribution frames (IDFs), server rooms, and network equipment across floors or departments.
  • Building-to-Building FiberEstablishing reliable connections between separate buildings, warehouses, offices, and facilities using appropriately rated fiber and protected pathways.

Fiber termination, testing & maintenance

  • Fiber Optic Fusion SplicingPermanently joining optical fibers using precision fusion-splicing equipment to create low-loss connections for new installations, extensions, and repairs.
  • Fiber Termination & Patch PanelsInstalling fiber enclosures, patch panels, adapters, connectors, and splice trays for organized and serviceable fiber connectivity.
  • Fiber Testing & CertificationEvaluating fiber connections using optical loss testing and, where appropriate, OTDR testing to identify faults and verify installed-link performance.
  • Fiber Repair & TroubleshootingLocating damaged cables, investigating excessive signal loss, replacing faulty connections, and restoring fiber links affected by damage or installation problems.
